- ##### Initialization and de-initialization functions #####
- ===============================================================================
- [..] This section provides functions allowing to:
- (+) Initializes the Flash interface, the NVIC allocation and initial clock
- configuration. It initializes the systick also when timeout is needed
- and the backup domain when enabled.
- (+) de-Initializes common part of the HAL.
- (+) Configure The time base source to have 1ms time base with a dedicated
- Tick interrupt priority.
- (++) SysTick timer is used by default as source of time base, but user
- can eventually implement his proper time base source (a general purpose
- timer for example or other time source), keeping in mind that Time base
- duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
- handled in milliseconds basis.
- (++) Time base configuration function (HAL_InitTick ()) is called automatically
- at the beginning of the program after reset by HAL_Init() or at any time
- when clock is configured, by HAL_RCC_ClockConfig().
- (++) Source of time base is configured to generate interrupts at regular
- time intervals. Care must be taken if HAL_Delay() is called from a
- peripheral ISR process, the Tick interrupt line must have higher priority
- (numerically lower) than the peripheral interrupt. Otherwise the caller
- ISR process will be blocked.
- (++) functions affecting time base configurations are declared as __weak
- to make override possible in case of other implementations in user file.

- ##### How to use this driver #####
- ==============================================================================
- [..]
-
- *** Configuration of top level parameters related to ADC ***
- ============================================================
- [..]
-
- (#) Enable the ADC interface
- (++) As prerequisite, ADC clock must be configured at RCC top level.
- Caution: On STM32F1, ADC clock frequency max is 14MHz (refer
- to device datasheet).
- Therefore, ADC clock prescaler must be configured in
- function of ADC clock source frequency to remain below
- this maximum frequency.
- (++) One clock setting is mandatory:
- ADC clock (core clock, also possibly conversion clock).
- (+++) Example:
- Into HAL_ADC_MspInit() (recommended code location) or with
- other device clock parameters configuration:
- (+++) RCC_PeriphCLKInitTypeDef PeriphClkInit;
- (+++) __ADC1_CLK_ENABLE();
- (+++) PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADC;
- (+++) PeriphClkInit.AdcClockSelection = RCC_ADCPCLK2_DIV2;
- (+++) HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit);
-
- (#) ADC pins configuration
- (++) Enable the clock for the ADC GPIOs
- using macro __HAL_RCC_GPIOx_CLK_ENABLE()
- (++) Configure these ADC pins in analog mode
- using function HAL_GPIO_Init()
-
- (#) Optionally, in case of usage of ADC with interruptions:
- (++) Configure the NVIC for ADC
- using function HAL_NVIC_EnableIRQ(ADCx_IRQn)
- (++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
- into the function of corresponding ADC interruption vector
- ADCx_IRQHandler().
-
- (#) Optionally, in case of usage of DMA:
- (++) Configure the DMA (DMA channel, mode normal or circular, ...)
- using function HAL_DMA_Init().
- (++) Configure the NVIC for DMA
- using function HAL_NVIC_EnableIRQ(DMAx_Channelx_IRQn)
- (++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
- into the function of corresponding DMA interruption vector
- DMAx_Channelx_IRQHandler().
-
- *** Configuration of ADC, groups regular/injected, channels parameters ***
- ==========================================================================
- [..]
-
- (#) Configure the ADC parameters (resolution, data alignment, ...)

- *** Deinitialization of ADC ***
- ============================================================
- [..]
-
- (#) Disable the ADC interface
- (++) ADC clock can be hard reset and disabled at RCC top level.
- (++) Hard reset of ADC peripherals
- using macro __ADCx_FORCE_RESET(), __ADCx_RELEASE_RESET().
- (++) ADC clock disable
- using the equivalent macro/functions as configuration step.
- (+++) Example:
- Into HAL_ADC_MspDeInit() (recommended code location) or with
- other device clock parameters configuration:
- (+++) PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADC
- (+++) PeriphClkInit.AdcClockSelection = RCC_ADCPLLCLK2_OFF
- (+++) HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit)
-
- (#) ADC pins configuration
- (++) Disable the clock for the ADC GPIOs
- using macro __HAL_RCC_GPIOx_CLK_DISABLE()
-
- (#) Optionally, in case of usage of ADC with interruptions:
- (++) Disable the NVIC for ADC
- using function HAL_NVIC_EnableIRQ(ADCx_IRQn)
-
- (#) Optionally, in case of usage of DMA:
- (++) Deinitialize the DMA
- using function HAL_DMA_Init().
- (++) Disable the NVIC for DMA
- using function HAL_NVIC_EnableIRQ(DMAx_Channelx_IRQn)
-
- [..]
-
- *** Callback registration ***
- =============================================
- [..]
-
- The compilation flag USE_HAL_ADC_REGISTER_CALLBACKS, when set to 1,
- allows the user to configure dynamically the driver callbacks.
- Use Functions @ref HAL_ADC_RegisterCallback()
- to register an interrupt callback.
- [..]
-
- Function @ref HAL_ADC_RegisterCallback() allows to register following callbacks:
- (+) ConvCpltCallback : ADC conversion complete callback
- (+) ConvHalfCpltCallback : ADC conversion DMA half-transfer callback
- (+) LevelOutOfWindowCallback : ADC analog watchdog 1 callback
- (+) ErrorCallback : ADC error callback
- (+) InjectedConvCpltCallback : ADC group injected conversion complete callback
- (+) MspInitCallback : ADC Msp Init callback
- (+) MspDeInitCallback : ADC Msp DeInit callback
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
- [..]
-
- Use function @ref HAL_ADC_UnRegisterCallback to reset a callback to the default
- weak function.
- [..]
-
- @ref HAL_ADC_UnRegisterCallback takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) ConvCpltCallback : ADC conversion complete callback
- (+) ConvHalfCpltCallback : ADC conversion DMA half-transfer callback
- (+) LevelOutOfWindowCallback : ADC analog watchdog 1 callback
- (+) ErrorCallback : ADC error callback
- (+) InjectedConvCpltCallback : ADC group injected conversion complete callback
- (+) MspInitCallback : ADC Msp Init callback
- (+) MspDeInitCallback : ADC Msp DeInit callback
- [..]
-
- By default, after the @ref HAL_ADC_Init() and when the state is @ref HAL_ADC_STATE_RESET
- all callbacks are set to the corresponding weak functions:
- examples @ref HAL_ADC_ConvCpltCallback(), @ref HAL_ADC_ErrorCallback().
- Exception done for MspInit and MspDeInit functions that are
- reset to the legacy weak functions in the @ref HAL_ADC_Init()/ @ref HAL_ADC_DeInit() only when
- these callbacks are null (not registered beforehand).
- [..]
-
- If MspInit or MspDeInit are not null, the @ref HAL_ADC_Init()/ @ref HAL_ADC_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
- [..]
-
- Callbacks can be registered/unregistered in @ref HAL_ADC_STATE_READY state only.
- Exception done MspInit/MspDeInit functions that can be registered/unregistered
- in @ref HAL_ADC_STATE_READY or @ref HAL_ADC_STATE_RESET state,
- thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
- [..]
-
- Then, the user first registers the MspInit/MspDeInit user callbacks
- using @ref HAL_ADC_RegisterCallback() before calling @ref HAL_ADC_DeInit()
- or @ref HAL_ADC_Init() function.
- [..]
-
- When the compilation flag USE_HAL_ADC_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available and all callbacks
- are set to the corresponding weak functions.

- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Initialize the CAN low level resources by implementing the
- HAL_CAN_MspInit():
- (++) Enable the CAN interface clock using __HAL_RCC_CANx_CLK_ENABLE()
- (++) Configure CAN pins
- (+++) Enable the clock for the CAN GPIOs
- (+++) Configure CAN pins as alternate function open-drain
- (++) In case of using interrupts (e.g. HAL_CAN_ActivateNotification())
- (+++) Configure the CAN interrupt priority using
- HAL_NVIC_SetPriority()
- (+++) Enable the CAN IRQ handler using HAL_NVIC_EnableIRQ()
- (+++) In CAN IRQ handler, call HAL_CAN_IRQHandler()
-
- (#) Initialize the CAN peripheral using HAL_CAN_Init() function. This
- function resorts to HAL_CAN_MspInit() for low-level initialization.
-
- (#) Configure the reception filters using the following configuration
- functions:
- (++) HAL_CAN_ConfigFilter()
-
- (#) Start the CAN module using HAL_CAN_Start() function. At this level
- the node is active on the bus: it receive messages, and can send
- messages.
-
- (#) To manage messages transmission, the following Tx control functions
- can be used:
- (++) HAL_CAN_AddTxMessage() to request transmission of a new
- message.
- (++) HAL_CAN_AbortTxRequest() to abort transmission of a pending
- message.
- (++) HAL_CAN_GetTxMailboxesFreeLevel() to get the number of free Tx
- mailboxes.
- (++) HAL_CAN_IsTxMessagePending() to check if a message is pending
- in a Tx mailbox.
- (++) HAL_CAN_GetTxTimestamp() to get the timestamp of Tx message
- sent, if time triggered communication mode is enabled.
-
- (#) When a message is received into the CAN Rx FIFOs, it can be retrieved
- using the HAL_CAN_GetRxMessage() function. The function
- HAL_CAN_GetRxFifoFillLevel() allows to know how many Rx message are
- stored in the Rx Fifo.
-
- (#) Calling the HAL_CAN_Stop() function stops the CAN module.
-
- (#) The deinitialization is achieved with HAL_CAN_DeInit() function.
-
-
- *** Polling mode operation ***
- ==============================
- [..]
- (#) Reception:
- (++) Monitor reception of message using HAL_CAN_GetRxFifoFillLevel()
- until at least one message is received.
- (++) Then get the message using HAL_CAN_GetRxMessage().
-
- (#) Transmission:
- (++) Monitor the Tx mailboxes availability until at least one Tx
- mailbox is free, using HAL_CAN_GetTxMailboxesFreeLevel().
- (++) Then request transmission of a message using
- HAL_CAN_AddTxMessage().
-
-
- *** Interrupt mode operation ***
- ================================
- [..]
- (#) Notifications are activated using HAL_CAN_ActivateNotification()
- function. Then, the process can be controlled through the
- available user callbacks: HAL_CAN_xxxCallback(), using same APIs
- HAL_CAN_GetRxMessage() and HAL_CAN_AddTxMessage().
-
- (#) Notifications can be deactivated using
- HAL_CAN_DeactivateNotification() function.
-
- (#) Special care should be taken for CAN_IT_RX_FIFO0_MSG_PENDING and
- CAN_IT_RX_FIFO1_MSG_PENDING notifications. These notifications trig
- the callbacks HAL_CAN_RxFIFO0MsgPendingCallback() and
- HAL_CAN_RxFIFO1MsgPendingCallback(). User has two possible options
- here.
- (++) Directly get the Rx message in the callback, using
- HAL_CAN_GetRxMessage().
- (++) Or deactivate the notification in the callback without
- getting the Rx message. The Rx message can then be got later
- using HAL_CAN_GetRxMessage(). Once the Rx message have been
- read, the notification can be activated again.
-
-
- *** Sleep mode ***
- ==================
- [..]
- (#) The CAN peripheral can be put in sleep mode (low power), using
- HAL_CAN_RequestSleep(). The sleep mode will be entered as soon as the
- current CAN activity (transmission or reception of a CAN frame) will
- be completed.
-
- (#) A notification can be activated to be informed when the sleep mode
- will be entered.
-
- (#) It can be checked if the sleep mode is entered using
- HAL_CAN_IsSleepActive().
- Note that the CAN state (accessible from the API HAL_CAN_GetState())
- is HAL_CAN_STATE_SLEEP_PENDING as soon as the sleep mode request is
- submitted (the sleep mode is not yet entered), and become
- HAL_CAN_STATE_SLEEP_ACTIVE when the sleep mode is effective.
-
- (#) The wake-up from sleep mode can be trigged by two ways:
- (++) Using HAL_CAN_WakeUp(). When returning from this function,
- the sleep mode is exited (if return status is HAL_OK).
- (++) When a start of Rx CAN frame is detected by the CAN peripheral,
- if automatic wake up mode is enabled.
-
- *** Callback registration ***
- =============================================
-
- The compilation define USE_HAL_CAN_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
- Use Function @ref HAL_CAN_RegisterCallback() to register an interrupt callback.
-
- Function @ref HAL_CAN_RegisterCallback() allows to register following callbacks:
- (+) TxMailbox0CompleteCallback : Tx Mailbox 0 Complete Callback.
- (+) TxMailbox1CompleteCallback : Tx Mailbox 1 Complete Callback.
- (+) TxMailbox2CompleteCallback : Tx Mailbox 2 Complete Callback.
- (+) TxMailbox0AbortCallback : Tx Mailbox 0 Abort Callback.
- (+) TxMailbox1AbortCallback : Tx Mailbox 1 Abort Callback.
- (+) TxMailbox2AbortCallback : Tx Mailbox 2 Abort Callback.
- (+) RxFifo0MsgPendingCallback : Rx Fifo 0 Message Pending Callback.
- (+) RxFifo0FullCallback : Rx Fifo 0 Full Callback.
- (+) RxFifo1MsgPendingCallback : Rx Fifo 1 Message Pending Callback.
- (+) RxFifo1FullCallback : Rx Fifo 1 Full Callback.
- (+) SleepCallback : Sleep Callback.
- (+) WakeUpFromRxMsgCallback : Wake Up From Rx Message Callback.
- (+) ErrorCallback : Error Callback.
- (+) MspInitCallback : CAN MspInit.
- (+) MspDeInitCallback : CAN MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- Use function @ref HAL_CAN_UnRegisterCallback() to reset a callback to the default
- weak function.
- @ref HAL_CAN_UnRegisterCallback takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) TxMailbox0CompleteCallback : Tx Mailbox 0 Complete Callback.
- (+) TxMailbox1CompleteCallback : Tx Mailbox 1 Complete Callback.
- (+) TxMailbox2CompleteCallback : Tx Mailbox 2 Complete Callback.
- (+) TxMailbox0AbortCallback : Tx Mailbox 0 Abort Callback.
- (+) TxMailbox1AbortCallback : Tx Mailbox 1 Abort Callback.
- (+) TxMailbox2AbortCallback : Tx Mailbox 2 Abort Callback.
- (+) RxFifo0MsgPendingCallback : Rx Fifo 0 Message Pending Callback.
- (+) RxFifo0FullCallback : Rx Fifo 0 Full Callback.
- (+) RxFifo1MsgPendingCallback : Rx Fifo 1 Message Pending Callback.
- (+) RxFifo1FullCallback : Rx Fifo 1 Full Callback.
- (+) SleepCallback : Sleep Callback.
- (+) WakeUpFromRxMsgCallback : Wake Up From Rx Message Callback.
- (+) ErrorCallback : Error Callback.
- (+) MspInitCallback : CAN MspInit.
- (+) MspDeInitCallback : CAN MspDeInit.
-
- By default, after the @ref HAL_CAN_Init() and when the state is HAL_CAN_STATE_RESET,
- all callbacks are set to the corresponding weak functions:
- example @ref HAL_CAN_ErrorCallback().
- Exception done for MspInit and MspDeInit functions that are
- reset to the legacy weak function in the @ref HAL_CAN_Init()/ @ref HAL_CAN_DeInit() only when
- these callbacks are null (not registered beforehand).
- if not, MspInit or MspDeInit are not null, the @ref HAL_CAN_Init()/ @ref HAL_CAN_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
-
- Callbacks can be registered/unregistered in HAL_CAN_STATE_READY state only.
- Exception done MspInit/MspDeInit that can be registered/unregistered
- in HAL_CAN_STATE_READY or HAL_CAN_STATE_RESET state,
- thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_CAN_RegisterCallback() before calling @ref HAL_CAN_DeInit()
- or @ref HAL_CAN_Init() function.
-
- When The compilation define USE_HAL_CAN_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available and all callbacks
- are set to the corresponding weak functions.

- * + Initialization and de-initialization function
- * + IO operation function
- * + Peripheral Control function
- *

- @verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The CEC HAL driver can be used as follow:
-
- (#) Declare a CEC_HandleTypeDef handle structure.
- (#) Initialize the CEC low level resources by implementing the HAL_CEC_MspInit ()API:
- (##) Enable the CEC interface clock.
- (##) CEC pins configuration:
- (+++) Enable the clock for the CEC GPIOs.
- (+++) Configure these CEC pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_CEC_Transmit_IT()
- and HAL_CEC_Receive_IT() APIs):
- (+++) Configure the CEC interrupt priority.
- (+++) Enable the NVIC CEC IRQ handle.
- (+++) The specific CEC interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_CEC_ENABLE_IT() and __HAL_CEC_DISABLE_IT() inside the transmit
- and receive process.
-
- (#) Program the Bit Timing Error Mode and the Bit Period Error Mode in the hcec Init structure.
-
- (#) Initialize the CEC registers by calling the HAL_CEC_Init() API.
-
- [..]
- (@) This API (HAL_CEC_Init()) configures also the low level Hardware (GPIO, CLOCK, CORTEX...etc)
- by calling the customed HAL_CEC_MspInit() API.
- *** Callback registration ***
- =============================================
- The compilation define USE_HAL_CEC_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
- Use Functions @ref HAL_CEC_RegisterCallback() or HAL_CEC_RegisterXXXCallback()
- to register an interrupt callback.
-
- Function @ref HAL_CEC_RegisterCallback() allows to register following callbacks:
- (+) TxCpltCallback : Tx Transfer completed callback.
- (+) ErrorCallback : callback for error detection.
- (+) MspInitCallback : CEC MspInit.
- (+) MspDeInitCallback : CEC MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- For specific callback HAL_CEC_RxCpltCallback use dedicated register callbacks
- @ref HAL_CEC_RegisterRxCpltCallback().
-
- Use function @ref HAL_CEC_UnRegisterCallback() to reset a callback to the default
- weak function.
- @ref HAL_CEC_UnRegisterCallback() takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) TxCpltCallback : Tx Transfer completed callback.
- (+) ErrorCallback : callback for error detection.
- (+) MspInitCallback : CEC MspInit.
- (+) MspDeInitCallback : CEC MspDeInit.
-
- For callback HAL_CEC_RxCpltCallback use dedicated unregister callback :
- @ref HAL_CEC_UnRegisterRxCpltCallback().
-
- By default, after the @ref HAL_CEC_Init() and when the state is HAL_CEC_STATE_RESET
- all callbacks are set to the corresponding weak functions :
- examples @ref HAL_CEC_TxCpltCallback() , @ref HAL_CEC_RxCpltCallback().
- Exception done for MspInit and MspDeInit functions that are
- reset to the legacy weak function in the @ref HAL_CEC_Init()/ @ref HAL_CEC_DeInit() only when
- these callbacks are null (not registered beforehand).
- if not, MspInit or MspDeInit are not null, the @ref HAL_CEC_Init() / @ref HAL_CEC_DeInit()
- keep and use the user MspInit/MspDeInit functions (registered beforehand)
-
- Callbacks can be registered/unregistered in HAL_CEC_STATE_READY state only.
- Exception done MspInit/MspDeInit callbacks that can be registered/unregistered
- in HAL_CEC_STATE_READY or HAL_CEC_STATE_RESET state,
- thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_CEC_RegisterCallback() before calling @ref HAL_CEC_DeInit()
- or @ref HAL_CEC_Init() function.
-
- When the compilation define USE_HAL_CEC_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available and all callbacks
- are set to the corresponding weak functions.

- * + Peripheral Control functions

- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
-
- [..]
- *** How to configure Interrupts using CORTEX HAL driver ***
- ===========================================================
- [..]
- This section provides functions allowing to configure the NVIC interrupts (IRQ).
- The Cortex-M3 exceptions are managed by CMSIS functions.
-
- (#) Configure the NVIC Priority Grouping using HAL_NVIC_SetPriorityGrouping()
- function according to the following table.
- (#) Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority().
- (#) Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ().
- (#) please refer to programming manual for details in how to configure priority.
-
- -@- When the NVIC_PRIORITYGROUP_0 is selected, IRQ preemption is no more possible.
- The pending IRQ priority will be managed only by the sub priority.
-
- -@- IRQ priority order (sorted by highest to lowest priority):
- (+@) Lowest preemption priority
- (+@) Lowest sub priority
- (+@) Lowest hardware priority (IRQ number)
-
- [..]
- *** How to configure Systick using CORTEX HAL driver ***
- ========================================================
- [..]
- Setup SysTick Timer for time base.
-
- (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
- is a CMSIS function that:
- (++) Configures the SysTick Reload register with value passed as function parameter.
- (++) Configures the SysTick IRQ priority to the lowest value 0x0F.
- (++) Resets the SysTick Counter register.
- (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
- (++) Enables the SysTick Interrupt.
- (++) Starts the SysTick Counter.
-
- (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
- __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
- HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
- inside the stm32f1xx_hal_cortex.h file.
-
- (+) You can change the SysTick IRQ priority by calling the
- HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
- call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
-
- (+) To adjust the SysTick time base, use the following formula:
-
- Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
- (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
- (++) Reload Value should not exceed 0xFFFFFF

- @verbatim
- ==============================================================================
- ##### DAC Peripheral features #####
- ==============================================================================
- [..]
- *** DAC Channels ***
- ====================
- [..]
- STM32F1 devices integrate two 12-bit Digital Analog Converters
-
- The 2 converters (i.e. channel1 & channel2)
- can be used independently or simultaneously (dual mode):
- (#) DAC channel1 with DAC_OUT1 (PA4) as output or connected to on-chip
- peripherals (ex. timers).
- (#) DAC channel2 with DAC_OUT2 (PA5) as output or connected to on-chip
- peripherals (ex. timers).
-
- *** DAC Triggers ***
- ====================
- [..]
- Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
- and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
- [..]
- Digital to Analog conversion can be triggered by:
- (#) External event: EXTI Line 9 (any GPIOx_PIN_9) using DAC_TRIGGER_EXT_IT9.
- The used pin (GPIOx_PIN_9) must be configured in input mode.
-
- (#) Timers TRGO: TIM2, TIM4, TIM6, TIM7
- For STM32F10x connectivity line devices and STM32F100x devices: TIM3
- For STM32F10x high-density and XL-density devices: TIM8
- For STM32F100x high-density value line devices: TIM15 as
- replacement of TIM5.
- (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T4_TRGO...)
-
- (#) Software using DAC_TRIGGER_SOFTWARE
-
- *** DAC Buffer mode feature ***
- ===============================
- [..]
- Each DAC channel integrates an output buffer that can be used to
- reduce the output impedance, and to drive external loads directly
- without having to add an external operational amplifier.
- To enable, the output buffer use
- sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
- [..]
- (@) Refer to the device datasheet for more details about output
- impedance value with and without output buffer.
-
- *** DAC connect feature ***
- ===============================
- [..]
- Each DAC channel can be connected internally.
- To connect, use
- sConfig.DAC_ConnectOnChipPeripheral = DAC_CHIPCONNECT_ENABLE;
-
- *** GPIO configurations guidelines ***
- =====================
- [..]
- When a DAC channel is used (ex channel1 on PA4) and the other is not
- (ex channel2 on PA5 is configured in Analog and disabled).
- Channel1 may disturb channel2 as coupling effect.
- Note that there is no coupling on channel2 as soon as channel2 is turned on.
- Coupling on adjacent channel could be avoided as follows:
- when unused PA5 is configured as INPUT PULL-UP or DOWN.
- PA5 is configured in ANALOG just before it is turned on.
-
- *** DAC wave generation feature ***
- ===================================
- [..]
- Both DAC channels can be used to generate
- (#) Noise wave
- (#) Triangle wave
-
- *** DAC data format ***
- =======================
- [..]
- The DAC data format can be:
- (#) 8-bit right alignment using DAC_ALIGN_8B_R
- (#) 12-bit left alignment using DAC_ALIGN_12B_L
- (#) 12-bit right alignment using DAC_ALIGN_12B_R
-
- *** DAC data value to voltage correspondence ***
- ================================================
- [..]
- The analog output voltage on each DAC channel pin is determined
- by the following equation:
- [..]
- DAC_OUTx = VREF+ * DOR / 4095
- (+) with DOR is the Data Output Register
- [..]
- VEF+ is the input voltage reference (refer to the device datasheet)
- [..]
- e.g. To set DAC_OUT1 to 0.7V, use
- (+) Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
-
- *** DMA requests ***
- =====================
- [..]
- A DMA request can be generated when an external trigger (but not a software trigger)
- occurs if DMA1 requests are enabled using HAL_DAC_Start_DMA().
- DMA1 requests are mapped as following:
- (#) DAC channel1 mapped on DMA1 channel3
- for STM32F100x low-density, medium-density, high-density with DAC
- DMA remap:
- (#) DAC channel2 mapped on DMA2 channel3
- for STM32F100x high-density without DAC DMA remap and other
- STM32F1 devices

- [..]
- (@) For Dual mode and specific signal (Triangle and noise) generation please
- refer to Extended Features Driver description
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (+) DAC APB clock must be enabled to get write access to DAC
- registers using HAL_DAC_Init()
- (+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
- (+) Configure the DAC channel using HAL_DAC_ConfigChannel() function.
- (+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA() functions.
-
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Start the DAC peripheral using HAL_DAC_Start()
- (+) To read the DAC last data output value, use the HAL_DAC_GetValue() function.
- (+) Stop the DAC peripheral using HAL_DAC_Stop()
-
- *** DMA mode IO operation ***
- ==============================
- [..]
- (+) Start the DAC peripheral using HAL_DAC_Start_DMA(), at this stage the user specify the length
- of data to be transferred at each end of conversion
- First issued trigger will start the conversion of the value previously set by HAL_DAC_SetValue().
- (+) At the middle of data transfer HAL_DAC_ConvHalfCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
- function is executed and user can add his own code by customization of function pointer
- HAL_DAC_ConvHalfCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
- (+) At The end of data transfer HAL_DAC_ConvCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
- function is executed and user can add his own code by customization of function pointer
- HAL_DAC_ConvCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
- (+) In case of transfer Error, HAL_DAC_ErrorCallbackCh1() function is executed and user can
- add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1
- (+) For STM32F100x devices with specific feature: DMA underrun.
- In case of DMA underrun, DAC interruption triggers and execute internal function HAL_DAC_IRQHandler.
- HAL_DAC_DMAUnderrunCallbackCh1() or HAL_DACEx_DMAUnderrunCallbackCh2()
- function is executed and user can add his own code by customization of function pointer
- HAL_DAC_DMAUnderrunCallbackCh1() or HAL_DACEx_DMAUnderrunCallbackCh2() and
- add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1()
- (+) Stop the DAC peripheral using HAL_DAC_Stop_DMA()
-
- *** Callback registration ***
- =============================================
- [..]
- The compilation define USE_HAL_DAC_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- Use Functions @ref HAL_DAC_RegisterCallback() to register a user callback,
- it allows to register following callbacks:
- (+) ConvCpltCallbackCh1 : callback when a half transfer is completed on Ch1.
- (+) ConvHalfCpltCallbackCh1 : callback when a transfer is completed on Ch1.
- (+) ErrorCallbackCh1 : callback when an error occurs on Ch1.
- (+) DMAUnderrunCallbackCh1 : callback when an underrun error occurs on Ch1.
- (+) ConvCpltCallbackCh2 : callback when a half transfer is completed on Ch2.
- (+) ConvHalfCpltCallbackCh2 : callback when a transfer is completed on Ch2.
- (+) ErrorCallbackCh2 : callback when an error occurs on Ch2.
- (+) DMAUnderrunCallbackCh2 : callback when an underrun error occurs on Ch2.
- (+) MspInitCallback : DAC MspInit.
- (+) MspDeInitCallback : DAC MspdeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- Use function @ref HAL_DAC_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function. It allows to reset following callbacks:
- (+) ConvCpltCallbackCh1 : callback when a half transfer is completed on Ch1.
- (+) ConvHalfCpltCallbackCh1 : callback when a transfer is completed on Ch1.
- (+) ErrorCallbackCh1 : callback when an error occurs on Ch1.
- (+) DMAUnderrunCallbackCh1 : callback when an underrun error occurs on Ch1.
- (+) ConvCpltCallbackCh2 : callback when a half transfer is completed on Ch2.
- (+) ConvHalfCpltCallbackCh2 : callback when a transfer is completed on Ch2.
- (+) ErrorCallbackCh2 : callback when an error occurs on Ch2.
- (+) DMAUnderrunCallbackCh2 : callback when an underrun error occurs on Ch2.
- (+) MspInitCallback : DAC MspInit.
- (+) MspDeInitCallback : DAC MspdeInit.
- (+) All Callbacks
- This function) takes as parameters the HAL peripheral handle and the Callback ID.
-
- By default, after the @ref HAL_DAC_Init and if the state is HAL_DAC_STATE_RESET
- all callbacks are reset to the corresponding legacy weak (surcharged) functions.
- Exception done for MspInit and MspDeInit callbacks that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_DAC_Init
- and @ref HAL_DAC_DeInit only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_DAC_Init and @ref HAL_DAC_DeInit
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
-
- Callbacks can be registered/unregistered in READY state only.
- Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
- in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
- during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_DAC_RegisterCallback before calling @ref HAL_DAC_DeInit
- or @ref HAL_DAC_Init function.
-
- When The compilation define USE_HAL_DAC_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.
-
- *** DAC HAL driver macros list ***
- =============================================
- [..]
- Below the list of most used macros in DAC HAL driver.
-
- (+) __HAL_DAC_ENABLE : Enable the DAC peripheral (For STM32F100x devices with specific feature: DMA underrun)
- (+) __HAL_DAC_DISABLE : Disable the DAC peripheral (For STM32F100x devices with specific feature: DMA underrun)
- (+) __HAL_DAC_CLEAR_FLAG: Clear the DAC's pending flags (For STM32F100x devices with specific feature: DMA underrun)
- (+) __HAL_DAC_GET_FLAG: Get the selected DAC's flag status (For STM32F100x devices with specific feature: DMA underrun)
-
- [..]

- ==============================================================================
- [..]
- *** Dual mode IO operation ***
- ==============================
- (+) When Dual mode is enabled (i.e. DAC Channel1 and Channel2 are used simultaneously) :
- Use HAL_DACEx_DualGetValue() to get digital data to be converted and use
- HAL_DACEx_DualSetValue() to set digital value to converted simultaneously in
- Channel 1 and Channel 2.
-
- *** Signal generation operation ***
- ===================================
- (+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal.
- (+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal.

- * @brief DMA HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Direct Memory Access (DMA) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral State and errors functions
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Enable and configure the peripheral to be connected to the DMA Channel
- (except for internal SRAM / FLASH memories: no initialization is
- necessary). Please refer to the Reference manual for connection between peripherals
- and DMA requests.
-
- (#) For a given Channel, program the required configuration through the following parameters:
- Channel request, Transfer Direction, Source and Destination data formats,
- Circular or Normal mode, Channel Priority level, Source and Destination Increment mode
- using HAL_DMA_Init() function.
-
- (#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error
- detection.
-
- (#) Use HAL_DMA_Abort() function to abort the current transfer
-
- -@- In Memory-to-Memory transfer mode, Circular mode is not allowed.
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source
- address and destination address and the Length of data to be transferred
- (+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this
- case a fixed Timeout can be configured by User depending from his application.
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()
- (+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ()
- (+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of
- Source address and destination address and the Length of data to be transferred.
- In this case the DMA interrupt is configured
- (+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine
- (+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can
- add his own function by customization of function pointer XferCpltCallback and
- XferErrorCallback (i.e. a member of DMA handle structure).
-
- *** DMA HAL driver macros list ***
- =============================================
- [..]
- Below the list of most used macros in DMA HAL driver.
-
- (+) __HAL_DMA_ENABLE: Enable the specified DMA Channel.
- (+) __HAL_DMA_DISABLE: Disable the specified DMA Channel.
- (+) __HAL_DMA_GET_FLAG: Get the DMA Channel pending flags.
- (+) __HAL_DMA_CLEAR_FLAG: Clear the DMA Channel pending flags.
- (+) __HAL_DMA_ENABLE_IT: Enable the specified DMA Channel interrupts.
- (+) __HAL_DMA_DISABLE_IT: Disable the specified DMA Channel interrupts.
- (+) __HAL_DMA_GET_IT_SOURCE: Check whether the specified DMA Channel interrupt has occurred or not.
-
- [..]
- (@) You can refer to the DMA HAL driver header file for more useful macros

- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#)Declare a ETH_HandleTypeDef handle structure, for example:
- ETH_HandleTypeDef heth;
-
- (#)Fill parameters of Init structure in heth handle
-
- (#)Call HAL_ETH_Init() API to initialize the Ethernet peripheral (MAC, DMA, ...)
-
- (#)Initialize the ETH low level resources through the HAL_ETH_MspInit() API:
- (##) Enable the Ethernet interface clock using
- (+++) __HAL_RCC_ETHMAC_CLK_ENABLE();
- (+++) __HAL_RCC_ETHMACTX_CLK_ENABLE();
- (+++) __HAL_RCC_ETHMACRX_CLK_ENABLE();
-
- (##) Initialize the related GPIO clocks
- (##) Configure Ethernet pin-out
- (##) Configure Ethernet NVIC interrupt (IT mode)
-
- (#)Initialize Ethernet DMA Descriptors in chain mode and point to allocated buffers:
- (##) HAL_ETH_DMATxDescListInit(); for Transmission process
- (##) HAL_ETH_DMARxDescListInit(); for Reception process
-
- (#)Enable MAC and DMA transmission and reception:
- (##) HAL_ETH_Start();
-
- (#)Prepare ETH DMA TX Descriptors and give the hand to ETH DMA to transfer
- the frame to MAC TX FIFO:
- (##) HAL_ETH_TransmitFrame();
-
- (#)Poll for a received frame in ETH RX DMA Descriptors and get received
- frame parameters
- (##) HAL_ETH_GetReceivedFrame(); (should be called into an infinite loop)
-
- (#) Get a received frame when an ETH RX interrupt occurs:
- (##) HAL_ETH_GetReceivedFrame_IT(); (called in IT mode only)
-
- (#) Communicate with external PHY device:
- (##) Read a specific register from the PHY
- HAL_ETH_ReadPHYRegister();
- (##) Write data to a specific RHY register:
- HAL_ETH_WritePHYRegister();
-
- (#) Configure the Ethernet MAC after ETH peripheral initialization
- HAL_ETH_ConfigMAC(); all MAC parameters should be filled.
-
- (#) Configure the Ethernet DMA after ETH peripheral initialization
- HAL_ETH_ConfigDMA(); all DMA parameters should be filled.
-
- -@- The PTP protocol and the DMA descriptors ring mode are not supported
- in this driver
-*** Callback registration ***
- =============================================
-
- The compilation define USE_HAL_ETH_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
- Use Function @ref HAL_ETH_RegisterCallback() to register an interrupt callback.
-
- Function @ref HAL_ETH_RegisterCallback() allows to register following callbacks:
- (+) TxCpltCallback : Tx Complete Callback.
- (+) RxCpltCallback : Rx Complete Callback.
- (+) DMAErrorCallback : DMA Error Callback.
- (+) MspInitCallback : MspInit Callback.
- (+) MspDeInitCallback: MspDeInit Callback.
-
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- Use function @ref HAL_ETH_UnRegisterCallback() to reset a callback to the default
- weak function.
- @ref HAL_ETH_UnRegisterCallback takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) TxCpltCallback : Tx Complete Callback.
- (+) RxCpltCallback : Rx Complete Callback.
- (+) DMAErrorCallback : DMA Error Callback.
- (+) MspInitCallback : MspInit Callback.
- (+) MspDeInitCallback: MspDeInit Callback.
-
- By default, after the HAL_ETH_Init and when the state is HAL_ETH_STATE_RESET
- all callbacks are set to the corresponding weak functions:
- examples @ref HAL_ETH_TxCpltCallback(), @ref HAL_ETH_RxCpltCallback().
- Exception done for MspInit and MspDeInit functions that are
- reset to the legacy weak function in the HAL_ETH_Init/ @ref HAL_ETH_DeInit only when
- these callbacks are null (not registered beforehand).
- if not, MspInit or MspDeInit are not null, the HAL_ETH_Init/ @ref HAL_ETH_DeInit
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
-
- Callbacks can be registered/unregistered in HAL_ETH_STATE_READY state only.
- Exception done MspInit/MspDeInit that can be registered/unregistered
- in HAL_ETH_STATE_READY or HAL_ETH_STATE_RESET state,
- thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_ETH_RegisterCallback() before calling @ref HAL_ETH_DeInit
- or HAL_ETH_Init function.
-
- When The compilation define USE_HAL_ETH_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available and all callbacks
- are set to the corresponding weak functions.

- @verbatim
- ==============================================================================
- ##### EXTI Peripheral features #####
- ==============================================================================
- [..]
- (+) Each Exti line can be configured within this driver.
-
- (+) Exti line can be configured in 3 different modes
- (++) Interrupt
- (++) Event
- (++) Both of them
-
- (+) Configurable Exti lines can be configured with 3 different triggers
- (++) Rising
- (++) Falling
- (++) Both of them
-
- (+) When set in interrupt mode, configurable Exti lines have two different
- interrupts pending registers which allow to distinguish which transition
- occurs:
- (++) Rising edge pending interrupt
- (++) Falling
-
- (+) Exti lines 0 to 15 are linked to gpio pin number 0 to 15. Gpio port can
- be selected through multiplexer.
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
-
- (#) Configure the EXTI line using HAL_EXTI_SetConfigLine().
- (++) Choose the interrupt line number by setting "Line" member from
- EXTI_ConfigTypeDef structure.
- (++) Configure the interrupt and/or event mode using "Mode" member from
- EXTI_ConfigTypeDef structure.
- (++) For configurable lines, configure rising and/or falling trigger
- "Trigger" member from EXTI_ConfigTypeDef structure.
- (++) For Exti lines linked to gpio, choose gpio port using "GPIOSel"
- member from GPIO_InitTypeDef structure.
-
- (#) Get current Exti configuration of a dedicated line using
- HAL_EXTI_GetConfigLine().
- (++) Provide exiting handle as parameter.
- (++) Provide pointer on EXTI_ConfigTypeDef structure as second parameter.
-
- (#) Clear Exti configuration of a dedicated line using HAL_EXTI_GetConfigLine().
- (++) Provide exiting handle as parameter.
-
- (#) Register callback to treat Exti interrupts using HAL_EXTI_RegisterCallback().
- (++) Provide exiting handle as first parameter.
- (++) Provide which callback will be registered using one value from
- EXTI_CallbackIDTypeDef.
- (++) Provide callback function pointer.
-
- (#) Get interrupt pending bit using HAL_EXTI_GetPending().
-
- (#) Clear interrupt pending bit using HAL_EXTI_GetPending().
-
- (#) Generate software interrupt using HAL_EXTI_GenerateSWI().

- * @brief FLASH HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the internal FLASH memory:
- * + Program operations functions
- * + Memory Control functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### FLASH peripheral features #####
- ==============================================================================
- [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
- to the Flash memory. It implements the erase and program Flash memory operations
- and the read and write protection mechanisms.
-
- [..] The Flash memory interface accelerates code execution with a system of instruction
- prefetch.
-
- [..] The FLASH main features are:
- (+) Flash memory read operations
- (+) Flash memory program/erase operations
- (+) Read / write protections
- (+) Prefetch on I-Code
- (+) Option Bytes programming
-
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- This driver provides functions and macros to configure and program the FLASH
- memory of all STM32F1xx devices.
-
- (#) FLASH Memory I/O Programming functions: this group includes all needed
- functions to erase and program the main memory:
- (++) Lock and Unlock the FLASH interface
- (++) Erase function: Erase page, erase all pages
- (++) Program functions: half word, word and doubleword
- (#) FLASH Option Bytes Programming functions: this group includes all needed
- functions to manage the Option Bytes:
- (++) Lock and Unlock the Option Bytes
- (++) Set/Reset the write protection
- (++) Set the Read protection Level
- (++) Program the user Option Bytes
- (++) Launch the Option Bytes loader
- (++) Erase Option Bytes
- (++) Program the data Option Bytes
- (++) Get the Write protection.
- (++) Get the user option bytes.
-
- (#) Interrupts and flags management functions : this group
- includes all needed functions to:
- (++) Handle FLASH interrupts
- (++) Wait for last FLASH operation according to its status
- (++) Get error flag status
-
- [..] In addition to these function, this driver includes a set of macros allowing
- to handle the following operations:
-
- (+) Set/Get the latency
- (+) Enable/Disable the prefetch buffer
- (+) Enable/Disable the half cycle access
- (+) Enable/Disable the FLASH interrupts
- (+) Monitor the FLASH flags status

- * @brief GPIO HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the General Purpose Input/Output (GPIO) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- *
- @verbatim
- ==============================================================================
- ##### GPIO Peripheral features #####
- ==============================================================================
- [..]
- Subject to the specific hardware characteristics of each I/O port listed in the datasheet, each
- port bit of the General Purpose IO (GPIO) Ports, can be individually configured by software
- in several modes:
- (+) Input mode
- (+) Analog mode
- (+) Output mode
- (+) Alternate function mode
- (+) External interrupt/event lines
-
- [..]
- During and just after reset, the alternate functions and external interrupt
- lines are not active and the I/O ports are configured in input floating mode.
-
- [..]
- All GPIO pins have weak internal pull-up and pull-down resistors, which can be
- activated or not.
-
- [..]
- In Output or Alternate mode, each IO can be configured on open-drain or push-pull
- type and the IO speed can be selected depending on the VDD value.
-
- [..]
- All ports have external interrupt/event capability. To use external interrupt
- lines, the port must be configured in input mode. All available GPIO pins are
- connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
-
- [..]
- The external interrupt/event controller consists of up to 20 edge detectors in connectivity
- line devices, or 19 edge detectors in other devices for generating event/interrupt requests.
- Each input line can be independently configured to select the type (event or interrupt) and
- the corresponding trigger event (rising or falling or both). Each line can also masked
- independently. A pending register maintains the status line of the interrupt requests
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Enable the GPIO APB2 clock using the following function : __HAL_RCC_GPIOx_CLK_ENABLE().
-
- (#) Configure the GPIO pin(s) using HAL_GPIO_Init().
- (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
- (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
- structure.
- (++) In case of Output or alternate function mode selection: the speed is
- configured through "Speed" member from GPIO_InitTypeDef structure
- (++) Analog mode is required when a pin is to be used as ADC channel
- or DAC output.
- (++) In case of external interrupt/event selection the "Mode" member from
- GPIO_InitTypeDef structure select the type (interrupt or event) and
- the corresponding trigger event (rising or falling or both).
-
- (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
- mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
- HAL_NVIC_EnableIRQ().
-
- (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
-
- (#) To set/reset the level of a pin configured in output mode use
- HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
-
- (#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
-
- (#) During and just after reset, the alternate functions are not
- active and the GPIO pins are configured in input floating mode (except JTAG
- pins).
-
- (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
- (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
- priority over the GPIO function.
-
- (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
- general purpose PD0 and PD1, respectively, when the HSE oscillator is off.
- The HSE has priority over the GPIO function.

- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The I2C HAL driver can be used as follows:
-
- (#) Declare a I2C_HandleTypeDef handle structure, for example:
- I2C_HandleTypeDef hi2c;
-
- (#)Initialize the I2C low level resources by implementing the @ref HAL_I2C_MspInit() API:
- (##) Enable the I2Cx interface clock
- (##) I2C pins configuration
- (+++) Enable the clock for the I2C GPIOs
- (+++) Configure I2C pins as alternate function open-drain
- (##) NVIC configuration if you need to use interrupt process
- (+++) Configure the I2Cx interrupt priority
- (+++) Enable the NVIC I2C IRQ Channel
- (##) DMA Configuration if you need to use DMA process
- (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive channel
- (+++) Enable the DMAx interface clock using
- (+++) Configure the DMA handle parameters
- (+++) Configure the DMA Tx or Rx channel
- (+++) Associate the initialized DMA handle to the hi2c DMA Tx or Rx handle
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on
- the DMA Tx or Rx channel
-
- (#) Configure the Communication Speed, Duty cycle, Addressing mode, Own Address1,
- Dual Addressing mode, Own Address2, General call and Nostretch mode in the hi2c Init structure.
-
- (#) Initialize the I2C registers by calling the @ref HAL_I2C_Init(), configures also the low level Hardware
- (GPIO, CLOCK, NVIC...etc) by calling the customized @ref HAL_I2C_MspInit() API.
-
- (#) To check if target device is ready for communication, use the function @ref HAL_I2C_IsDeviceReady()
-
- (#) For I2C IO and IO MEM operations, three operation modes are available within this driver :

- *** Interrupt mode or DMA mode IO sequential operation ***
- ==========================================================
- [..]
- (@) These interfaces allow to manage a sequential transfer with a repeated start condition
- when a direction change during transfer
- [..]
- (+) A specific option field manage the different steps of a sequential transfer
- (+) Option field values are defined through @ref I2C_XferOptions_definition and are listed below:
- (++) I2C_FIRST_AND_LAST_FRAME: No sequential usage, functionnal is same as associated interfaces in no sequential mode
- (++) I2C_FIRST_FRAME: Sequential usage, this option allow to manage a sequence with start condition, address
- and data to transfer without a final stop condition
- (++) I2C_FIRST_AND_NEXT_FRAME: Sequential usage (Master only), this option allow to manage a sequence with start condition, address
- and data to transfer without a final stop condition, an then permit a call the same master sequential interface
- several times (like @ref HAL_I2C_Master_Seq_Transmit_IT() then @ref HAL_I2C_Master_Seq_Transmit_IT()
- or @ref HAL_I2C_Master_Seq_Transmit_DMA() then @ref HAL_I2C_Master_Seq_Transmit_DMA())
- (++) I2C_NEXT_FRAME: Sequential usage, this option allow to manage a sequence with a restart condition, address
- and with new data to transfer if the direction change or manage only the new data to transfer
- if no direction change and without a final stop condition in both cases
- (++) I2C_LAST_FRAME: Sequential usage, this option allow to manage a sequance with a restart condition, address
- and with new data to transfer if the direction change or manage only the new data to transfer
- if no direction change and with a final stop condition in both cases
- (++) I2C_LAST_FRAME_NO_STOP: Sequential usage (Master only), this option allow to manage a restart condition after several call of the same master sequential
- interface several times (link with option I2C_FIRST_AND_NEXT_FRAME).
- Usage can, transfer several bytes one by one using HAL_I2C_Master_Seq_Transmit_IT(option I2C_FIRST_AND_NEXT_FRAME then I2C_NEXT_FRAME)

- or HAL_I2C_Master_Seq_Transmit_DMA(option I2C_FIRST_AND_NEXT_FRAME then I2C_NEXT_FRAME)
- or HAL_I2C_Master_Seq_Receive_DMA(option I2C_FIRST_AND_NEXT_FRAME then I2C_NEXT_FRAME).
- Then usage of this option I2C_LAST_FRAME_NO_STOP at the last Transmit or Receive sequence permit to call the oposite interface Receive or Transmit
- without stopping the communication and so generate a restart condition.
- (++) I2C_OTHER_FRAME: Sequential usage (Master only), this option allow to manage a restart condition after each call of the same master sequential
- interface.
- Usage can, transfer several bytes one by one with a restart with slave address between each bytes using HAL_I2C_Master_Seq_Transmit_IT(option I2C_FIRST_FRAME then I2C_OTHER_FRAME)
- or HAL_I2C_Master_Seq_Receive_IT(option I2C_FIRST_FRAME then I2C_OTHER_FRAME)
- or HAL_I2C_Master_Seq_Transmit_DMA(option I2C_FIRST_FRAME then I2C_OTHER_FRAME)
- or HAL_I2C_Master_Seq_Receive_DMA(option I2C_FIRST_FRAME then I2C_OTHER_FRAME).
- Then usage of this option I2C_OTHER_AND_LAST_FRAME at the last frame to help automatic generation of STOP condition.

-
- *** I2C HAL driver macros list ***
- ==================================
- [..]
- Below the list of most used macros in I2C HAL driver.
-
- (+) @ref __HAL_I2C_ENABLE: Enable the I2C peripheral
- (+) @ref __HAL_I2C_DISABLE: Disable the I2C peripheral
- (+) @ref __HAL_I2C_GET_FLAG: Checks whether the specified I2C flag is set or not
- (+) @ref __HAL_I2C_CLEAR_FLAG: Clear the specified I2C pending flag
- (+) @ref __HAL_I2C_ENABLE_IT: Enable the specified I2C interrupt
- (+) @ref __HAL_I2C_DISABLE_IT: Disable the specified I2C interrupt
-
- *** Callback registration ***
- =============================================
- [..]
- The compilation flag USE_HAL_I2C_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
- Use Functions @ref HAL_I2C_RegisterCallback() or @ref HAL_I2C_RegisterAddrCallback()
- to register an interrupt callback.
- [..]
- Function @ref HAL_I2C_RegisterCallback() allows to register following callbacks:
- (+) MasterTxCpltCallback : callback for Master transmission end of transfer.
- (+) MasterRxCpltCallback : callback for Master reception end of transfer.
- (+) SlaveTxCpltCallback : callback for Slave transmission end of transfer.
- (+) SlaveRxCpltCallback : callback for Slave reception end of transfer.
- (+) ListenCpltCallback : callback for end of listen mode.
- (+) MemTxCpltCallback : callback for Memory transmission end of transfer.
- (+) MemRxCpltCallback : callback for Memory reception end of transfer.
- (+) ErrorCallback : callback for error detection.
- (+) AbortCpltCallback : callback for abort completion process.
- (+) MspInitCallback : callback for Msp Init.
- (+) MspDeInitCallback : callback for Msp DeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
- [..]
- For specific callback AddrCallback use dedicated register callbacks : @ref HAL_I2C_RegisterAddrCallback().
- [..]
- Use function @ref HAL_I2C_UnRegisterCallback to reset a callback to the default
- weak function.
- @ref HAL_I2C_UnRegisterCallback takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) MasterTxCpltCallback : callback for Master transmission end of transfer.
- (+) MasterRxCpltCallback : callback for Master reception end of transfer.
- (+) SlaveTxCpltCallback : callback for Slave transmission end of transfer.
- (+) SlaveRxCpltCallback : callback for Slave reception end of transfer.
- (+) ListenCpltCallback : callback for end of listen mode.
- (+) MemTxCpltCallback : callback for Memory transmission end of transfer.
- (+) MemRxCpltCallback : callback for Memory reception end of transfer.
- (+) ErrorCallback : callback for error detection.
- (+) AbortCpltCallback : callback for abort completion process.
- (+) MspInitCallback : callback for Msp Init.
- (+) MspDeInitCallback : callback for Msp DeInit.
- [..]
- For callback AddrCallback use dedicated register callbacks : @ref HAL_I2C_UnRegisterAddrCallback().
- [..]
- By default, after the @ref HAL_I2C_Init() and when the state is @ref HAL_I2C_STATE_RESET
- all callbacks are set to the corresponding weak functions:
- examples @ref HAL_I2C_MasterTxCpltCallback(), @ref HAL_I2C_MasterRxCpltCallback().
- Exception done for MspInit and MspDeInit functions that are
- reset to the legacy weak functions in the @ref HAL_I2C_Init()/ @ref HAL_I2C_DeInit() only when
- these callbacks are null (not registered beforehand).
- If MspInit or MspDeInit are not null, the @ref HAL_I2C_Init()/ @ref HAL_I2C_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
- [..]
- Callbacks can be registered/unregistered in @ref HAL_I2C_STATE_READY state only.
- Exception done MspInit/MspDeInit functions that can be registered/unregistered
- in @ref HAL_I2C_STATE_READY or @ref HAL_I2C_STATE_RESET state,
- thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
- Then, the user first registers the MspInit/MspDeInit user callbacks
- using @ref HAL_I2C_RegisterCallback() before calling @ref HAL_I2C_DeInit()
- or @ref HAL_I2C_Init() function.
- [..]
- When the compilation flag USE_HAL_I2C_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available and all callbacks
- are set to the corresponding weak functions.
-
-
- *** I2C Workarounds linked to Silicon Limitation ***
- ====================================================
- [..]
- Below the list of all silicon limitations implemented for HAL on STM32F1xx product.
- (@) See ErrataSheet to know full silicon limitation list of your product.
-
- (+) Workarounds Implemented inside I2C HAL Driver
- (++) Wrong data read into data register (Polling and Interrupt mode)
- (++) Start cannot be generated after a misplaced Stop
- (++) Some software events must be managed before the current byte is being transferred:
- Workaround: Use DMA in general, except when the Master is receiving a single byte.
- For Interupt mode, I2C should have the highest priority in the application.
- (++) Mismatch on the "Setup time for a repeated Start condition" timing parameter:
- Workaround: Reduce the frequency down to 88 kHz or use the I2C Fast-mode if
- supported by the slave.
- (++) Data valid time (tVD;DAT) violated without the OVR flag being set:
- Workaround: If the slave device allows it, use the clock stretching mechanism
- by programming NoStretchMode = I2C_NOSTRETCH_DISABLE in @ref HAL_I2C_Init.
-
- [..]
- (@) You can refer to the I2C HAL driver header file for more useful macros

- This subsection provides a set of functions allowing to manage the I2C data
- transfers.
-
- (#) There are two modes of transfer:
- (++) Blocking mode : The communication is performed in the polling mode.
- The status of all data processing is returned by the same function
- after finishing transfer.
- (++) No-Blocking mode : The communication is performed using Interrupts
- or DMA. These functions return the status of the transfer startup.
- The end of the data processing will be indicated through the
- dedicated I2C IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
-
- (#) Blocking mode functions are :
- (++) HAL_I2C_Master_Transmit()
- (++) HAL_I2C_Master_Receive()
- (++) HAL_I2C_Slave_Transmit()
- (++) HAL_I2C_Slave_Receive()
- (++) HAL_I2C_Mem_Write()
- (++) HAL_I2C_Mem_Read()
- (++) HAL_I2C_IsDeviceReady()
-
- (#) No-Blocking mode functions with Interrupt are :
- (++) HAL_I2C_Master_Transmit_IT()
- (++) HAL_I2C_Master_Receive_IT()
- (++) HAL_I2C_Slave_Transmit_IT()
- (++) HAL_I2C_Slave_Receive_IT()

- (++) HAL_I2C_EnableListen_IT()
- (++) HAL_I2C_DisableListen_IT()
- (++) HAL_I2C_Master_Abort_IT()

- * This file provides firmware functions to manage the following

- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral State and Errors functions
- @verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- The I2S HAL driver can be used as follow:
-
- (#) Declare a I2S_HandleTypeDef handle structure.
- (#) Initialize the I2S low level resources by implement the HAL_I2S_MspInit() API:
- (##) Enable the SPIx interface clock.
- (##) I2S pins configuration:
- (+++) Enable the clock for the I2S GPIOs.
- (+++) Configure these I2S pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_I2S_Transmit_IT()
- and HAL_I2S_Receive_IT() APIs).
- (+++) Configure the I2Sx interrupt priority.
- (+++) Enable the NVIC I2S IRQ handle.
- (##) DMA Configuration if you need to use DMA process (HAL_I2S_Transmit_DMA()
- and HAL_I2S_Receive_DMA() APIs:
- (+++) Declare a DMA handle structure for the Tx/Rx Stream/Channel.
- (+++) Enable the DMAx interface clock.
- (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+++) Configure the DMA Tx/Rx Stream/Channel.
- (+++) Associate the initialized DMA handle to the I2S DMA Tx/Rx handle.
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the
- DMA Tx/Rx Stream/Channel.
-
- (#) Program the Mode, Standard, Data Format, MCLK Output, Audio frequency and Polarity
- using HAL_I2S_Init() function.
-
- -@- The specific I2S interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_I2S_ENABLE_IT() and __HAL_I2S_DISABLE_IT() inside the transmit and receive process.
- -@- The I2SxCLK source is the system clock (provided by the HSI, the HSE or the PLL, and sourcing the AHB clock).
- For connectivity line devices, the I2SxCLK source can be either SYSCLK or the PLL3 VCO (2 x PLL3CLK) clock
- in order to achieve the maximum accuracy.
- -@- Make sure that either:
- (+@) External clock source is configured after setting correctly
- the define constant HSE_VALUE in the stm32f1xx_hal_conf.h file.
-
- (#) Three mode of operations are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Send an amount of data in blocking mode using HAL_I2S_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_I2S_Receive()
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Send an amount of data in non blocking mode using HAL_I2S_Transmit_IT()
- (+) At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_TxHalfCpltCallback
- (+) At transmission end of transfer HAL_I2S_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_TxCpltCallback
- (+) Receive an amount of data in non blocking mode using HAL_I2S_Receive_IT()

- (+) At reception end of transfer HAL_I2S_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_RxCpltCallback
- (+) In case of transfer Error, HAL_I2S_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_I2S_ErrorCallback
-
- *** DMA mode IO operation ***
- ==============================
- [..]
- (+) Send an amount of data in non blocking mode (DMA) using HAL_I2S_Transmit_DMA()
- (+) At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_TxHalfCpltCallback
- (+) At transmission end of transfer HAL_I2S_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_TxCpltCallback
- (+) Receive an amount of data in non blocking mode (DMA) using HAL_I2S_Receive_DMA()
- (+) At reception end of half transfer HAL_I2S_RxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_RxHalfCpltCallback
- (+) At reception end of transfer HAL_I2S_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_I2S_RxCpltCallback
- (+) In case of transfer Error, HAL_I2S_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_I2S_ErrorCallback
- (+) Pause the DMA Transfer using HAL_I2S_DMAPause()
- (+) Resume the DMA Transfer using HAL_I2S_DMAResume()
- (+) Stop the DMA Transfer using HAL_I2S_DMAStop()
-
- *** I2S HAL driver macros list ***
- ===================================
- [..]
- Below the list of most used macros in I2S HAL driver.
-
- (+) __HAL_I2S_ENABLE: Enable the specified SPI peripheral (in I2S mode)
- (+) __HAL_I2S_DISABLE: Disable the specified SPI peripheral (in I2S mode)
- (+) __HAL_I2S_ENABLE_IT : Enable the specified I2S interrupts
- (+) __HAL_I2S_DISABLE_IT : Disable the specified I2S interrupts
- (+) __HAL_I2S_GET_FLAG: Check whether the specified I2S flag is set or not
-
- [..]
- (@) You can refer to the I2S HAL driver header file for more useful macros
-
- *** I2S HAL driver macros list ***
- ===================================
- [..]
- Callback registration:
-
- (#) The compilation flag USE_HAL_I2S_REGISTER_CALLBACKS when set to 1U
- allows the user to configure dynamically the driver callbacks.
- Use Functions HAL_I2S_RegisterCallback() to register an interrupt callback.
-
- Function HAL_I2S_RegisterCallback() allows to register following callbacks:
- (++) TxCpltCallback : I2S Tx Completed callback
- (++) RxCpltCallback : I2S Rx Completed callback
- (++) TxHalfCpltCallback : I2S Tx Half Completed callback
- (++) RxHalfCpltCallback : I2S Rx Half Completed callback
- (++) ErrorCallback : I2S Error callback
- (++) MspInitCallback : I2S Msp Init callback
- (++) MspDeInitCallback : I2S Msp DeInit callback
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
-
- (#) Use function HAL_I2S_UnRegisterCallback to reset a callback to the default
- weak function.
- HAL_I2S_UnRegisterCallback takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (++) TxCpltCallback : I2S Tx Completed callback
- (++) RxCpltCallback : I2S Rx Completed callback
- (++) TxHalfCpltCallback : I2S Tx Half Completed callback
- (++) RxHalfCpltCallback : I2S Rx Half Completed callback
- (++) ErrorCallback : I2S Error callback
- (++) MspInitCallback : I2S Msp Init callback
- (++) MspDeInitCallback : I2S Msp DeInit callback
-
- [..]
- By default, after the HAL_I2S_Init() and when the state is HAL_I2S_STATE_RESET
- all callbacks are set to the corresponding weak functions:
- examples HAL_I2S_MasterTxCpltCallback(), HAL_I2S_MasterRxCpltCallback().
- Exception done for MspInit and MspDeInit functions that are
- reset to the legacy weak functions in the HAL_I2S_Init()/ HAL_I2S_DeInit() only when
- these callbacks are null (not registered beforehand).
- If MspInit or MspDeInit are not null, the HAL_I2S_Init()/ HAL_I2S_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
-
- [..]
- Callbacks can be registered/unregistered in HAL_I2S_STATE_READY state only.
- Exception done MspInit/MspDeInit functions that can be registered/unregistered
- in HAL_I2S_STATE_READY or HAL_I2S_STATE_RESET state,
- thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
- Then, the user first registers the MspInit/MspDeInit user callbacks
- using HAL_I2S_RegisterCallback() before calling HAL_I2S_DeInit()
- or HAL_I2S_Init() function.
-
- [..]
- When the compilation define USE_HAL_I2S_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.
-
- *** I2S Workarounds linked to Silicon Limitation ***
- ====================================================
- [..]
- (@) Only the 16-bit mode with no data extension can be used when the I2S
- is in Master and used the PCM long synchronization mode.

- ##### IO operation functions #####

- [..]
- This subsection provides a set of functions allowing to manage the I2S data
- transfers.
-
- (#) There are two modes of transfer:
- (++) Blocking mode : The communication is performed in the polling mode.
- The status of all data processing is returned by the same function
- after finishing transfer.
- (++) No-Blocking mode : The communication is performed using Interrupts
- or DMA. These functions return the status of the transfer startup.
- The end of the data processing will be indicated through the
- dedicated I2S IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
-
- (#) Blocking mode functions are :
- (++) HAL_I2S_Transmit()
- (++) HAL_I2S_Receive()
-
- (#) No-Blocking mode functions with Interrupt are :
- (++) HAL_I2S_Transmit_IT()
- (++) HAL_I2S_Receive_IT()
-
- (#) No-Blocking mode functions with DMA are :
- (++) HAL_I2S_Transmit_DMA()
- (++) HAL_I2S_Receive_DMA()
-
- (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
- (++) HAL_I2S_TxCpltCallback()
- (++) HAL_I2S_RxCpltCallback()
- (++) HAL_I2S_ErrorCallback()

- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The IRDA HAL driver can be used as follows:
-
- (#) Declare a IRDA_HandleTypeDef handle structure (eg. IRDA_HandleTypeDef hirda).
- (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
- (##) Enable the USARTx interface clock.
- (##) IRDA pins configuration:
- (+++) Enable the clock for the IRDA GPIOs.
- (+++) Configure IRDA pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
- and HAL_IRDA_Receive_IT() APIs):
- (+++) Configure the USARTx interrupt priority.
- (+++) Enable the NVIC USART IRQ handle.
- (##) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
- and HAL_IRDA_Receive_DMA() APIs):
- (+++) Declare a DMA handle structure for the Tx/Rx channel.
- (+++) Enable the DMAx interface clock.
- (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+++) Configure the DMA Tx/Rx channel.
- (+++) Associate the initialized DMA handle to the IRDA DMA Tx/Rx handle.
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
- (+++) Configure the IRDAx interrupt priority and enable the NVIC USART IRQ handle
- (used for last byte sending completion detection in DMA non circular mode)
-
- (#) Program the Baud Rate, Word Length, Parity, IrDA Mode, Prescaler
- and Mode(Receiver/Transmitter) in the hirda Init structure.
-
- (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
- (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customized HAL_IRDA_MspInit() API.
-
- -@@- The specific IRDA interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
-
- (#) Three operation modes are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Send an amount of data in blocking mode using HAL_IRDA_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_IRDA_Receive()
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Send an amount of data in non blocking mode using HAL_IRDA_Transmit_IT()
- (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
- (+) Receive an amount of data in non blocking mode using HAL_IRDA_Receive_IT()
- (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxCpltCallback
- (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_IRDA_ErrorCallback
-
- *** DMA mode IO operation ***
- =============================
- [..]
- (+) Send an amount of data in non blocking mode (DMA) using HAL_IRDA_Transmit_DMA()
- (+) At transmission end of half transfer HAL_IRDA_TxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxHalfCpltCallback
- (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
- (+) Receive an amount of data in non blocking mode (DMA) using HAL_IRDA_Receive_DMA()
- (+) At reception end of half transfer HAL_IRDA_RxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxHalfCpltCallback
- (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_IRDA_RxCpltCallback
- (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_IRDA_ErrorCallback
- (+) Pause the DMA Transfer using HAL_IRDA_DMAPause()
- (+) Resume the DMA Transfer using HAL_IRDA_DMAResume()
- (+) Stop the DMA Transfer using HAL_IRDA_DMAStop()
-
- *** IRDA HAL driver macros list ***
- ===================================
- [..]
- Below the list of most used macros in IRDA HAL driver.
-
- (+) __HAL_IRDA_ENABLE: Enable the IRDA peripheral
- (+) __HAL_IRDA_DISABLE: Disable the IRDA peripheral
- (+) __HAL_IRDA_GET_FLAG : Check whether the specified IRDA flag is set or not
- (+) __HAL_IRDA_CLEAR_FLAG : Clear the specified IRDA pending flag
- (+) __HAL_IRDA_ENABLE_IT: Enable the specified IRDA interrupt
- (+) __HAL_IRDA_DISABLE_IT: Disable the specified IRDA interrupt
- (+) __HAL_IRDA_GET_IT_SOURCE: Check whether the specified IRDA interrupt has occurred or not
-
- [..]
- (@) You can refer to the IRDA HAL driver header file for more useful macros
-
- ##### Callback registration #####
- ==================================
-
- [..]
- The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- [..]
- Use Function @ref HAL_IRDA_RegisterCallback() to register a user callback.
- Function @ref HAL_IRDA_RegisterCallback() allows to register following callbacks:
- (+) TxHalfCpltCallback : Tx Half Complete Callback.
- (+) TxCpltCallback : Tx Complete Callback.
- (+) RxHalfCpltCallback : Rx Half Complete Callback.
- (+) RxCpltCallback : Rx Complete Callback.
- (+) ErrorCallback : Error Callback.
- (+) AbortCpltCallback : Abort Complete Callback.
- (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
- (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
- (+) MspInitCallback : IRDA MspInit.
- (+) MspDeInitCallback : IRDA MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- [..]
- Use function @ref HAL_IRDA_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function.
- @ref HAL_IRDA_UnRegisterCallback() takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) TxHalfCpltCallback : Tx Half Complete Callback.
- (+) TxCpltCallback : Tx Complete Callback.
- (+) RxHalfCpltCallback : Rx Half Complete Callback.
- (+) RxCpltCallback : Rx Complete Callback.
- (+) ErrorCallback : Error Callback.
- (+) AbortCpltCallback : Abort Complete Callback.
- (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
- (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
- (+) MspInitCallback : IRDA MspInit.
- (+) MspDeInitCallback : IRDA MspDeInit.
-
- [..]
- By default, after the @ref HAL_IRDA_Init() and when the state is HAL_IRDA_STATE_RESET
- all callbacks are set to the corresponding weak (surcharged) functions:
- examples @ref HAL_IRDA_TxCpltCallback(), @ref HAL_IRDA_RxHalfCpltCallback().
- Exception done for MspInit and MspDeInit functions that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_IRDA_Init()
- and @ref HAL_IRDA_DeInit() only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_IRDA_Init() and @ref HAL_IRDA_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
-
- [..]
- Callbacks can be registered/unregistered in HAL_IRDA_STATE_READY state only.
- Exception done MspInit/MspDeInit that can be registered/unregistered
- in HAL_IRDA_STATE_READY or HAL_IRDA_STATE_RESET state, thus registered (user)
- MspInit/DeInit callbacks can be used during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_IRDA_RegisterCallback() before calling @ref HAL_IRDA_DeInit()
- or @ref HAL_IRDA_Init() function.
-
- [..]
- When The compilation define USE_HAL_IRDA_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available
- and weak (surcharged) callbacks are used.
-
- @endverbatim
- [..]
- (@) Additionnal remark: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits),
- the possible IRDA frame formats are as listed in the following table:
- +-------------------------------------------------------------+
- | M bit | PCE bit | IRDA frame |
- |---------------------|---------------------------------------|
- | 0 | 0 | | SB | 8 bit data | 1 STB | |
- |---------|-----------|---------------------------------------|
- | 0 | 1 | | SB | 7 bit data | PB | 1 STB | |
- |---------|-----------|---------------------------------------|
- | 1 | 0 | | SB | 9 bit data | 1 STB | |
- |---------|-----------|---------------------------------------|
- | 1 | 1 | | SB | 8 bit data | PB | 1 STB | |
- +-------------------------------------------------------------+

- ##### Initialization and Configuration functions #####
- ==============================================================================
- [..]
- This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
- in asynchronous IrDA mode.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) BaudRate
- (++) WordLength
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits),
- please refer to Reference manual for possible IRDA frame formats.
- (++) Prescaler: A pulse of width less than two and greater than one PSC period(s) may or may
- not be rejected. The receiver set up time should be managed by software. The IrDA physical layer
- specification specifies a minimum of 10 ms delay between transmission and
- reception (IrDA is a half duplex protocol).
- (++) Mode: Receiver/transmitter modes
- (++) IrDAMode: the IrDA can operate in the Normal mode or in the Low power mode.
- [..]
- The HAL_IRDA_Init() API follows IRDA configuration procedures (details for the procedures
- are available in reference manual).

- * @brief IRDA Transmit and Receive functions
- *
-@verbatim
- ==============================================================================
- ##### IO operation functions #####
- ==============================================================================
- [..]
- This subsection provides a set of functions allowing to manage the IRDA data transfers.
- IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
- on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
- is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
- While receiving data, transmission should be avoided as the data to be transmitted
- could be corrupted.
-
- (#) There are two modes of transfer:
- (++) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (++) Non-Blocking mode: The communication is performed using Interrupts
- or DMA, these API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
- will be executed respectively at the end of the Transmit or Receive process
- The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
-
- (#) Blocking mode APIs are :
- (++) HAL_IRDA_Transmit()
- (++) HAL_IRDA_Receive()
-
- (#) Non Blocking mode APIs with Interrupt are :
- (++) HAL_IRDA_Transmit_IT()
- (++) HAL_IRDA_Receive_IT()
- (++) HAL_IRDA_IRQHandler()
-
- (#) Non Blocking mode functions with DMA are :
- (++) HAL_IRDA_Transmit_DMA()
- (++) HAL_IRDA_Receive_DMA()
- (++) HAL_IRDA_DMAPause()
- (++) HAL_IRDA_DMAResume()
- (++) HAL_IRDA_DMAStop()
-
- (#) A set of Transfer Complete Callbacks are provided in Non Blocking mode:
- (++) HAL_IRDA_TxHalfCpltCallback()
- (++) HAL_IRDA_TxCpltCallback()
- (++) HAL_IRDA_RxHalfCpltCallback()
- (++) HAL_IRDA_RxCpltCallback()
- (++) HAL_IRDA_ErrorCallback()
-
- (#) Non-Blocking mode transfers could be aborted using Abort API's :
- (+) HAL_IRDA_Abort()
- (+) HAL_IRDA_AbortTransmit()
- (+) HAL_IRDA_AbortReceive()
- (+) HAL_IRDA_Abort_IT()
- (+) HAL_IRDA_AbortTransmit_IT()
- (+) HAL_IRDA_AbortReceive_IT()
-
- (#) For Abort services based on interrupts (HAL_IRDA_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
- (+) HAL_IRDA_AbortCpltCallback()
- (+) HAL_IRDA_AbortTransmitCpltCallback()
- (+) HAL_IRDA_AbortReceiveCpltCallback()
-
- (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
- Errors are handled as follows :
- (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
- to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
- Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
- and HAL_IRDA_ErrorCallback() user callback is executed. Transfer is kept ongoing on IRDA side.
- If user wants to abort it, Abort services should be called by user.
- (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
- This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
- Error code is set to allow user to identify error type, and HAL_IRDA_ErrorCallback() user callback is executed.

- (+) HAL_IRDA_GetState() API can be helpful to check in run-time the state of the IrDA peripheral.
- (+) HAL_IRDA_GetError() check in run-time errors that could be occurred during communication.

- * @brief IWDG HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Independent Watchdog (IWDG) peripheral:
- * + Initialization and Start functions
- * + IO operation functions
- *
- @verbatim
- ==============================================================================
- ##### IWDG Generic features #####
- ==============================================================================
- [..]
- (+) The IWDG can be started by either software or hardware (configurable
- through option byte).
-
- (+) The IWDG is clocked by Low-Speed clock (LSI) and thus stays active even
- if the main clock fails.
-
- (+) Once the IWDG is started, the LSI is forced ON and both can not be
- disabled. The counter starts counting down from the reset value (0xFFF).
- When it reaches the end of count value (0x000) a reset signal is
- generated (IWDG reset).
-
- (+) Whenever the key value 0x0000 AAAA is written in the IWDG_KR register,
- the IWDG_RLR value is reloaded in the counter and the watchdog reset is
- prevented.
-
- (+) The IWDG is implemented in the VDD voltage domain that is still functional
- in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
- IWDGRST flag in RCC_CSR register can be used to inform when an IWDG
- reset occurs.
-
- (+) Debug mode : When the microcontroller enters debug mode (core halted),
- the IWDG counter either continues to work normally or stops, depending
- on DBG_IWDG_STOP configuration bit in DBG module, accessible through
- __HAL_DBGMCU_FREEZE_IWDG() and __HAL_DBGMCU_UNFREEZE_IWDG() macros
-
- [..] Min-max timeout value @32KHz (LSI): ~125us / ~32.7s
- The IWDG timeout may vary due to LSI frequency dispersion. STM32F1xx
- devices provide the capability to measure the LSI frequency (LSI clock
- connected internally to TIM5 CH4 input capture). The measured value
- can be used to have an IWDG timeout with an acceptable accuracy.
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Use IWDG using HAL_IWDG_Init() function to :
- (++) Enable instance by writing Start keyword in IWDG_KEY register. LSI
- clock is forced ON and IWDG counter starts downcounting.
- (++) Enable write access to configuration register: IWDG_PR & IWDG_RLR.
- (++) Configure the IWDG prescaler and counter reload value. This reload
- value will be loaded in the IWDG counter each time the watchdog is
- reloaded, then the IWDG will start counting down from this value.
- (++) wait for status flags to be reset"
-
- (#) Then the application program must refresh the IWDG counter at regular
- intervals during normal operation to prevent an MCU reset, using
- HAL_IWDG_Refresh() function.
-
- *** IWDG HAL driver macros list ***
- ====================================
- [..]
- Below the list of most used macros in IWDG HAL driver:
- (+) __HAL_IWDG_START: Enable the IWDG peripheral
- (+) __HAL_IWDG_RELOAD_COUNTER: Reloads IWDG counter with value defined in
- the reload register

- ##### How to use this driver #####
- ==============================================================================
- [..]
- This driver implements a high level communication layer for read and write from/to
- this memory. The needed STM32 hardware resources (SDMMC and GPIO) are performed by
- the user in HAL_MMC_MspInit() function (MSP layer).
- Basically, the MSP layer configuration should be the same as we provide in the
- examples.
- You can easily tailor this configuration according to hardware resources.
-
- [..]
- This driver is a generic layered driver for SDMMC memories which uses the HAL
- SDMMC driver functions to interface with MMC and eMMC cards devices.
- It is used as follows:
-
- (#)Initialize the SDMMC low level resources by implement the HAL_MMC_MspInit() API:
- (##) Enable the SDMMC interface clock using __HAL_RCC_SDMMC_CLK_ENABLE();
- (##) SDMMC pins configuration for MMC card
- (+++) Enable the clock for the SDMMC GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
- (+++) Configure these SDMMC pins as alternate function pull-up using HAL_GPIO_Init()
- and according to your pin assignment;
- (##) DMA Configuration if you need to use DMA process (HAL_MMC_ReadBlocks_DMA()
- and HAL_MMC_WriteBlocks_DMA() APIs).
- (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE();
- (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled.
- (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
- (+++) Configure the SDMMC and DMA interrupt priorities using function HAL_NVIC_SetPriority();
- DMA priority is superior to SDMMC's priority
- (+++) Enable the NVIC DMA and SDMMC IRQs using function HAL_NVIC_EnableIRQ()
- (+++) SDMMC interrupts are managed using the macros __HAL_MMC_ENABLE_IT()
- and __HAL_MMC_DISABLE_IT() inside the communication process.
- (+++) SDMMC interrupts pending bits are managed using the macros __HAL_MMC_GET_IT()
- and __HAL_MMC_CLEAR_IT()
- (##) NVIC configuration if you need to use interrupt process (HAL_MMC_ReadBlocks_IT()
- and HAL_MMC_WriteBlocks_IT() APIs).
- (+++) Configure the SDMMC interrupt priorities using function HAL_NVIC_SetPriority();
- (+++) Enable the NVIC SDMMC IRQs using function HAL_NVIC_EnableIRQ()
- (+++) SDMMC interrupts are managed using the macros __HAL_MMC_ENABLE_IT()
- and __HAL_MMC_DISABLE_IT() inside the communication process.
- (+++) SDMMC interrupts pending bits are managed using the macros __HAL_MMC_GET_IT()
- and __HAL_MMC_CLEAR_IT()
- (#) At this stage, you can perform MMC read/write/erase operations after MMC card initialization
-
-
- *** MMC Card Initialization and configuration ***
- ================================================
- [..]
- To initialize the MMC Card, use the HAL_MMC_Init() function. It Initializes
- SDMMC Peripheral (STM32 side) and the MMC Card, and put it into StandBy State (Ready for data transfer).
- This function provide the following operations:
-
- (#) Initialize the SDMMC peripheral interface with defaullt configuration.
- The initialization process is done at 400KHz. You can change or adapt
- this frequency by adjusting the "ClockDiv" field.
- The MMC Card frequency (SDMMC_CK) is computed as follows:
-
- SDMMC_CK = SDMMCCLK / (ClockDiv + 2)
-
- In initialization mode and according to the MMC Card standard,
- make sure that the SDMMC_CK frequency doesn't exceed 400KHz.
-
- This phase of initialization is done through SDMMC_Init() and
- SDMMC_PowerState_ON() SDMMC low level APIs.
-
- (#) Initialize the MMC card. The API used is HAL_MMC_InitCard().
- This phase allows the card initialization and identification
- and check the MMC Card type (Standard Capacity or High Capacity)
- The initialization flow is compatible with MMC standard.
-
- This API (HAL_MMC_InitCard()) could be used also to reinitialize the card in case
- of plug-off plug-in.
-
- (#) Configure the MMC Card Data transfer frequency. By Default, the card transfer
- frequency is set to 24MHz. You can change or adapt this frequency by adjusting
- the "ClockDiv" field.
- In transfer mode and according to the MMC Card standard, make sure that the
- SDMMC_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
- To be able to use a frequency higher than 24MHz, you should use the SDMMC
- peripheral in bypass mode. Refer to the corresponding reference manual
- for more details.
-
- (#) Select the corresponding MMC Card according to the address read with the step 2.
-
- (#) Configure the MMC Card in wide bus mode: 4-bits data.
-
- *** MMC Card Read operation ***
- ==============================
- [..]
- (+) You can read from MMC card in polling mode by using function HAL_MMC_ReadBlocks().
- This function support only 512-bytes block length (the block size should be
- chosen as 512 bytes).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to ensure that the transfer is done correctly. The check is done
- through HAL_MMC_GetCardState() function for MMC card state.
-
- (+) You can read from MMC card in DMA mode by using function HAL_MMC_ReadBlocks_DMA().
- This function support only 512-bytes block length (the block size should be
- chosen as 512 bytes).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to ensure that the transfer is done correctly. The check is done
- through HAL_MMC_GetCardState() function for MMC card state.
- You could also check the DMA transfer process through the MMC Rx interrupt event.
-
- (+) You can read from MMC card in Interrupt mode by using function HAL_MMC_ReadBlocks_IT().
- This function allows the read of 512 bytes blocks.
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to ensure that the transfer is done correctly. The check is done
- through HAL_MMC_GetCardState() function for MMC card state.
- You could also check the IT transfer process through the MMC Rx interrupt event.
-
- *** MMC Card Write operation ***
- ===============================
- [..]
- (+) You can write to MMC card in polling mode by using function HAL_MMC_WriteBlocks().
- This function support only 512-bytes block length (the block size should be
- chosen as 512 bytes).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to ensure that the transfer is done correctly. The check is done
- through HAL_MMC_GetCardState() function for MMC card state.
-
- (+) You can write to MMC card in DMA mode by using function HAL_MMC_WriteBlocks_DMA().
- This function support only 512-bytes block length (the block size should be
- chosen as 512 byte).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to ensure that the transfer is done correctly. The check is done

- After this, you have to ensure that the transfer is done correctly. The check is done
- through HAL_MMC_GetCardState() function for MMC card state.
- You could also check the IT transfer process through the MMC Tx interrupt event.
-
- *** MMC card information ***
- ===========================
- [..]
- (+) To get MMC card information, you can use the function HAL_MMC_GetCardInfo().
- It returns useful information about the MMC card such as block size, card type,
- block number ...
-
- *** MMC card CSD register ***
- ============================
- [..]
- (+) The HAL_MMC_GetCardCSD() API allows to get the parameters of the CSD register.
- Some of the CSD parameters are useful for card initialization and identification.
-
- *** MMC card CID register ***
- ============================
- [..]
- (+) The HAL_MMC_GetCardCID() API allows to get the parameters of the CID register.
- Some of the CID parameters are useful for card initialization and identification.
-
- *** MMC HAL driver macros list ***
- ==================================
- [..]
- Below the list of most used macros in MMC HAL driver.
-
- (+) __HAL_MMC_ENABLE : Enable the MMC device

- (+) __HAL_MMC_DMA_ENABLE: Enable the SDMMC DMA transfer
- (+) __HAL_MMC_DMA_DISABLE: Disable the SDMMC DMA transfer
- (+) __HAL_MMC_ENABLE_IT: Enable the MMC device interrupt
- (+) __HAL_MMC_DISABLE_IT: Disable the MMC device interrupt
- (+) __HAL_MMC_GET_FLAG:Check whether the specified MMC flag is set or not
- (+) __HAL_MMC_CLEAR_FLAG: Clear the MMC's pending flags
-
- [..]
- (@) You can refer to the MMC HAL driver header file for more useful macros
-
- *** Callback registration ***
- =============================================
- [..]
- The compilation define USE_HAL_MMC_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- Use Functions @ref HAL_MMC_RegisterCallback() to register a user callback,
- it allows to register following callbacks:
- (+) TxCpltCallback : callback when a transmission transfer is completed.
- (+) RxCpltCallback : callback when a reception transfer is completed.
- (+) ErrorCallback : callback when error occurs.
- (+) AbortCpltCallback : callback when abort is completed.
- (+) MspInitCallback : MMC MspInit.
- (+) MspDeInitCallback : MMC MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- Use function @ref HAL_MMC_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function. It allows to reset following callbacks:
- (+) TxCpltCallback : callback when a transmission transfer is completed.
- (+) RxCpltCallback : callback when a reception transfer is completed.
- (+) ErrorCallback : callback when error occurs.
- (+) AbortCpltCallback : callback when abort is completed.
- (+) MspInitCallback : MMC MspInit.
- (+) MspDeInitCallback : MMC MspDeInit.
- This function) takes as parameters the HAL peripheral handle and the Callback ID.
-
- By default, after the @ref HAL_MMC_Init and if the state is HAL_MMC_STATE_RESET
- all callbacks are reset to the corresponding legacy weak (surcharged) functions.
- Exception done for MspInit and MspDeInit callbacks that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_MMC_Init
- and @ref HAL_MMC_DeInit only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_MMC_Init and @ref HAL_MMC_DeInit
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
-
- Callbacks can be registered/unregistered in READY state only.
- Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
- in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
- during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_MMC_RegisterCallback before calling @ref HAL_MMC_DeInit
- or @ref HAL_MMC_Init function.
-
- When The compilation define USE_HAL_MMC_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.

- * @brief NAND HAL module driver.
- * This file provides a generic firmware to drive NAND memories mounted
- * as external device.
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- This driver is a generic layered driver which contains a set of APIs used to
- control NAND flash memories. It uses the FSMC layer functions to interface
- with NAND devices. This driver is used as follows:
-
- (+) NAND flash memory configuration sequence using the function HAL_NAND_Init()
- with control and timing parameters for both common and attribute spaces.
-
- (+) Read NAND flash memory maker and device IDs using the function
- HAL_NAND_Read_ID(). The read information is stored in the NAND_ID_TypeDef
- structure declared by the function caller.
-
- (+) Access NAND flash memory by read/write operations using the functions
- HAL_NAND_Read_Page_8b()/HAL_NAND_Read_SpareArea_8b(),
- HAL_NAND_Write_Page_8b()/HAL_NAND_Write_SpareArea_8b(),
- HAL_NAND_Read_Page_16b()/HAL_NAND_Read_SpareArea_16b(),
- HAL_NAND_Write_Page_16b()/HAL_NAND_Write_SpareArea_16b()
- to read/write page(s)/spare area(s). These functions use specific device
- information (Block, page size..) predefined by the user in the NAND_DeviceConfigTypeDef
- structure. The read/write address information is contained by the Nand_Address_Typedef
- structure passed as parameter.
-
- (+) Perform NAND flash Reset chip operation using the function HAL_NAND_Reset().
-
- (+) Perform NAND flash erase block operation using the function HAL_NAND_Erase_Block().
- The erase block address information is contained in the Nand_Address_Typedef
- structure passed as parameter.
-
- (+) Read the NAND flash status operation using the function HAL_NAND_Read_Status().
-
- (+) You can also control the NAND device by calling the control APIs HAL_NAND_ECC_Enable()/
- HAL_NAND_ECC_Disable() to respectively enable/disable the ECC code correction
- feature or the function HAL_NAND_GetECC() to get the ECC correction code.
-
- (+) You can monitor the NAND device HAL state by calling the function
- HAL_NAND_GetState()
-
- [..]
- (@) This driver is a set of generic APIs which handle standard NAND flash operations.
- If a NAND flash device contains different operations and/or implementations,
- it should be implemented separately.
-
- *** Callback registration ***
- =============================================
- [..]
- The compilation define USE_HAL_NAND_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- Use Functions @ref HAL_NAND_RegisterCallback() to register a user callback,
- it allows to register following callbacks:
- (+) MspInitCallback : NAND MspInit.
- (+) MspDeInitCallback : NAND MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- Use function @ref HAL_NAND_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function. It allows to reset following callbacks:
- (+) MspInitCallback : NAND MspInit.
- (+) MspDeInitCallback : NAND MspDeInit.
- This function) takes as parameters the HAL peripheral handle and the Callback ID.
-
- By default, after the @ref HAL_NAND_Init and if the state is HAL_NAND_STATE_RESET
- all callbacks are reset to the corresponding legacy weak (surcharged) functions.
- Exception done for MspInit and MspDeInit callbacks that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_NAND_Init
- and @ref HAL_NAND_DeInit only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_NAND_Init and @ref HAL_NAND_DeInit
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
-
- Callbacks can be registered/unregistered in READY state only.
- Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
- in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
- during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_NAND_RegisterCallback before calling @ref HAL_NAND_DeInit
- or @ref HAL_NAND_Init function.
-
- When The compilation define USE_HAL_NAND_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.

- * @brief NOR HAL module driver.
- * This file provides a generic firmware to drive NOR memories mounted
- * as external device.
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- This driver is a generic layered driver which contains a set of APIs used to
- control NOR flash memories. It uses the FSMC layer functions to interface
- with NOR devices. This driver is used as follows:
-
- (+) NOR flash memory configuration sequence using the function HAL_NOR_Init()
- with control and timing parameters for both normal and extended mode.
-
- (+) Read NOR flash memory manufacturer code and device IDs using the function
- HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef
- structure declared by the function caller.
-
- (+) Access NOR flash memory by read/write data unit operations using the functions
- HAL_NOR_Read(), HAL_NOR_Program().
-
- (+) Perform NOR flash erase block/chip operations using the functions
- HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip().
-
- (+) Read the NOR flash CFI (common flash interface) IDs using the function
- HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef
- structure declared by the function caller.
-
- (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/
- HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation
-
- (+) You can monitor the NOR device HAL state by calling the function
- HAL_NOR_GetState()
- [..]
- (@) This driver is a set of generic APIs which handle standard NOR flash operations.
- If a NOR flash device contains different operations and/or implementations,
- it should be implemented separately.
-
- *** NOR HAL driver macros list ***
- =============================================
- [..]
- Below the list of most used macros in NOR HAL driver.
-
- (+) NOR_WRITE : NOR memory write data to specified address
-
- *** Callback registration ***
- =============================================
- [..]
- The compilation define USE_HAL_NOR_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- Use Functions @ref HAL_NOR_RegisterCallback() to register a user callback,
- it allows to register following callbacks:
- (+) MspInitCallback : NOR MspInit.
- (+) MspDeInitCallback : NOR MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- Use function @ref HAL_NOR_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function. It allows to reset following callbacks:
- (+) MspInitCallback : NOR MspInit.
- (+) MspDeInitCallback : NOR MspDeInit.
- This function) takes as parameters the HAL peripheral handle and the Callback ID.
-
- By default, after the @ref HAL_NOR_Init and if the state is HAL_NOR_STATE_RESET
- all callbacks are reset to the corresponding legacy weak (surcharged) functions.
- Exception done for MspInit and MspDeInit callbacks that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_NOR_Init
- and @ref HAL_NOR_DeInit only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_NOR_Init and @ref HAL_NOR_DeInit
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
-
- Callbacks can be registered/unregistered in READY state only.
- Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
- in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
- during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_NOR_RegisterCallback before calling @ref HAL_NOR_DeInit
- or @ref HAL_NOR_Init function.
-
- When The compilation define USE_HAL_NOR_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.

- * @brief PCCARD HAL module driver.
- * This file provides a generic firmware to drive PCCARD memories mounted
- * as external device.
- *
- @verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- This driver is a generic layered driver which contains a set of APIs used to
- control PCCARD/compact flash memories. It uses the FSMC layer functions
- to interface with PCCARD devices. This driver is used for:
-
- (+) PCCARD/Compact Flash memory configuration sequence using the function
- HAL_PCCARD_Init()/HAL_CF_Init() with control and timing parameters for
- both common and attribute spaces.
-
- (+) Read PCCARD/Compact Flash memory maker and device IDs using the function
- HAL_PCCARD_Read_ID()/HAL_CF_Read_ID(). The read information is stored in
- the CompactFlash_ID structure declared by the function caller.
-
- (+) Access PCCARD/Compact Flash memory by read/write operations using the functions
- HAL_PCCARD_Read_Sector()/ HAL_PCCARD_Write_Sector() -
- HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector.
-
- (+) Perform PCCARD/Compact Flash Reset chip operation using the function
- HAL_PCCARD_Reset()/HAL_CF_Reset.
-
- (+) Perform PCCARD/Compact Flash erase sector operation using the function
- HAL_PCCARD_Erase_Sector()/HAL_CF_Erase_Sector.
-
- (+) Read the PCCARD/Compact Flash status operation using the function
- HAL_PCCARD_ReadStatus()/HAL_CF_ReadStatus().
-
- (+) You can monitor the PCCARD/Compact Flash device HAL state by calling
- the function HAL_PCCARD_GetState()/HAL_CF_GetState()
-
- [..]
- (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
- operations. If a PCCARD/Compact Flash device contains different operations
- and/or implementations, it should be implemented separately.
-
- *** Callback registration ***
- =============================================
- [..]
- The compilation define USE_HAL_PCCARD_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- Use Functions @ref HAL_PCCARD_RegisterCallback() to register a user callback,
- it allows to register following callbacks:
- (+) MspInitCallback : PCCARD MspInit.
- (+) MspDeInitCallback : PCCARD MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- Use function @ref HAL_PCCARD_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function. It allows to reset following callbacks:
- (+) MspInitCallback : PCCARD MspInit.
- (+) MspDeInitCallback : PCCARD MspDeInit.
- This function) takes as parameters the HAL peripheral handle and the Callback ID.
-
- By default, after the @ref HAL_PCCARD_Init and if the state is HAL_PCCARD_STATE_RESET
- all callbacks are reset to the corresponding legacy weak (surcharged) functions.
- Exception done for MspInit and MspDeInit callbacks that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_PCCARD_Init
- and @ref HAL_PCCARD_DeInit only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_PCCARD_Init and @ref HAL_PCCARD_DeInit
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
-
- Callbacks can be registered/unregistered in READY state only.
- Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
- in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
- during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_PCCARD_RegisterCallback before calling @ref HAL_PCCARD_DeInit
- or @ref HAL_PCCARD_Init function.
-
- When The compilation define USE_HAL_PCCARD_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.

- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The PCD HAL driver can be used as follows:
-
- (#) Declare a PCD_HandleTypeDef handle structure, for example:
- PCD_HandleTypeDef hpcd;
-
- (#) Fill parameters of Init structure in HCD handle
-
- (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)
-
- (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
- (##) Enable the PCD/USB Low Level interface clock using
- (+++) __HAL_RCC_USB_CLK_ENABLE(); For USB Device only FS peripheral
-
- (##) Initialize the related GPIO clocks
- (##) Configure PCD pin-out
- (##) Configure PCD NVIC interrupt
-
- (#)Associate the Upper USB device stack to the HAL PCD Driver:
- (##) hpcd.pData = pdev;
-
- (#)Enable PCD transmission and reception:
- (##) HAL_PCD_Start();
-

- ===============================================================================
- ##### Peripheral Control functions #####
- ===============================================================================
-
- *** PVD configuration ***
- =========================
- [..]
- (+) The PVD is used to monitor the VDD power supply by comparing it to a
- threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
-
- (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
- than the PVD threshold. This event is internally connected to the EXTI
- line16 and can generate an interrupt if enabled. This is done through
- __HAL_PVD_EXTI_ENABLE_IT() macro.
- (+) The PVD is stopped in Standby mode.
-
- *** WakeUp pin configuration ***
- ================================
- [..]
- (+) WakeUp pin is used to wake up the system from Standby mode. This pin is
- forced in input pull-down configuration and is active on rising edges.
- (+) There is one WakeUp pin:
- WakeUp Pin 1 on PA.00.
-
- [..]
-
- *** Low Power modes configuration ***
- =====================================
- [..]
- The device features 3 low-power modes:
- (+) Sleep mode: CPU clock off, all peripherals including Cortex-M3 core peripherals like
- NVIC, SysTick, etc. are kept running
- (+) Stop mode: All clocks are stopped
- (+) Standby mode: 1.8V domain powered off
-
-
- *** Sleep mode ***
- ==================
- [..]
- (+) Entry:
- The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFx)
- functions with
- (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
- (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
-
- (+) Exit:
- (++) WFI entry mode, Any peripheral interrupt acknowledged by the nested vectored interrupt
- controller (NVIC) can wake up the device from Sleep mode.
- (++) WFE entry mode, Any wakeup event can wake up the device from Sleep mode.
- (+++) Any peripheral interrupt w/o NVIC configuration & SEVONPEND bit set in the Cortex (HAL_PWR_EnableSEVOnPend)
- (+++) Any EXTI Line (Internal or External) configured in Event mode
-
- *** Stop mode ***
- =================
- [..]
- The Stop mode is based on the Cortex-M3 deepsleep mode combined with peripheral
- clock gating. The voltage regulator can be configured either in normal or low-power mode.
- In Stop mode, all clocks in the 1.8 V domain are stopped, the PLL, the HSI and the HSE RC
- oscillators are disabled. SRAM and register contents are preserved.
- In Stop mode, all I/O pins keep the same state as in Run mode.
-
- (+) Entry:
- The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_REGULATOR_VALUE, PWR_SLEEPENTRY_WFx )
- function with:
- (++) PWR_REGULATOR_VALUE= PWR_MAINREGULATOR_ON: Main regulator ON.
- (++) PWR_REGULATOR_VALUE= PWR_LOWPOWERREGULATOR_ON: Low Power regulator ON.
- (++) PWR_SLEEPENTRY_WFx= PWR_SLEEPENTRY_WFI: enter STOP mode with WFI instruction
- (++) PWR_SLEEPENTRY_WFx= PWR_SLEEPENTRY_WFE: enter STOP mode with WFE instruction
- (+) Exit:
- (++) WFI entry mode, Any EXTI Line (Internal or External) configured in Interrupt mode with NVIC configured
- (++) WFE entry mode, Any EXTI Line (Internal or External) configured in Event mode.
-
- *** Standby mode ***
- ====================
- [..]
- The Standby mode allows to achieve the lowest power consumption. It is based on the
- Cortex-M3 deepsleep mode, with the voltage regulator disabled. The 1.8 V domain is
- consequently powered off. The PLL, the HSI oscillator and the HSE oscillator are also
- switched off. SRAM and register contents are lost except for registers in the Backup domain
- and Standby circuitry
-
- (+) Entry:
- (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
- (+) Exit:
- (++) WKUP pin rising edge, RTC alarm event rising edge, external Reset in
- NRSTpin, IWDG Reset
-
- *** Auto-wakeup (AWU) from low-power mode ***
- =============================================
- [..]
-
- (+) The MCU can be woken up from low-power mode by an RTC Alarm event,
- without depending on an external interrupt (Auto-wakeup mode).
-
- (+) RTC auto-wakeup (AWU) from the Stop and Standby modes
-
- (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to
- configure the RTC to generate the RTC alarm using the HAL_RTC_SetAlarm_IT() function.
-
- *** PWR Workarounds linked to Silicon Limitation ***
- ====================================================
- [..]
- Below the list of all silicon limitations known on STM32F1xx prouct.

- (#)Workarounds Implemented inside PWR HAL Driver
- (##)Debugging Stop mode with WFE entry - overloaded the WFE by an internal function

- * @brief RCC HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Reset and Clock Control (RCC) peripheral:
- * + Initialization and de-initialization functions
- * + Peripheral Control functions
- *
- @verbatim
- ==============================================================================
- ##### RCC specific features #####
- ==============================================================================
- [..]
- After reset the device is running from Internal High Speed oscillator
- (HSI 8MHz) with Flash 0 wait state, Flash prefetch buffer is enabled,
- and all peripherals are off except internal SRAM, Flash and JTAG.
- (+) There is no prescaler on High speed (AHB) and Low speed (APB) buses;
- all peripherals mapped on these buses are running at HSI speed.
- (+) The clock for all peripherals is switched off, except the SRAM and FLASH.
- (+) All GPIOs are in input floating state, except the JTAG pins which
- are assigned to be used for debug purpose.
- [..] Once the device started from reset, the user application has to:
- (+) Configure the clock source to be used to drive the System clock
- (if the application needs higher frequency/performance)
- (+) Configure the System clock frequency and Flash settings
- (+) Configure the AHB and APB buses prescalers
- (+) Enable the clock for the peripheral(s) to be used
- (+) Configure the clock source(s) for peripherals whose clocks are not
- derived from the System clock (I2S, RTC, ADC, USB OTG FS)
-
- ##### RCC Limitations #####
- ==============================================================================
- [..]
- A delay between an RCC peripheral clock enable and the effective peripheral
- enabling should be taken into account in order to manage the peripheral read/write
- from/to registers.
- (+) This delay depends on the peripheral mapping.
- (++) AHB & APB peripherals, 1 dummy read is necessary
-
- [..]
- Workarounds:
- (#) For AHB & APB peripherals, a dummy read to the peripheral register has been
- inserted in each __HAL_RCC_PPP_CLK_ENABLE() macro.

- [..]
- This section provides functions allowing to configure the internal/external oscillators
- (HSE, HSI, LSE, LSI, PLL, CSS and MCO) and the System buses clocks (SYSCLK, AHB, APB1
- and APB2).
-
- [..] Internal/external clock and PLL configuration
- (#) HSI (high-speed internal), 8 MHz factory-trimmed RC used directly or through
- the PLL as System clock source.
- (#) LSI (low-speed internal), ~40 KHz low consumption RC used as IWDG and/or RTC
- clock source.
-
- (#) HSE (high-speed external), 4 to 24 MHz (STM32F100xx) or 4 to 16 MHz (STM32F101x/STM32F102x/STM32F103x) or 3 to 25 MHz (STM32F105x/STM32F107x) crystal oscillator used directly or
- through the PLL as System clock source. Can be used also as RTC clock source.
-
- (#) LSE (low-speed external), 32 KHz oscillator used as RTC clock source.
-
- (#) PLL (clocked by HSI or HSE), featuring different output clocks:
- (++) The first output is used to generate the high speed system clock (up to 72 MHz for STM32F10xxx or up to 24 MHz for STM32F100xx)
- (++) The second output is used to generate the clock for the USB OTG FS (48 MHz)
-
- (#) CSS (Clock security system), once enable using the macro __HAL_RCC_CSS_ENABLE()
- and if a HSE clock failure occurs(HSE used directly or through PLL as System
- clock source), the System clocks automatically switched to HSI and an interrupt
- is generated if enabled. The interrupt is linked to the Cortex-M3 NMI
- (Non-Maskable Interrupt) exception vector.
-
- (#) MCO1 (microcontroller clock output), used to output SYSCLK, HSI,
- HSE or PLL clock (divided by 2) on PA8 pin + PLL2CLK, PLL3CLK/2, PLL3CLK and XTI for STM32F105x/STM32F107x
-
- [..] System, AHB and APB buses clocks configuration
- (#) Several clock sources can be used to drive the System clock (SYSCLK): HSI,
- HSE and PLL.
- The AHB clock (HCLK) is derived from System clock through configurable
- prescaler and used to clock the CPU, memory and peripherals mapped
- on AHB bus (DMA, GPIO...). APB1 (PCLK1) and APB2 (PCLK2) clocks are derived
- from AHB clock through configurable prescalers and used to clock
- the peripherals mapped on these buses. You can use
- "@ref HAL_RCC_GetSysClockFreq()" function to retrieve the frequencies of these clocks.
-
- -@- All the peripheral clocks are derived from the System clock (SYSCLK) except:
- (+@) RTC: RTC clock can be derived either from the LSI, LSE or HSE clock
- divided by 128.
- (+@) USB OTG FS and RTC: USB OTG FS require a frequency equal to 48 MHz
- to work correctly. This clock is derived of the main PLL through PLL Multiplier.
- (+@) I2S interface on STM32F105x/STM32F107x can be derived from PLL3CLK
- (+@) IWDG clock which is always the LSI clock.
-
- (#) For STM32F10xxx, the maximum frequency of the SYSCLK and HCLK/PCLK2 is 72 MHz, PCLK1 36 MHz.
- For STM32F100xx, the maximum frequency of the SYSCLK and HCLK/PCLK1/PCLK2 is 24 MHz.
- Depending on the SYSCLK frequency, the flash latency should be adapted accordingly.

- * @brief RTC HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Real Time Clock (RTC) peripheral:
- * + Initialization and de-initialization functions
- * + RTC Time and Date functions
- * + RTC Alarm functions
- * + Peripheral Control functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==================================================================
- [..]
- (+) Enable the RTC domain access (see description in the section above).
- (+) Configure the RTC Prescaler (Asynchronous prescaler to generate RTC 1Hz time base)
- using the HAL_RTC_Init() function.
-
- *** Time and Date configuration ***
- ===================================
- [..]
- (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime()
- and HAL_RTC_SetDate() functions.
- (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions.
-
- *** Alarm configuration ***
- ===========================
- [..]
- (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function.
- You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
- (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
-
- *** Tamper configuration ***
- ============================
- [..]
- (+) Enable the RTC Tamper and configure the Tamper Level using the
- HAL_RTCEx_SetTamper() function. You can configure RTC Tamper with interrupt
- mode using HAL_RTCEx_SetTamper_IT() function.
- (+) The TAMPER1 alternate function can be mapped to PC13
-
- *** Backup Data Registers configuration ***
- ===========================================
- [..]
- (+) To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite()
- function.
- (+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead()
- function.
-
- ##### WARNING: Drivers Restrictions #####
- ==================================================================
- [..] RTC version used on STM32F1 families is version V1. All the features supported by V2
- (other families) will be not supported on F1.
- [..] As on V2, main RTC features are managed by HW. But on F1, date feature is completely
- managed by SW.
- [..] Then, there are some restrictions compared to other families:
- (+) Only format 24 hours supported in HAL (format 12 hours not supported)
- (+) Date is saved in SRAM. Then, when MCU is in STOP or STANDBY mode, date will be lost.
- User should implement a way to save date before entering in low power mode (an
- example is provided with firmware package based on backup registers)
- (+) Date is automatically updated each time a HAL_RTC_GetTime or HAL_RTC_GetDate is called.
- (+) Alarm detection is limited to 1 day. It will expire only 1 time (no alarm repetition, need
- to program a new alarm)
-
- ##### Backup Domain Operating Condition #####
- ==============================================================================
- [..] The real-time clock (RTC) and the RTC backup registers can be powered
- from the VBAT voltage when the main VDD supply is powered off.
- To retain the content of the RTC backup registers and supply the RTC
- when VDD is turned off, VBAT pin can be connected to an optional
- standby voltage supplied by a battery or by another source.
-
- [..] To allow the RTC operating even when the main digital supply (VDD) is turned
- off, the VBAT pin powers the following blocks:
- (#) The RTC
- (#) The LSE oscillator
- (#) The backup SRAM when the low power backup regulator is enabled
- (#) PC13 to PC15 I/Os, plus PI8 I/O (when available)
-
- [..] When the backup domain is supplied by VDD (analog switch connected to VDD),
- the following pins are available:
- (+) PC13 can be used as a Tamper pin
-
- [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT
- because VDD is not present), the following pins are available:
- (+) PC13 can be used as the Tamper pin
-
- ##### Backup Domain Reset #####
- ==================================================================
- [..] The backup domain reset sets all RTC registers and the RCC_BDCR register
- to their reset values.
- [..] A backup domain reset is generated when one of the following events occurs:
- (#) Software reset, triggered by setting the BDRST bit in the
- RCC Backup domain control register (RCC_BDCR).
- (#) VDD or VBAT power on, if both supplies have previously been powered off.
- (#) Tamper detection event resets all data backup registers.
-
- ##### Backup Domain Access #####
- ==================================================================
- [..] After reset, the backup domain (RTC registers, RTC backup data
- registers and backup SRAM) is protected against possible unwanted write
- accesses.
- [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
- (+) Call the function HAL_RCCEx_PeriphCLKConfig in using RCC_PERIPHCLK_RTC for
- PeriphClockSelection and select RTCClockSelection (LSE, LSI or HSE)
- (+) Enable the BKP clock in using __HAL_RCC_BKP_CLK_ENABLE()
-
- ##### RTC and low power modes #####
- ==================================================================
- [..] The MCU can be woken up from a low power mode by an RTC alternate
- function.
- [..] The RTC alternate functions are the RTC alarms (Alarm A),
- and RTC tamper event detection.
- These RTC alternate functions can wake up the system from the Stop and
- Standby low power modes.
- [..] The system can also wake up from low power modes without depending
- on an external interrupt (Auto-wakeup mode), by using the RTC alarm.
-
- *** Callback registration ***
- =============================================
- [..]
- The compilation define USE_HAL_RTC_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
- Use Function @ref HAL_RTC_RegisterCallback() to register an interrupt callback.
-
- [..]
- Function @ref HAL_RTC_RegisterCallback() allows to register following callbacks:
- (+) AlarmAEventCallback : RTC Alarm A Event callback.
- (+) Tamper1EventCallback : RTC Tamper 1 Event callback.
- (+) MspInitCallback : RTC MspInit callback.
- (+) MspDeInitCallback : RTC MspDeInit callback.
- [..]
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- [..]
- Use function @ref HAL_RTC_UnRegisterCallback() to reset a callback to the default
- weak function.
- @ref HAL_RTC_UnRegisterCallback() takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) AlarmAEventCallback : RTC Alarm A Event callback.
- (+) Tamper1EventCallback : RTC Tamper 1 Event callback.
- (+) MspInitCallback : RTC MspInit callback.
- (+) MspDeInitCallback : RTC MspDeInit callback.
- [..]
- By default, after the @ref HAL_RTC_Init() and when the state is HAL_RTC_STATE_RESET,
- all callbacks are set to the corresponding weak functions :
- example @ref AlarmAEventCallback().
- Exception done for MspInit and MspDeInit callbacks that are reset to the legacy weak function
- in the @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit() only when these callbacks are null
- (not registered beforehand).
- If not, MspInit or MspDeInit are not null, @ref HAL_RTC_Init()/@ref HAL_RTC_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
- [..]
- Callbacks can be registered/unregistered in HAL_RTC_STATE_READY state only.
- Exception done MspInit/MspDeInit that can be registered/unregistered
- in HAL_RTC_STATE_READY or HAL_RTC_STATE_RESET state,
- thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_RTC_RegisterCallback() before calling @ref HAL_RTC_DeInit()
- or @ref HAL_RTC_Init() function.
- [..]
- When The compilation define USE_HAL_RTC_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available and all callbacks
- are set to the corresponding weak functions.

- ===============================================================================
- [..] This section provides functions allowing to initialize and configure the
- RTC Prescaler (Asynchronous), disable RTC registers Write protection,
- enter and exit the RTC initialization mode,
- RTC registers synchronization check and reference clock detection enable.
- (#) The RTC Prescaler should be programmed to generate the RTC 1Hz time base.
- (#) All RTC registers are Write protected. Writing to the RTC registers
- is enabled by setting the CNF bit in the RTC_CRL register.
- (#) To read the calendar after wakeup from low power modes (Standby or Stop)
- the software must first wait for the RSF bit (Register Synchronized Flag)
- in the RTC_CRL register to be set by hardware.
- The HAL_RTC_WaitForSynchro() function implements the above software
- sequence (RSF clear and RSF check).

- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- This driver implements a high level communication layer for read and write from/to
- this memory. The needed STM32 hardware resources (SDIO and GPIO) are performed by
- the user in HAL_SD_MspInit() function (MSP layer).
- Basically, the MSP layer configuration should be the same as we provide in the
- examples.
- You can easily tailor this configuration according to hardware resources.
-
- [..]
- This driver is a generic layered driver for SDIO memories which uses the HAL
- SDIO driver functions to interface with SD and uSD cards devices.
- It is used as follows:
-
- (#)Initialize the SDIO low level resources by implementing the HAL_SD_MspInit() API:
- (##) Enable the SDIO interface clock using __HAL_RCC_SDIO_CLK_ENABLE();
- (##) SDIO pins configuration for SD card
- (+++) Enable the clock for the SDIO GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
- (+++) Configure these SDIO pins as alternate function pull-up using HAL_GPIO_Init()
- and according to your pin assignment;
- (##) DMA configuration if you need to use DMA process (HAL_SD_ReadBlocks_DMA()
- and HAL_SD_WriteBlocks_DMA() APIs).
- (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE();
- (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled.
- (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
- (+++) Configure the SDIO and DMA interrupt priorities using functions
- HAL_NVIC_SetPriority(); DMA priority is superior to SDIO's priority
- (+++) Enable the NVIC DMA and SDIO IRQs using function HAL_NVIC_EnableIRQ()
- (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT()
- and __HAL_SD_DISABLE_IT() inside the communication process.
- (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
- and __HAL_SD_CLEAR_IT()
- (##) NVIC configuration if you need to use interrupt process (HAL_SD_ReadBlocks_IT()
- and HAL_SD_WriteBlocks_IT() APIs).
- (+++) Configure the SDIO interrupt priorities using function HAL_NVIC_SetPriority();
- (+++) Enable the NVIC SDIO IRQs using function HAL_NVIC_EnableIRQ()
- (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT()
- and __HAL_SD_DISABLE_IT() inside the communication process.
- (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
- and __HAL_SD_CLEAR_IT()
- (#) At this stage, you can perform SD read/write/erase operations after SD card initialization
-
-
- *** SD Card Initialization and configuration ***
- ================================================
- [..]
- To initialize the SD Card, use the HAL_SD_Init() function. It Initializes
- SDIO Peripheral(STM32 side) and the SD Card, and put it into StandBy State (Ready for data transfer).
- This function provide the following operations:
-
- (#) Apply the SD Card initialization process at 400KHz and check the SD Card
- type (Standard Capacity or High Capacity). You can change or adapt this
- frequency by adjusting the "ClockDiv" field.
- The SD Card frequency (SDIO_CK) is computed as follows:
-
- SDIO_CK = SDIOCLK / (ClockDiv + 2)
-
- In initialization mode and according to the SD Card standard,
- make sure that the SDIO_CK frequency doesn't exceed 400KHz.
-
- This phase of initialization is done through SDIO_Init() and
- SDIO_PowerState_ON() SDIO low level APIs.
-
- (#) Initialize the SD card. The API used is HAL_SD_InitCard().
- This phase allows the card initialization and identification
- and check the SD Card type (Standard Capacity or High Capacity)
- The initialization flow is compatible with SD standard.
-
- This API (HAL_SD_InitCard()) could be used also to reinitialize the card in case
- of plug-off plug-in.
-
- (#) Configure the SD Card Data transfer frequency. You can change or adapt this
- frequency by adjusting the "ClockDiv" field.
- In transfer mode and according to the SD Card standard, make sure that the
- SDIO_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
- To be able to use a frequency higher than 24MHz, you should use the SDIO
- peripheral in bypass mode. Refer to the corresponding reference manual
- for more details.
-
- (#) Select the corresponding SD Card according to the address read with the step 2.
-
- (#) Configure the SD Card in wide bus mode: 4-bits data.
-
- *** SD Card Read operation ***
- ==============================
- [..]
- (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks().
- This function support only 512-bytes block length (the block size should be
- chosen as 512 bytes).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to ensure that the transfer is done correctly. The check is done
- through HAL_SD_GetCardState() function for SD card state.
-
- (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
- This function support only 512-bytes block length (the block size should be
- chosen as 512 bytes).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to ensure that the transfer is done correctly. The check is done
- through HAL_SD_GetCardState() function for SD card state.
- You could also check the DMA transfer process through the SD Rx interrupt event.
-
- (+) You can read from SD card in Interrupt mode by using function HAL_SD_ReadBlocks_IT().
- This function support only 512-bytes block length (the block size should be
- chosen as 512 bytes).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to ensure that the transfer is done correctly. The check is done
- through HAL_SD_GetCardState() function for SD card state.
- You could also check the IT transfer process through the SD Rx interrupt event.
-
- *** SD Card Write operation ***
- ===============================
- [..]
- (+) You can write to SD card in polling mode by using function HAL_SD_WriteBlocks().
- This function support only 512-bytes block length (the block size should be
- chosen as 512 bytes).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to ensure that the transfer is done correctly. The check is done
- through HAL_SD_GetCardState() function for SD card state.
-
- (+) You can write to SD card in DMA mode by using function HAL_SD_WriteBlocks_DMA().
- This function support only 512-bytes block length (the block size should be
- chosen as 512 bytes).
- You can choose either one block read operation or multiple block read operation
- by adjusting the "NumberOfBlocks" parameter.
- After this, you have to ensure that the transfer is done correctly. The check is done
- through HAL_SD_GetCardState() function for SD card state.
- You could also check the DMA transfer process through the SD Tx interrupt event.
-
- (+) You can write to SD card in Interrupt mode by using function HAL_SD_WriteBlocks_IT().
- This function support only 512-bytes block length (the block size should be
- chosen as 512 bytes).
- You can choose either one block read operation or multiple block read operation

- through HAL_SD_GetCardState() function for SD card state.
- You could also check the IT transfer process through the SD Tx interrupt event.
-
- *** SD card status ***
- ======================
- [..]
- (+) The SD Status contains status bits that are related to the SD Memory
- Card proprietary features. To get SD card status use the HAL_SD_GetCardStatus().
-
- *** SD card information ***
- ===========================
- [..]
- (+) To get SD card information, you can use the function HAL_SD_GetCardInfo().
- It returns useful information about the SD card such as block size, card type,
- block number ...
-
- *** SD card CSD register ***
- ============================
- (+) The HAL_SD_GetCardCSD() API allows to get the parameters of the CSD register.
- Some of the CSD parameters are useful for card initialization and identification.
-
- *** SD card CID register ***
- ============================
- (+) The HAL_SD_GetCardCID() API allows to get the parameters of the CID register.
- Some of the CSD parameters are useful for card initialization and identification.
-
- *** SD HAL driver macros list ***
- ==================================
- [..]
- Below the list of most used macros in SD HAL driver.
-
- (+) __HAL_SD_ENABLE : Enable the SD device
- (+) __HAL_SD_DISABLE : Disable the SD device
- (+) __HAL_SD_DMA_ENABLE: Enable the SDIO DMA transfer
- (+) __HAL_SD_DMA_DISABLE: Disable the SDIO DMA transfer
- (+) __HAL_SD_ENABLE_IT: Enable the SD device interrupt
- (+) __HAL_SD_DISABLE_IT: Disable the SD device interrupt
- (+) __HAL_SD_GET_FLAG:Check whether the specified SD flag is set or not
- (+) __HAL_SD_CLEAR_FLAG: Clear the SD's pending flags
-
- (@) You can refer to the SD HAL driver header file for more useful macros
-
- *** Callback registration ***
- =============================================
- [..]
- The compilation define USE_HAL_SD_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- Use Functions @ref HAL_SD_RegisterCallback() to register a user callback,
- it allows to register following callbacks:
- (+) TxCpltCallback : callback when a transmission transfer is completed.
- (+) RxCpltCallback : callback when a reception transfer is completed.
- (+) ErrorCallback : callback when error occurs.
- (+) AbortCpltCallback : callback when abort is completed.
- (+) MspInitCallback : SD MspInit.
- (+) MspDeInitCallback : SD MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- Use function @ref HAL_SD_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function. It allows to reset following callbacks:
- (+) TxCpltCallback : callback when a transmission transfer is completed.
- (+) RxCpltCallback : callback when a reception transfer is completed.
- (+) ErrorCallback : callback when error occurs.
- (+) AbortCpltCallback : callback when abort is completed.
- (+) MspInitCallback : SD MspInit.
- (+) MspDeInitCallback : SD MspDeInit.
- This function) takes as parameters the HAL peripheral handle and the Callback ID.
-
- By default, after the @ref HAL_SD_Init and if the state is HAL_SD_STATE_RESET
- all callbacks are reset to the corresponding legacy weak (surcharged) functions.
- Exception done for MspInit and MspDeInit callbacks that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_SD_Init
- and @ref HAL_SD_DeInit only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_SD_Init and @ref HAL_SD_DeInit
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
-
- Callbacks can be registered/unregistered in READY state only.
- Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
- in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
- during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_SD_RegisterCallback before calling @ref HAL_SD_DeInit
- or @ref HAL_SD_Init function.
-
- When The compilation define USE_HAL_SD_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.

- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The SMARTCARD HAL driver can be used as follows:
-
- (#) Declare a SMARTCARD_HandleTypeDef handle structure.
- (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
- (##) Enable the interface clock of the USARTx associated to the SMARTCARD.
- (##) SMARTCARD pins configuration:
- (+++) Enable the clock for the SMARTCARD GPIOs.
- (+++) Configure SMARTCARD pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
- and HAL_SMARTCARD_Receive_IT() APIs):
- (+++) Configure the USARTx interrupt priority.
- (+++) Enable the NVIC USART IRQ handle.
- (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
- and HAL_SMARTCARD_Receive_DMA() APIs):
- (+++) Declare a DMA handle structure for the Tx/Rx channel.
- (+++) Enable the DMAx interface clock.
- (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+++) Configure the DMA Tx/Rx channel.
- (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
- (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
- (used for last byte sending completion detection in DMA non circular mode)
-
- (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware
- flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure.
-
- (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
- (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customized HAL_SMARTCARD_MspInit() API.
- [..]
- (@) The specific SMARTCARD interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
-
- [..]
- Three operation modes are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Send an amount of data in blocking mode using HAL_SMARTCARD_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_SMARTCARD_Receive()
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Send an amount of data in non blocking mode using HAL_SMARTCARD_Transmit_IT()
- (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
- (+) Receive an amount of data in non blocking mode using HAL_SMARTCARD_Receive_IT()
- (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback
- (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback
-
- *** DMA mode IO operation ***
- ==============================
- [..]
- (+) Send an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Transmit_DMA()
- (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
- (+) Receive an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Receive_DMA()
- (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback
- (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback
-
- *** SMARTCARD HAL driver macros list ***
- ========================================
- [..]
- Below the list of most used macros in SMARTCARD HAL driver.
-
- (+) __HAL_SMARTCARD_ENABLE: Enable the SMARTCARD peripheral
- (+) __HAL_SMARTCARD_DISABLE: Disable the SMARTCARD peripheral
- (+) __HAL_SMARTCARD_GET_FLAG : Check whether the specified SMARTCARD flag is set or not
- (+) __HAL_SMARTCARD_CLEAR_FLAG : Clear the specified SMARTCARD pending flag
- (+) __HAL_SMARTCARD_ENABLE_IT: Enable the specified SMARTCARD interrupt
- (+) __HAL_SMARTCARD_DISABLE_IT: Disable the specified SMARTCARD interrupt
-
- [..]
- (@) You can refer to the SMARTCARD HAL driver header file for more useful macros
-
- ##### Callback registration #####
- ==================================
-
- [..]
- The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- [..]
- Use Function @ref HAL_SMARTCARD_RegisterCallback() to register a user callback.
- Function @ref HAL_SMARTCARD_RegisterCallback() allows to register following callbacks:
- (+) TxCpltCallback : Tx Complete Callback.
- (+) RxCpltCallback : Rx Complete Callback.
- (+) ErrorCallback : Error Callback.
- (+) AbortCpltCallback : Abort Complete Callback.
- (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
- (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
- (+) MspInitCallback : SMARTCARD MspInit.
- (+) MspDeInitCallback : SMARTCARD MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- [..]
- Use function @ref HAL_SMARTCARD_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function.
- @ref HAL_SMARTCARD_UnRegisterCallback() takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) TxCpltCallback : Tx Complete Callback.
- (+) RxCpltCallback : Rx Complete Callback.
- (+) ErrorCallback : Error Callback.
- (+) AbortCpltCallback : Abort Complete Callback.
- (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
- (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
- (+) MspInitCallback : SMARTCARD MspInit.
- (+) MspDeInitCallback : SMARTCARD MspDeInit.
-
- [..]
- By default, after the @ref HAL_SMARTCARD_Init() and when the state is HAL_SMARTCARD_STATE_RESET
- all callbacks are set to the corresponding weak (surcharged) functions:
- examples @ref HAL_SMARTCARD_TxCpltCallback(), @ref HAL_SMARTCARD_RxCpltCallback().
- Exception done for MspInit and MspDeInit functions that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_SMARTCARD_Init()
- and @ref HAL_SMARTCARD_DeInit() only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_SMARTCARD_Init() and @ref HAL_SMARTCARD_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
-
- [..]
- Callbacks can be registered/unregistered in HAL_SMARTCARD_STATE_READY state only.
- Exception done MspInit/MspDeInit that can be registered/unregistered
- in HAL_SMARTCARD_STATE_READY or HAL_SMARTCARD_STATE_RESET state, thus registered (user)
- MspInit/DeInit callbacks can be used during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_SMARTCARD_RegisterCallback() before calling @ref HAL_SMARTCARD_DeInit()
- or @ref HAL_SMARTCARD_Init() function.
-
- [..]
- When The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available
- and weak (surcharged) callbacks are used.

- ==============================================================================
- ##### Initialization and Configuration functions #####
- ==============================================================================
- [..]
- This subsection provides a set of functions allowing to initialize the USART
- in Smartcard mode.
- [..]
- The Smartcard interface is designed to support asynchronous protocol Smartcards as
- defined in the ISO 7816-3 standard.
- [..]
- The USART can provide a clock to the smartcard through the SCLK output.
- In smartcard mode, SCLK is not associated to the communication but is simply derived
- from the internal peripheral input clock through a 5-bit prescaler.
- [..]
- (+) For the Smartcard mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length => Should be 9 bits (8 bits + parity)
- (++) Stop Bit
- (++) Parity: => Should be enabled
- (++) USART polarity
- (++) USART phase
- (++) USART LastBit
- (++) Receiver/transmitter modes
- (++) Prescaler
- (++) GuardTime
- (++) NACKState: The Smartcard NACK state
-
- (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card:
- (++) Word Length = 9 Bits
- (++) 1.5 Stop Bit
- (++) Even parity
- (++) BaudRate = 12096 baud
- (++) Tx and Rx enabled
- [..]
- Please refer to the ISO 7816-3 specification for more details.
-
- [..]
- (@) It is also possible to choose 0.5 stop bit for receiving but it is recommended
- to use 1.5 stop bits for both transmitting and receiving to avoid switching
- between the two configurations.
- [..]
- The HAL_SMARTCARD_Init() function follows the USART SmartCard configuration
- procedures (details for the procedures are available in reference manuals
- (RM0008 for STM32F10Xxx MCUs and RM0041 for STM32F100xx MCUs)).
-
-@endverbatim
-
- The SMARTCARD frame format is given in the following table:
- +-------------------------------------------------------------+
- | M bit | PCE bit | SMARTCARD frame |
- |---------------------|---------------------------------------|
- | 1 | 1 | | SB | 8 bit data | PB | STB | |

-@verbatim
- ===============================================================================
- ##### IO operation functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
-
- [..]
- (#) Smartcard is a single wire half duplex communication protocol.
- The Smartcard interface is designed to support asynchronous protocol Smartcards as
- defined in the ISO 7816-3 standard.
- (#) The USART should be configured as:
- (++) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
- (++) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.
-
- (#) There are two modes of transfer:
- (++) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (++) Non Blocking mode: The communication is performed using Interrupts
- or DMA, These APIs return the HAL status.
- The end of the data processing will be indicated through the
- dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
- will be executed respectively at the end of the Transmit or Receive process
- The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication error is detected
-
- (#) Blocking mode APIs are :
- (++) HAL_SMARTCARD_Transmit()
- (++) HAL_SMARTCARD_Receive()
-
- (#) Non Blocking mode APIs with Interrupt are :
- (++) HAL_SMARTCARD_Transmit_IT()
- (++) HAL_SMARTCARD_Receive_IT()
- (++) HAL_SMARTCARD_IRQHandler()
-
- (#) Non Blocking mode functions with DMA are :
- (++) HAL_SMARTCARD_Transmit_DMA()
- (++) HAL_SMARTCARD_Receive_DMA()
-
- (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
- (++) HAL_SMARTCARD_TxCpltCallback()
- (++) HAL_SMARTCARD_RxCpltCallback()
- (++) HAL_SMARTCARD_ErrorCallback()
-
- (#) Non-Blocking mode transfers could be aborted using Abort API's :
- (+) HAL_SMARTCARD_Abort()
- (+) HAL_SMARTCARD_AbortTransmit()
- (+) HAL_SMARTCARD_AbortReceive()
- (+) HAL_SMARTCARD_Abort_IT()
- (+) HAL_SMARTCARD_AbortTransmit_IT()
- (+) HAL_SMARTCARD_AbortReceive_IT()
-
- (#) For Abort services based on interrupts (HAL_SMARTCARD_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
- (+) HAL_SMARTCARD_AbortCpltCallback()
- (+) HAL_SMARTCARD_AbortTransmitCpltCallback()
- (+) HAL_SMARTCARD_AbortReceiveCpltCallback()
-
- (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
- Errors are handled as follows :
- (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
- to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
- Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
- and HAL_SMARTCARD_ErrorCallback() user callback is executed. Transfer is kept ongoing on SMARTCARD side.
- If user wants to abort it, Abort services should be called by user.
- (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
- This concerns Frame Error in Interrupt mode tranmission, Overrun Error in Interrupt mode reception and all errors in DMA mode.
- Error code is set to allow user to identify error type, and HAL_SMARTCARD_ErrorCallback() user callback is executed.

- * @brief SPI HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Serial Peripheral Interface (SPI) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral Control functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The SPI HAL driver can be used as follows:
-
- (#) Declare a SPI_HandleTypeDef handle structure, for example:
- SPI_HandleTypeDef hspi;
-
- (#)Initialize the SPI low level resources by implementing the HAL_SPI_MspInit() API:
- (##) Enable the SPIx interface clock
- (##) SPI pins configuration
- (+++) Enable the clock for the SPI GPIOs
- (+++) Configure these SPI pins as alternate function push-pull
- (##) NVIC configuration if you need to use interrupt process
- (+++) Configure the SPIx interrupt priority
- (+++) Enable the NVIC SPI IRQ handle
- (##) DMA Configuration if you need to use DMA process
- (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive Stream/Channel
- (+++) Enable the DMAx clock
- (+++) Configure the DMA handle parameters
- (+++) Configure the DMA Tx or Rx Stream/Channel
- (+++) Associate the initialized hdma_tx(or _rx) handle to the hspi DMA Tx or Rx handle
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream/Channel
-
- (#) Program the Mode, BidirectionalMode , Data size, Baudrate Prescaler, NSS
- management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure.
-
- (#) Initialize the SPI registers by calling the HAL_SPI_Init() API:
- (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customized HAL_SPI_MspInit() API.
- [..]
- Circular mode restriction:
- (#) The DMA circular mode cannot be used when the SPI is configured in these modes:
- (##) Master 2Lines RxOnly
- (##) Master 1Line Rx
- (#) The CRC feature is not managed when the DMA circular mode is enabled
- (#) When the SPI DMA Pause/Stop features are used, we must use the following APIs
- the HAL_SPI_DMAPause()/ HAL_SPI_DMAStop() only under the SPI callbacks
- [..]
- Master Receive mode restriction:
- (#) In Master unidirectional receive-only mode (MSTR =1, BIDIMODE=0, RXONLY=1) or
- bidirectional receive mode (MSTR=1, BIDIMODE=1, BIDIOE=0), to ensure that the SPI
- does not initiate a new transfer the following procedure has to be respected:
- (##) HAL_SPI_DeInit()
- (##) HAL_SPI_Init()
- [..]
- Callback registration:
-
- (#) The compilation flag USE_HAL_SPI_REGISTER_CALLBACKS when set to 1U
- allows the user to configure dynamically the driver callbacks.
- Use Functions HAL_SPI_RegisterCallback() to register an interrupt callback.
-
- Function HAL_SPI_RegisterCallback() allows to register following callbacks:
- (++) TxCpltCallback : SPI Tx Completed callback
- (++) RxCpltCallback : SPI Rx Completed callback
- (++) TxRxCpltCallback : SPI TxRx Completed callback
- (++) TxHalfCpltCallback : SPI Tx Half Completed callback
- (++) RxHalfCpltCallback : SPI Rx Half Completed callback
- (++) TxRxHalfCpltCallback : SPI TxRx Half Completed callback
- (++) ErrorCallback : SPI Error callback
- (++) AbortCpltCallback : SPI Abort callback
- (++) MspInitCallback : SPI Msp Init callback
- (++) MspDeInitCallback : SPI Msp DeInit callback
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
-
- (#) Use function HAL_SPI_UnRegisterCallback to reset a callback to the default
- weak function.
- HAL_SPI_UnRegisterCallback takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (++) TxCpltCallback : SPI Tx Completed callback
- (++) RxCpltCallback : SPI Rx Completed callback
- (++) TxRxCpltCallback : SPI TxRx Completed callback
- (++) TxHalfCpltCallback : SPI Tx Half Completed callback
- (++) RxHalfCpltCallback : SPI Rx Half Completed callback
- (++) TxRxHalfCpltCallback : SPI TxRx Half Completed callback
- (++) ErrorCallback : SPI Error callback
- (++) AbortCpltCallback : SPI Abort callback
- (++) MspInitCallback : SPI Msp Init callback
- (++) MspDeInitCallback : SPI Msp DeInit callback
-
- [..]
- By default, after the HAL_SPI_Init() and when the state is HAL_SPI_STATE_RESET
- all callbacks are set to the corresponding weak functions:
- examples HAL_SPI_MasterTxCpltCallback(), HAL_SPI_MasterRxCpltCallback().
- Exception done for MspInit and MspDeInit functions that are
- reset to the legacy weak functions in the HAL_SPI_Init()/ HAL_SPI_DeInit() only when
- these callbacks are null (not registered beforehand).
- If MspInit or MspDeInit are not null, the HAL_SPI_Init()/ HAL_SPI_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
-
- [..]
- Callbacks can be registered/unregistered in HAL_SPI_STATE_READY state only.
- Exception done MspInit/MspDeInit functions that can be registered/unregistered
- in HAL_SPI_STATE_READY or HAL_SPI_STATE_RESET state,
- thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
- Then, the user first registers the MspInit/MspDeInit user callbacks
- using HAL_SPI_RegisterCallback() before calling HAL_SPI_DeInit()
- or HAL_SPI_Init() function.
-
- [..]
- When the compilation define USE_HAL_PPP_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.
-
- [..]
- Using the HAL it is not possible to reach all supported SPI frequency with the different SPI Modes,
- the following table resume the max SPI frequency reached with data size 8bits/16bits,
- according to frequency of the APBx Peripheral Clock (fPCLK) used by the SPI instance.

- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (++) No-Blocking mode: The communication is performed using Interrupts
- or DMA, These APIs return the HAL status.
- The end of the data processing will be indicated through the
- dedicated SPI IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_SPI_TxCpltCallback(), HAL_SPI_RxCpltCallback() and HAL_SPI_TxRxCpltCallback() user callbacks
- will be executed respectively at the end of the transmit or Receive process
- The HAL_SPI_ErrorCallback()user callback will be executed when a communication error is detected
-
- (#) APIs provided for these 2 transfer modes (Blocking mode or Non blocking mode using either Interrupt or DMA)
- exist for 1Line (simplex) and 2Lines (full duplex) modes.

- * @brief SRAM HAL module driver.
- * This file provides a generic firmware to drive SRAM memories
- * mounted as external device.
- *
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- This driver is a generic layered driver which contains a set of APIs used to
- control SRAM memories. It uses the FSMC layer functions to interface
- with SRAM devices.
- The following sequence should be followed to configure the FSMC to interface
- with SRAM/PSRAM memories:
-
- (#) Declare a SRAM_HandleTypeDef handle structure, for example:
- SRAM_HandleTypeDef hsram; and:
-
- (++) Fill the SRAM_HandleTypeDef handle "Init" field with the allowed
- values of the structure member.
-
- (++) Fill the SRAM_HandleTypeDef handle "Instance" field with a predefined
- base register instance for NOR or SRAM device
-
- (++) Fill the SRAM_HandleTypeDef handle "Extended" field with a predefined
- base register instance for NOR or SRAM extended mode
-
- (#) Declare two FSMC_NORSRAM_TimingTypeDef structures, for both normal and extended
- mode timings; for example:
- FSMC_NORSRAM_TimingTypeDef Timing and FSMC_NORSRAM_TimingTypeDef ExTiming;
- and fill its fields with the allowed values of the structure member.
-
- (#) Initialize the SRAM Controller by calling the function HAL_SRAM_Init(). This function
- performs the following sequence:
-
- (##) MSP hardware layer configuration using the function HAL_SRAM_MspInit()
- (##) Control register configuration using the FSMC NORSRAM interface function
- FSMC_NORSRAM_Init()
- (##) Timing register configuration using the FSMC NORSRAM interface function
- FSMC_NORSRAM_Timing_Init()
- (##) Extended mode Timing register configuration using the FSMC NORSRAM interface function
- FSMC_NORSRAM_Extended_Timing_Init()
- (##) Enable the SRAM device using the macro __FSMC_NORSRAM_ENABLE()
-
- (#) At this stage you can perform read/write accesses from/to the memory connected
- to the NOR/SRAM Bank. You can perform either polling or DMA transfer using the
- following APIs:
- (++) HAL_SRAM_Read()/HAL_SRAM_Write() for polling read/write access
- (++) HAL_SRAM_Read_DMA()/HAL_SRAM_Write_DMA() for DMA read/write transfer
-
- (#) You can also control the SRAM device by calling the control APIs HAL_SRAM_WriteOperation_Enable()/
- HAL_SRAM_WriteOperation_Disable() to respectively enable/disable the SRAM write operation
-
- (#) You can continuously monitor the SRAM device HAL state by calling the function
- HAL_SRAM_GetState()
-
- *** Callback registration ***
- =============================================
- [..]
- The compilation define USE_HAL_SRAM_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- Use Functions @ref HAL_SRAM_RegisterCallback() to register a user callback,
- it allows to register following callbacks:
- (+) MspInitCallback : SRAM MspInit.
- (+) MspDeInitCallback : SRAM MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- Use function @ref HAL_SRAM_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function. It allows to reset following callbacks:
- (+) MspInitCallback : SRAM MspInit.
- (+) MspDeInitCallback : SRAM MspDeInit.
- This function) takes as parameters the HAL peripheral handle and the Callback ID.
-
- By default, after the @ref HAL_SRAM_Init and if the state is HAL_SRAM_STATE_RESET
- all callbacks are reset to the corresponding legacy weak (surcharged) functions.
- Exception done for MspInit and MspDeInit callbacks that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_SRAM_Init
- and @ref HAL_SRAM_DeInit only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_SRAM_Init and @ref HAL_SRAM_DeInit
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
-
- Callbacks can be registered/unregistered in READY state only.
- Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
- in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
- during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_SRAM_RegisterCallback before calling @ref HAL_SRAM_DeInit
- or @ref HAL_SRAM_Init function.
-
- When The compilation define USE_HAL_SRAM_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.

- ==============================================================================
- ##### TIMER Generic features #####
- ==============================================================================
- [..] The Timer features include:
- (#) 16-bit up, down, up/down auto-reload counter.
- (#) 16-bit programmable prescaler allowing dividing (also on the fly) the
- counter clock frequency either by any factor between 1 and 65536.
- (#) Up to 4 independent channels for:
- (++) Input Capture
- (++) Output Compare
- (++) PWM generation (Edge and Center-aligned Mode)
- (++) One-pulse mode output
- (#) Synchronization circuit to control the timer with external signals and to interconnect
- several timers together.
- (#) Supports incremental encoder for positioning purposes
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Initialize the TIM low level resources by implementing the following functions
- depending on the selected feature:
- (++) Time Base : HAL_TIM_Base_MspInit()
- (++) Input Capture : HAL_TIM_IC_MspInit()
- (++) Output Compare : HAL_TIM_OC_MspInit()
- (++) PWM generation : HAL_TIM_PWM_MspInit()
- (++) One-pulse mode output : HAL_TIM_OnePulse_MspInit()
- (++) Encoder mode output : HAL_TIM_Encoder_MspInit()
-
- (#) Initialize the TIM low level resources :
- (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE();
- (##) TIM pins configuration
- (+++) Enable the clock for the TIM GPIOs using the following function:
- __HAL_RCC_GPIOx_CLK_ENABLE();
- (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
-
- (#) The external Clock can be configured, if needed (the default clock is the
- internal clock from the APBx), using the following function:
- HAL_TIM_ConfigClockSource, the clock configuration should be done before
- any start function.
-
- (#) Configure the TIM in the desired functioning mode using one of the
- Initialization function of this driver:
- (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base
- (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an
- Output Compare signal.
- (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a
- PWM signal.
- (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an
- external signal.
- (++) HAL_TIM_OnePulse_Init and HAL_TIM_OnePulse_ConfigChannel: to use the Timer
- in One Pulse Mode.
- (++) HAL_TIM_Encoder_Init: to use the Timer Encoder Interface.
-
- (#) Activate the TIM peripheral using one of the start functions depending from the feature used:
- (++) Time Base : HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT()
- (++) Input Capture : HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT()
- (++) Output Compare : HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT()
- (++) PWM generation : HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT()
- (++) One-pulse mode output : HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT()
- (++) Encoder mode output : HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA(), HAL_TIM_Encoder_Start_IT().
-
- (#) The DMA Burst is managed with the two following functions:
- HAL_TIM_DMABurst_WriteStart()
- HAL_TIM_DMABurst_ReadStart()
-
- *** Callback registration ***
- =============================================
-
- [..]
- The compilation define USE_HAL_TIM_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- [..]
- Use Function @ref HAL_TIM_RegisterCallback() to register a callback.
- @ref HAL_TIM_RegisterCallback() takes as parameters the HAL peripheral handle,
- the Callback ID and a pointer to the user callback function.
-
- [..]
- Use function @ref HAL_TIM_UnRegisterCallback() to reset a callback to the default
- weak function.
- @ref HAL_TIM_UnRegisterCallback takes as parameters the HAL peripheral handle,
- and the Callback ID.
-
- [..]
- These functions allow to register/unregister following callbacks:
- (+) Base_MspInitCallback : TIM Base Msp Init Callback.
- (+) Base_MspDeInitCallback : TIM Base Msp DeInit Callback.
- (+) IC_MspInitCallback : TIM IC Msp Init Callback.
- (+) IC_MspDeInitCallback : TIM IC Msp DeInit Callback.
- (+) OC_MspInitCallback : TIM OC Msp Init Callback.
- (+) OC_MspDeInitCallback : TIM OC Msp DeInit Callback.
- (+) PWM_MspInitCallback : TIM PWM Msp Init Callback.
- (+) PWM_MspDeInitCallback : TIM PWM Msp DeInit Callback.
- (+) OnePulse_MspInitCallback : TIM One Pulse Msp Init Callback.
- (+) OnePulse_MspDeInitCallback : TIM One Pulse Msp DeInit Callback.
- (+) Encoder_MspInitCallback : TIM Encoder Msp Init Callback.
- (+) Encoder_MspDeInitCallback : TIM Encoder Msp DeInit Callback.
- (+) HallSensor_MspInitCallback : TIM Hall Sensor Msp Init Callback.
- (+) HallSensor_MspDeInitCallback : TIM Hall Sensor Msp DeInit Callback.
- (+) PeriodElapsedCallback : TIM Period Elapsed Callback.
- (+) PeriodElapsedHalfCpltCallback : TIM Period Elapsed half complete Callback.
- (+) TriggerCallback : TIM Trigger Callback.
- (+) TriggerHalfCpltCallback : TIM Trigger half complete Callback.
- (+) IC_CaptureCallback : TIM Input Capture Callback.
- (+) IC_CaptureHalfCpltCallback : TIM Input Capture half complete Callback.
- (+) OC_DelayElapsedCallback : TIM Output Compare Delay Elapsed Callback.
- (+) PWM_PulseFinishedCallback : TIM PWM Pulse Finished Callback.
- (+) PWM_PulseFinishedHalfCpltCallback : TIM PWM Pulse Finished half complete Callback.
- (+) ErrorCallback : TIM Error Callback.
- (+) CommutationCallback : TIM Commutation Callback.
- (+) CommutationHalfCpltCallback : TIM Commutation half complete Callback.
- (+) BreakCallback : TIM Break Callback.
-
- [..]
-By default, after the Init and when the state is HAL_TIM_STATE_RESET
-all interrupt callbacks are set to the corresponding weak functions:
- examples @ref HAL_TIM_TriggerCallback(), @ref HAL_TIM_ErrorCallback().
-
- [..]
- Exception done for MspInit and MspDeInit functions that are reset to the legacy weak
- functionalities in the Init / DeInit only when these callbacks are null
- (not registered beforehand). If not, MspInit or MspDeInit are not null, the Init / DeInit
- keep and use the user MspInit / MspDeInit callbacks(registered beforehand)
-
- [..]
- Callbacks can be registered / unregistered in HAL_TIM_STATE_READY state only.
- Exception done MspInit / MspDeInit that can be registered / unregistered
- in HAL_TIM_STATE_READY or HAL_TIM_STATE_RESET state,
- thus registered(user) MspInit / DeInit callbacks can be used during the Init / DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_TIM_RegisterCallback() before calling DeInit or Init function.
-
- [..]
- When The compilation define USE_HAL_TIM_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available and all callbacks
- are set to the corresponding weak functions.

- * @file stm32f1xx_hal_tim_ex.c
- * @author MCD Application Team
- * @brief TIM HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Timer Extended peripheral:
- * + Time Hall Sensor Interface Initialization
- * + Time Hall Sensor Interface Start
- * + Time Complementary signal break and dead time configuration
- * + Time Master and Slave synchronization configuration
- * + Timer remapping capabilities configuration
- @verbatim
- ==============================================================================
- ##### TIMER Extended features #####
- ==============================================================================
- [..]
- The Timer Extended features include:
- (#) Complementary outputs with programmable dead-time for :
- (++) Output Compare
- (++) PWM generation (Edge and Center-aligned Mode)
- (++) One-pulse mode output
- (#) Synchronization circuit to control the timer with external signals and to
- interconnect several timers together.
- (#) Break input to put the timer output signals in reset state or in a known state.
- (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for
- positioning purposes
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Initialize the TIM low level resources by implementing the following functions
- depending on the selected feature:
- (++) Hall Sensor output : HAL_TIMEx_HallSensor_MspInit()
-
- (#) Initialize the TIM low level resources :
- (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE();
- (##) TIM pins configuration
- (+++) Enable the clock for the TIM GPIOs using the following function:
- __HAL_RCC_GPIOx_CLK_ENABLE();
- (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
-
- (#) The external Clock can be configured, if needed (the default clock is the
- internal clock from the APBx), using the following function:
- HAL_TIM_ConfigClockSource, the clock configuration should be done before
- any start function.
-
- (#) Configure the TIM in the desired functioning mode using one of the
- initialization function of this driver:
- (++) HAL_TIMEx_HallSensor_Init() and HAL_TIMEx_ConfigCommutEvent(): to use the
- Timer Hall Sensor Interface and the commutation event with the corresponding
- Interrupt and DMA request if needed (Note that One Timer is used to interface
- with the Hall sensor Interface and another Timer should be used to use
- the commutation event).
-
- (#) Activate the TIM peripheral using one of the start functions:
- (++) Complementary Output Compare : HAL_TIMEx_OCN_Start(), HAL_TIMEx_OCN_Start_DMA(), HAL_TIMEx_OC_Start_IT()
- (++) Complementary PWM generation : HAL_TIMEx_PWMN_Start(), HAL_TIMEx_PWMN_Start_DMA(), HAL_TIMEx_PWMN_Start_IT()
- (++) Complementary One-pulse mode output : HAL_TIMEx_OnePulseN_Start(), HAL_TIMEx_OnePulseN_Start_IT()
- (++) Hall Sensor output : HAL_TIMEx_HallSensor_Start(), HAL_TIMEx_HallSensor_Start_DMA(), HAL_TIMEx_HallSensor_Start_IT().

- [..]
- This file must be copied to the application folder and modified as follows:
- (#) Rename it to 'stm32f1xx_hal_timebase_rtc_alarm.c'
- (#) Add this file and the RTC HAL drivers to your project and uncomment
- HAL_RTC_MODULE_ENABLED define in stm32f1xx_hal_conf.h
-
- [..]
- (@) HAL RTC alarm and HAL RTC wakeup drivers can’t be used with low power modes:
- The wake up capability of the RTC may be intrusive in case of prior low power mode
- configuration requiring different wake up sources.
- Application/Example behavior is no more guaranteed
- (@) The stm32f1xx_hal_timebase_tim use is recommended for the Applications/Examples

- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The UART HAL driver can be used as follows:
-
- (#) Declare a UART_HandleTypeDef handle structure (eg. UART_HandleTypeDef huart).
- (#) Initialize the UART low level resources by implementing the HAL_UART_MspInit() API:
- (##) Enable the USARTx interface clock.
- (##) UART pins configuration:
- (+++) Enable the clock for the UART GPIOs.
- (+++) Configure these UART pins (TX as alternate function pull-up, RX as alternate function Input).
- (##) NVIC configuration if you need to use interrupt process (HAL_UART_Transmit_IT()
- and HAL_UART_Receive_IT() APIs):
- (+++) Configure the USARTx interrupt priority.
- (+++) Enable the NVIC USART IRQ handle.
- (##) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA()
- and HAL_UART_Receive_DMA() APIs):
- (+++) Declare a DMA handle structure for the Tx/Rx channel.
- (+++) Enable the DMAx interface clock.
- (+++) Configure the declared DMA handle structure with the required
- Tx/Rx parameters.
- (+++) Configure the DMA Tx/Rx channel.
- (+++) Associate the initialized DMA handle to the UART DMA Tx/Rx handle.
- (+++) Configure the priority and enable the NVIC for the transfer complete
- interrupt on the DMA Tx/Rx channel.
- (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
- (used for last byte sending completion detection in DMA non circular mode)
-
- (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
- flow control and Mode(Receiver/Transmitter) in the huart Init structure.
-
- (#) For the UART asynchronous mode, initialize the UART registers by calling
- the HAL_UART_Init() API.
-
- (#) For the UART Half duplex mode, initialize the UART registers by calling
- the HAL_HalfDuplex_Init() API.
-
- (#) For the LIN mode, initialize the UART registers by calling the HAL_LIN_Init() API.
-
- (#) For the Multi-Processor mode, initialize the UART registers by calling
- the HAL_MultiProcessor_Init() API.
-
- [..]
- (@) The specific UART interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit
- and receive process.
-
- [..]
- (@) These APIs (HAL_UART_Init() and HAL_HalfDuplex_Init()) configure also the
- low level Hardware GPIO, CLOCK, CORTEX...etc) by calling the customized
- HAL_UART_MspInit() API.
-
- ##### Callback registration #####
- ==================================
-
- [..]
- The compilation define USE_HAL_UART_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- [..]
- Use Function @ref HAL_UART_RegisterCallback() to register a user callback.
- Function @ref HAL_UART_RegisterCallback() allows to register following callbacks:
- (+) TxHalfCpltCallback : Tx Half Complete Callback.
- (+) TxCpltCallback : Tx Complete Callback.
- (+) RxHalfCpltCallback : Rx Half Complete Callback.
- (+) RxCpltCallback : Rx Complete Callback.
- (+) ErrorCallback : Error Callback.
- (+) AbortCpltCallback : Abort Complete Callback.
- (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
- (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
- (+) MspInitCallback : UART MspInit.
- (+) MspDeInitCallback : UART MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- [..]
- Use function @ref HAL_UART_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function.
- @ref HAL_UART_UnRegisterCallback() takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) TxHalfCpltCallback : Tx Half Complete Callback.
- (+) TxCpltCallback : Tx Complete Callback.
- (+) RxHalfCpltCallback : Rx Half Complete Callback.
- (+) RxCpltCallback : Rx Complete Callback.
- (+) ErrorCallback : Error Callback.
- (+) AbortCpltCallback : Abort Complete Callback.
- (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
- (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
- (+) MspInitCallback : UART MspInit.
- (+) MspDeInitCallback : UART MspDeInit.
-
- [..]
- By default, after the @ref HAL_UART_Init() and when the state is HAL_UART_STATE_RESET
- all callbacks are set to the corresponding weak (surcharged) functions:
- examples @ref HAL_UART_TxCpltCallback(), @ref HAL_UART_RxHalfCpltCallback().
- Exception done for MspInit and MspDeInit functions that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_UART_Init()
- and @ref HAL_UART_DeInit() only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_UART_Init() and @ref HAL_UART_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
-
- [..]
- Callbacks can be registered/unregistered in HAL_UART_STATE_READY state only.
- Exception done MspInit/MspDeInit that can be registered/unregistered
- in HAL_UART_STATE_READY or HAL_UART_STATE_RESET state, thus registered (user)
- MspInit/DeInit callbacks can be used during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_UART_RegisterCallback() before calling @ref HAL_UART_DeInit()
- or @ref HAL_UART_Init() function.
-
- [..]
- When The compilation define USE_HAL_UART_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available
- and weak (surcharged) callbacks are used.
-
- [..]
- Three operation modes are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Send an amount of data in blocking mode using HAL_UART_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_UART_Receive()
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Send an amount of data in non blocking mode using HAL_UART_Transmit_IT()
- (+) At transmission end of transfer HAL_UART_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_UART_TxCpltCallback
- (+) Receive an amount of data in non blocking mode using HAL_UART_Receive_IT()
- (+) At reception end of transfer HAL_UART_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_UART_RxCpltCallback
- (+) In case of transfer Error, HAL_UART_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_UART_ErrorCallback
-
- *** DMA mode IO operation ***
- ==============================
- [..]
- (+) Send an amount of data in non blocking mode (DMA) using HAL_UART_Transmit_DMA()
- (+) At transmission end of half transfer HAL_UART_TxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_UART_TxHalfCpltCallback
- (+) At transmission end of transfer HAL_UART_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_UART_TxCpltCallback
- (+) Receive an amount of data in non blocking mode (DMA) using HAL_UART_Receive_DMA()
- (+) At reception end of half transfer HAL_UART_RxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_UART_RxHalfCpltCallback
- (+) At reception end of transfer HAL_UART_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_UART_RxCpltCallback
- (+) In case of transfer Error, HAL_UART_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_UART_ErrorCallback
- (+) Pause the DMA Transfer using HAL_UART_DMAPause()
- (+) Resume the DMA Transfer using HAL_UART_DMAResume()
- (+) Stop the DMA Transfer using HAL_UART_DMAStop()
-
- *** UART HAL driver macros list ***
- =============================================
- [..]
- Below the list of most used macros in UART HAL driver.
-
- (+) __HAL_UART_ENABLE: Enable the UART peripheral
- (+) __HAL_UART_DISABLE: Disable the UART peripheral
- (+) __HAL_UART_GET_FLAG : Check whether the specified UART flag is set or not
- (+) __HAL_UART_CLEAR_FLAG : Clear the specified UART pending flag
- (+) __HAL_UART_ENABLE_IT: Enable the specified UART interrupt
- (+) __HAL_UART_DISABLE_IT: Disable the specified UART interrupt
- (+) __HAL_UART_GET_IT_SOURCE: Check whether the specified UART interrupt has occurred or not
-
- [..]
- (@) You can refer to the UART HAL driver header file for more useful macros
-
- @endverbatim
- [..]
- (@) Additionnal remark: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits),
- the possible UART frame formats are as listed in the following table:
- +-------------------------------------------------------------+
- | M bit | PCE bit | UART frame |
- |---------------------|---------------------------------------|
- | 0 | 0 | | SB | 8 bit data | STB | |
- |---------|-----------|---------------------------------------|
- | 0 | 1 | | SB | 7 bit data | PB | STB | |
- |---------|-----------|---------------------------------------|
- | 1 | 0 | | SB | 9 bit data | STB | |
- |---------|-----------|---------------------------------------|
- | 1 | 1 | | SB | 8 bit data | PB | STB | |
- +-------------------------------------------------------------+

- [..]
- This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
- in asynchronous mode.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) Stop Bit
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits),
- please refer to Reference manual for possible UART frame formats.
- (++) Hardware flow control
- (++) Receiver/transmitter modes
- (++) Over Sampling Method
- [..]
- The HAL_UART_Init(), HAL_HalfDuplex_Init(), HAL_LIN_Init() and HAL_MultiProcessor_Init() APIs
- follow respectively the UART asynchronous, UART Half duplex, LIN and Multi-Processor configuration
- procedures (details for the procedures are available in reference manuals

- *
-@verbatim
- ===============================================================================
- ##### IO operation functions #####
- ===============================================================================
- This subsection provides a set of functions allowing to manage the UART asynchronous
- and Half duplex data transfers.
-
- (#) There are two modes of transfer:
- (+) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (+) Non-Blocking mode: The communication is performed using Interrupts
- or DMA, these API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated UART IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_UART_TxCpltCallback(), HAL_UART_RxCpltCallback() user callbacks
- will be executed respectively at the end of the transmit or receive process
- The HAL_UART_ErrorCallback()user callback will be executed when a communication error is detected.
-
- (#) Blocking mode API's are :
- (+) HAL_UART_Transmit()
- (+) HAL_UART_Receive()
-
- (#) Non-Blocking mode API's with Interrupt are :
- (+) HAL_UART_Transmit_IT()
- (+) HAL_UART_Receive_IT()
- (+) HAL_UART_IRQHandler()
-
- (#) Non-Blocking mode API's with DMA are :
- (+) HAL_UART_Transmit_DMA()
- (+) HAL_UART_Receive_DMA()
- (+) HAL_UART_DMAPause()
- (+) HAL_UART_DMAResume()
- (+) HAL_UART_DMAStop()
-
- (#) A set of Transfer Complete Callbacks are provided in Non_Blocking mode:
- (+) HAL_UART_TxHalfCpltCallback()
- (+) HAL_UART_TxCpltCallback()
- (+) HAL_UART_RxHalfCpltCallback()
- (+) HAL_UART_RxCpltCallback()
- (+) HAL_UART_ErrorCallback()
-
- (#) Non-Blocking mode transfers could be aborted using Abort API's :
- (+) HAL_UART_Abort()
- (+) HAL_UART_AbortTransmit()
- (+) HAL_UART_AbortReceive()
- (+) HAL_UART_Abort_IT()
- (+) HAL_UART_AbortTransmit_IT()
- (+) HAL_UART_AbortReceive_IT()
-
- (#) For Abort services based on interrupts (HAL_UART_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
- (+) HAL_UART_AbortCpltCallback()
- (+) HAL_UART_AbortTransmitCpltCallback()
- (+) HAL_UART_AbortReceiveCpltCallback()
-
- (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
- Errors are handled as follows :
- (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
- to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
- Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
- and HAL_UART_ErrorCallback() user callback is executed. Transfer is kept ongoing on UART side.
- If user wants to abort it, Abort services should be called by user.
- (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
- This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
- Error code is set to allow user to identify error type, and HAL_UART_ErrorCallback() user callback is executed.
-
- -@- In the Half duplex communication, it is forbidden to run the transmit
- and receive process in parallel, the UART state HAL_UART_STATE_BUSY_TX_RX can't be useful.

- * Peripheral (USART).
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral Control functions
- @verbatim
- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- The USART HAL driver can be used as follows:
-
- (#) Declare a USART_HandleTypeDef handle structure (eg. USART_HandleTypeDef husart).
- (#) Initialize the USART low level resources by implementing the HAL_USART_MspInit() API:
- (##) Enable the USARTx interface clock.
- (##) USART pins configuration:
- (+++) Enable the clock for the USART GPIOs.
- (+++) Configure the USART pins as alternate function pull-up.
- (##) NVIC configuration if you need to use interrupt process (HAL_USART_Transmit_IT(),
- HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
- (+++) Configure the USARTx interrupt priority.
- (+++) Enable the NVIC USART IRQ handle.
- (##) DMA Configuration if you need to use DMA process (HAL_USART_Transmit_DMA()
- HAL_USART_Receive_DMA() and HAL_USART_TransmitReceive_DMA() APIs):
- (+++) Declare a DMA handle structure for the Tx/Rx channel.
- (+++) Enable the DMAx interface clock.
- (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
- (+++) Configure the DMA Tx/Rx channel.
- (+++) Associate the initialized DMA handle to the USART DMA Tx/Rx handle.
- (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
- (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
- (used for last byte sending completion detection in DMA non circular mode)
-
- (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
- flow control and Mode(Receiver/Transmitter) in the husart Init structure.
-
- (#) Initialize the USART registers by calling the HAL_USART_Init() API:
- (++) These APIs configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
- by calling the customized HAL_USART_MspInit(&husart) API.
-
- -@@- The specific USART interrupts (Transmission complete interrupt,
- RXNE interrupt and Error Interrupts) will be managed using the macros
- __HAL_USART_ENABLE_IT() and __HAL_USART_DISABLE_IT() inside the transmit and receive process.
-
- (#) Three operation modes are available within this driver :
-
- *** Polling mode IO operation ***
- =================================
- [..]
- (+) Send an amount of data in blocking mode using HAL_USART_Transmit()
- (+) Receive an amount of data in blocking mode using HAL_USART_Receive()
-
- *** Interrupt mode IO operation ***
- ===================================
- [..]
- (+) Send an amount of data in non blocking mode using HAL_USART_Transmit_IT()
- (+) At transmission end of transfer HAL_USART_TxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_USART_TxCpltCallback
- (+) Receive an amount of data in non blocking mode using HAL_USART_Receive_IT()
- (+) At reception end of transfer HAL_USART_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_USART_RxCpltCallback
- (+) In case of transfer Error, HAL_USART_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_USART_ErrorCallback
-
- *** DMA mode IO operation ***
- ==============================
- [..]
- (+) Send an amount of data in non blocking mode (DMA) using HAL_USART_Transmit_DMA()
- (+) At transmission end of half transfer HAL_USART_TxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_USART_TxHalfCpltCallback
- (+) At transmission end of transfer HAL_USART_TxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_USART_TxCpltCallback
- (+) Receive an amount of data in non blocking mode (DMA) using HAL_USART_Receive_DMA()
- (+) At reception end of half transfer HAL_USART_RxHalfCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_USART_RxHalfCpltCallback
- (+) At reception end of transfer HAL_USART_RxCpltCallback is executed and user can
- add his own code by customization of function pointer HAL_USART_RxCpltCallback
- (+) In case of transfer Error, HAL_USART_ErrorCallback() function is executed and user can
- add his own code by customization of function pointer HAL_USART_ErrorCallback
- (+) Pause the DMA Transfer using HAL_USART_DMAPause()
- (+) Resume the DMA Transfer using HAL_USART_DMAResume()
- (+) Stop the DMA Transfer using HAL_USART_DMAStop()
-
- *** USART HAL driver macros list ***
- =============================================
- [..]
- Below the list of most used macros in USART HAL driver.
-
- (+) __HAL_USART_ENABLE: Enable the USART peripheral
- (+) __HAL_USART_DISABLE: Disable the USART peripheral
- (+) __HAL_USART_GET_FLAG : Check whether the specified USART flag is set or not
- (+) __HAL_USART_CLEAR_FLAG : Clear the specified USART pending flag
- (+) __HAL_USART_ENABLE_IT: Enable the specified USART interrupt
- (+) __HAL_USART_DISABLE_IT: Disable the specified USART interrupt
-
- [..]
- (@) You can refer to the USART HAL driver header file for more useful macros
-
- ##### Callback registration #####
- ==================================
-
- [..]
- The compilation define USE_HAL_USART_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
-
- [..]
- Use Function @ref HAL_USART_RegisterCallback() to register a user callback.
- Function @ref HAL_USART_RegisterCallback() allows to register following callbacks:
- (+) TxHalfCpltCallback : Tx Half Complete Callback.
- (+) TxCpltCallback : Tx Complete Callback.
- (+) RxHalfCpltCallback : Rx Half Complete Callback.
- (+) RxCpltCallback : Rx Complete Callback.
- (+) TxRxCpltCallback : Tx Rx Complete Callback.
- (+) ErrorCallback : Error Callback.
- (+) AbortCpltCallback : Abort Complete Callback.
- (+) MspInitCallback : USART MspInit.
- (+) MspDeInitCallback : USART MspDeInit.
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
-
- [..]
- Use function @ref HAL_USART_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function.
- @ref HAL_USART_UnRegisterCallback() takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) TxHalfCpltCallback : Tx Half Complete Callback.
- (+) TxCpltCallback : Tx Complete Callback.
- (+) RxHalfCpltCallback : Rx Half Complete Callback.
- (+) RxCpltCallback : Rx Complete Callback.
- (+) TxRxCpltCallback : Tx Rx Complete Callback.
- (+) ErrorCallback : Error Callback.
- (+) AbortCpltCallback : Abort Complete Callback.
- (+) MspInitCallback : USART MspInit.
- (+) MspDeInitCallback : USART MspDeInit.
-
- [..]
- By default, after the @ref HAL_USART_Init() and when the state is HAL_USART_STATE_RESET
- all callbacks are set to the corresponding weak (surcharged) functions:
- examples @ref HAL_USART_TxCpltCallback(), @ref HAL_USART_RxHalfCpltCallback().
- Exception done for MspInit and MspDeInit functions that are respectively
- reset to the legacy weak (surcharged) functions in the @ref HAL_USART_Init()
- and @ref HAL_USART_DeInit() only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the @ref HAL_USART_Init() and @ref HAL_USART_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
-
- [..]
- Callbacks can be registered/unregistered in HAL_USART_STATE_READY state only.
- Exception done MspInit/MspDeInit that can be registered/unregistered
- in HAL_USART_STATE_READY or HAL_USART_STATE_RESET state, thus registered (user)
- MspInit/DeInit callbacks can be used during the Init/DeInit.
- In that case first register the MspInit/MspDeInit user callbacks
- using @ref HAL_USART_RegisterCallback() before calling @ref HAL_USART_DeInit()
- or @ref HAL_USART_Init() function.
-
- [..]
- When The compilation define USE_HAL_USART_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registration feature is not available
- and weak (surcharged) callbacks are used.
-
- @endverbatim
- [..]
- (@) Additionnal remark: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits),
- the possible USART frame formats are as listed in the following table:
- +-------------------------------------------------------------+
- | M bit | PCE bit | USART frame |
- |---------------------|---------------------------------------|
- | 0 | 0 | | SB | 8 bit data | STB | |
- |---------|-----------|---------------------------------------|
- | 0 | 1 | | SB | 7 bit data | PB | STB | |
- |---------|-----------|---------------------------------------|
- | 1 | 0 | | SB | 9 bit data | STB | |
- |---------|-----------|---------------------------------------|
- | 1 | 1 | | SB | 8 bit data | PB | STB | |
- +-------------------------------------------------------------+

- ##### Initialization and Configuration functions #####
- ==============================================================================
- [..]
- This subsection provides a set of functions allowing to initialize the USART
- in asynchronous and in synchronous modes.
- (+) For the asynchronous mode only these parameters can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) Stop Bit
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- Depending on the frame length defined by the M bit (8-bits or 9-bits),
- please refer to Reference manual for possible USART frame formats.
- (++) USART polarity
- (++) USART phase
- (++) USART LastBit
- (++) Receiver/transmitter modes
-
- [..]
- The HAL_USART_Init() function follows the USART synchronous configuration
- procedures (details for the procedures are available in reference manuals
- (RM0008 for STM32F10Xxx MCUs and RM0041 for STM32F100xx MCUs)).

- ##### IO operation functions #####
- ==============================================================================
- [..]
- This subsection provides a set of functions allowing to manage the USART synchronous
- data transfers.
-
- [..]
- The USART supports master mode only: it cannot receive or send data related to an input
- clock (SCLK is always an output).
-
- (#) There are two modes of transfer:
- (++) Blocking mode: The communication is performed in polling mode.
- The HAL status of all data processing is returned by the same function
- after finishing transfer.
- (++) No-Blocking mode: The communication is performed using Interrupts
- or DMA, These API's return the HAL status.
- The end of the data processing will be indicated through the
- dedicated USART IRQ when using Interrupt mode or the DMA IRQ when
- using DMA mode.
- The HAL_USART_TxCpltCallback(), HAL_USART_RxCpltCallback() and HAL_USART_TxRxCpltCallback()
- user callbacks
- will be executed respectively at the end of the transmit or Receive process
- The HAL_USART_ErrorCallback() user callback will be executed when a communication
- error is detected
-
- (#) Blocking mode APIs are :
- (++) HAL_USART_Transmit() in simplex mode
- (++) HAL_USART_Receive() in full duplex receive only
- (++) HAL_USART_TransmitReceive() in full duplex mode
-
- (#) Non Blocking mode APIs with Interrupt are :
- (++) HAL_USART_Transmit_IT()in simplex mode
- (++) HAL_USART_Receive_IT() in full duplex receive only
- (++) HAL_USART_TransmitReceive_IT() in full duplex mode
- (++) HAL_USART_IRQHandler()
-
- (#) Non Blocking mode functions with DMA are :
- (++) HAL_USART_Transmit_DMA()in simplex mode
- (++) HAL_USART_Receive_DMA() in full duplex receive only
- (++) HAL_USART_TransmitReceive_DMA() in full duplex mode
- (++) HAL_USART_DMAPause()
- (++) HAL_USART_DMAResume()
- (++) HAL_USART_DMAStop()
-
- (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
- (++) HAL_USART_TxHalfCpltCallback()
- (++) HAL_USART_TxCpltCallback()
- (++) HAL_USART_RxHalfCpltCallback()
- (++) HAL_USART_RxCpltCallback()
- (++) HAL_USART_ErrorCallback()
- (++) HAL_USART_TxRxCpltCallback()
-
- (#) Non-Blocking mode transfers could be aborted using Abort API's :
- (++) HAL_USART_Abort()
- (++) HAL_USART_Abort_IT()
-
- (#) For Abort services based on interrupts (HAL_USART_Abort_IT), a Abort Complete Callbacks is provided:
- (++) HAL_USART_AbortCpltCallback()
-
- (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
- Errors are handled as follows :
- (++) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
- to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
- Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
- and HAL_USART_ErrorCallback() user callback is executed. Transfer is kept ongoing on USART side.
- If user wants to abort it, Abort services should be called by user.
- (++) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
- This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
- Error code is set to allow user to identify error type, and HAL_USART_ErrorCallback() user callback is executed.

- * @brief WWDG HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Window Watchdog (WWDG) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral State functions
- @verbatim
- ==============================================================================
- ##### WWDG specific features #####
- ==============================================================================
- [..]
- Once enabled the WWDG generates a system reset on expiry of a programmed
- time period, unless the program refreshes the counter (downcounter)
- before reaching 0x3F value (i.e. a reset is generated when the counter
- value rolls over from 0x40 to 0x3F).
-
- (+) An MCU reset is also generated if the counter value is refreshed
- before the counter has reached the refresh window value. This
- implies that the counter must be refreshed in a limited window.
- (+) Once enabled the WWDG cannot be disabled except by a system reset.
- (+) WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
- reset occurs.
- (+) The WWDG counter input clock is derived from the APB clock divided
- by a programmable prescaler.
- (+) WWDG clock (Hz) = PCLK1 / (4096 * Prescaler)
- (+) WWDG timeout (mS) = 1000 * Counter / WWDG clock
- (+) WWDG Counter refresh is allowed between the following limits :
- (++) min time (mS) = 1000 * (Counter _ Window) / WWDG clock
- (++) max time (mS) = 1000 * (Counter _ 0x40) / WWDG clock
-
- (+) Min-max timeout value at 36 MHz(PCLK1): 910 us / 58.25 ms
-
- (+) The Early Wakeup Interrupt (EWI) can be used if specific safety
- operations or data logging must be performed before the actual reset is
- generated. When the downcounter reaches the value 0x40, an EWI interrupt
- is generated and the corresponding interrupt service routine (ISR) can
- be used to trigger specific actions (such as communications or data
- logging), before resetting the device.
- In some applications, the EWI interrupt can be used to manage a software
- system check and/or system recovery/graceful degradation, without
- generating a WWDG reset. In this case, the corresponding interrupt
- service routine (ISR) should reload the WWDG counter to avoid the WWDG
- reset, then trigger the required actions.
- Note:When the EWI interrupt cannot be served, e.g. due to a system lock
- in a higher priority task, the WWDG reset will eventually be generated.
-
- (+) Debug mode : When the microcontroller enters debug mode (core halted),
- the WWDG counter either continues to work normally or stops, depending
- on DBG_WWDG_STOP configuration bit in DBG module, accessible through
- __HAL_DBGMCU_FREEZE_WWDG() and __HAL_DBGMCU_UNFREEZE_WWDG() macros
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (+) Enable WWDG APB1 clock using __HAL_RCC_WWDG_CLK_ENABLE().
-
- (+) Set the WWDG prescaler, refresh window, counter value and Early Wakeup
- Interrupt mode using using HAL_WWDG_Init() function.
- This enables WWDG peripheral and the downcounter starts downcounting
- from given counter value.
- Init function can be called again to modify all watchdog parameters,
- however if EWI mode has been set once, it can't be clear until next
- reset.
-
- (+) The application program must refresh the WWDG counter at regular
- intervals during normal operation to prevent an MCU reset using
- HAL_WWDG_Refresh() function. This operation must occur only when
- the counter is lower than the window value already programmed.
-
- (+) if Early Wakeup Interrupt mode is enable an interrupt is generated when
- the counter reaches 0x40. User can add his own code in weak function
- HAL_WWDG_EarlyWakeupCallback().
-
- *** WWDG HAL driver macros list ***
- ==================================
- [..]
- Below the list of most used macros in WWDG HAL driver.
-
- (+) __HAL_WWDG_GET_IT_SOURCE: Check the selected WWDG's interrupt source.
- (+) __HAL_WWDG_GET_FLAG: Get the selected WWDG's flag status.
- (+) __HAL_WWDG_CLEAR_FLAG: Clear the WWDG's pending flags.

- * @brief FSMC Low Layer HAL module driver.
- *
- * This file provides firmware functions to manage the following
- * functionalities of the Flexible Memory Controller (FSMC) peripheral memories:
- * + Initialization/de-initialization functions
- * + Peripheral Control functions
- * + Peripheral State functions
- *
- @verbatim
- ==============================================================================
- ##### FSMC peripheral features #####
- ==============================================================================
- [..] The Flexible memory controller (FSMC) includes following memory controllers:
- (+) The NOR/PSRAM memory controller
- (+) The NAND/PC Card memory controller
-
- [..] The FSMC functional block makes the interface with synchronous and asynchronous static
- memories and 16-bit PC memory cards. Its main purposes are:
- (+) to translate AHB transactions into the appropriate external device protocol
- (+) to meet the access time requirements of the external memory devices
-
- [..] All external memories share the addresses, data and control signals with the controller.
- Each external device is accessed by means of a unique Chip Select. The FSMC performs
- only one access at a time to an external device.
- The main features of the FSMC controller are the following:
- (+) Interface with static-memory mapped devices including:
- (++) Static random access memory (SRAM)
- (++) Read-only memory (ROM)
- (++) NOR Flash memory/OneNAND Flash memory
- (++) PSRAM (4 memory banks)
- (++) 16-bit PC Card compatible devices
- (++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of
- data
- (+) Independent Chip Select control for each memory bank
- (+) Independent configuration for each memory bank

- (+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support
- for three different databus modes: 1-bit (default), 4-bit and 8-bit
- (+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility)
- (+) Full compliance with SD Memory Card Specifications Version 2.0
- (+) Full compliance with SD I/O Card Specification Version 2.0: card support for two
- different data bus modes: 1-bit (default) and 4-bit
- (+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol
- Rev1.1)
- (+) Data transfer up to 48 MHz for the 8 bit mode
- (+) Data and command output enable signals to control external bidirectional drivers
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- This driver is a considered as a driver of service for external devices drivers
- that interfaces with the SDMMC peripheral.
- According to the device used (SD card/ MMC card / SDMMC card ...), a set of APIs
- is used in the device's driver to perform SDMMC operations and functionalities.
-
- This driver is almost transparent for the final user, it is only used to implement other
- functionalities of the external device.
-
- [..]
- (+) The SDMMC clock (SDMMCCLK = 48 MHz) is coming from a specific output (MSI, PLLUSB1CLK,
- PLLUSB2CLK). Before start working with SDMMC peripheral make sure that the
- PLL is well configured.
- The SDMMC peripheral uses two clock signals:
- (++) SDMMC adapter clock (SDMMCCLK = 48 MHz)
- (++) APB2 bus clock (PCLK2)
-
- -@@- PCLK2 and SDMMC_CK clock frequencies must respect the following condition:
- Frequency(PCLK2) >= (3 / 8 x Frequency(SDMMC_CK))
-
- (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC
- peripheral.
-
- (+) Enable the Power ON State using the SDIO_PowerState_ON()
- function and disable it using the function SDIO_PowerState_OFF().
-
- (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros.
-
- (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT()
- and __SDIO_DISABLE_IT() if you need to use interrupt mode.
-
- (+) When using the DMA mode
- (++) Configure the DMA in the MSP layer of the external device
- (++) Active the needed channel Request
- (++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro
- __SDIO_DMA_DISABLE().
-
- (+) To control the CPSM (Command Path State Machine) and send
- commands to the card use the SDIO_SendCommand(),
- SDIO_GetCommandResponse() and SDIO_GetResponse() functions. First, user has
- to fill the command structure (pointer to SDIO_CmdInitTypeDef) according
- to the selected command to be sent.
- The parameters that should be filled are:
- (++) Command Argument
- (++) Command Index
- (++) Command Response type
- (++) Command Wait
- (++) CPSM Status (Enable or Disable).
-
- -@@- To check if the command is well received, read the SDIO_CMDRESP
- register using the SDIO_GetCommandResponse().
- The SDMMC responses registers (SDIO_RESP1 to SDIO_RESP2), use the
- SDIO_GetResponse() function.
-
- (+) To control the DPSM (Data Path State Machine) and send/receive
- data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(),
- SDIO_ReadFIFO(), SDIO_WriteFIFO() and SDIO_GetFIFOCount() functions.
-
- *** Read Operations ***
- =======================
- [..]
- (#) First, user has to fill the data structure (pointer to
- SDIO_DataInitTypeDef) according to the selected data type to be received.
- The parameters that should be filled are:
- (++) Data TimeOut
- (++) Data Length
- (++) Data Block size
- (++) Data Transfer direction: should be from card (To SDMMC)
- (++) Data Transfer mode
- (++) DPSM Status (Enable or Disable)
-
- (#) Configure the SDMMC resources to receive the data from the card
- according to selected transfer mode (Refer to Step 8, 9 and 10).
-
- (#) Send the selected Read command (refer to step 11).
-
- (#) Use the SDIO flags/interrupts to check the transfer status.
-
- *** Write Operations ***
- ========================
- [..]
- (#) First, user has to fill the data structure (pointer to
- SDIO_DataInitTypeDef) according to the selected data type to be received.
- The parameters that should be filled are:
- (++) Data TimeOut
- (++) Data Length
- (++) Data Block size
- (++) Data Transfer direction: should be to card (To CARD)
- (++) Data Transfer mode
- (++) DPSM Status (Enable or Disable)
-
- (#) Configure the SDMMC resources to send the data to the card according to
- selected transfer mode.
-
- (#) Send the selected Write command.
-
- (#) Use the SDIO flags/interrupts to check the transfer status.
-
- *** Command management operations ***
- =====================================
- [..]
- (#) The commands used for Read/Write/Erase operations are managed in
- separate functions.
- Each function allows to send the needed command with the related argument,
- then check the response.
- By the same approach, you could implement a command and check the response.
