-  ==============================================================================

-                        ##### How to use this driver #####

-  ==============================================================================

-  [..]

-    The IRDA HAL driver can be used as follows:

-

-    (#) Declare a IRDA_HandleTypeDef handle structure.

-    (#) 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 the 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

-  @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 |     |

-  ==============================================================================

-    [..]

-    This subsection provides a set of functions allowing to initialize the USARTx or the UARTy 

-    in 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).

-  [..]

-    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.  

-        (++) 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 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
