(+) __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 | | - +-------------------------------------------------------------+ - ****************************************************************************** -

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. - -@endverbatim - * @{ - */ - -/** - * @brief Sends an amount of data in blocking mode. - * @note When UART parity is not enabled (PCE = 0), and Word Length is configured to 9 bits (M1-M0 = 01), - * the sent data is handled as a set of u16.
