Detailed Description

IRDA Transmit/Receive functions.

 ===============================================================================
                      ##### 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.  
       (++) 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

    (#) Blocking mode API's 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()

    (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
        (++) HAL_IRDA_TxCpltCallback()
        (++) HAL_IRDA_RxCpltCallback()
        (++) HAL_IRDA_ErrorCallback()

Function Documentation

HAL_StatusTypeDef HAL_IRDA_Abort ( IRDA_HandleTypeDef * hirda )

Abort ongoing transfers (blocking mode).

Parameters:

hirda IRDA handle.

Note:

This procedure could be used for aborting any ongoing transfer started in Interrupt or DMA mode. This procedure performs following operations :

Disable PPP Interrupts
Disable the DMA transfer in the peripheral register (if enabled)
Abort DMA transfer by calling HAL_DMA_Abort (in case of transfer in DMA mode)
Set handle State to READY

This procedure is executed in blocking mode : when exiting function, Abort is considered as completed.
