Detailed Description

Data transfers functions.

  ==============================================================================
                      ##### IO operation functions #####
 ===============================================================================
 [..]
    This subsection provides a set of functions allowing to manage the SPI
    data transfers.

    [..] The SPI supports master and slave mode :

    (#) 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 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.

Function Documentation

HAL_StatusTypeDef HAL_SPI_Abort

(

SPI_HandleTypeDef *

hspi

)

Abort ongoing transfer (blocking mode).

Parameters:

hspi	SPI handle.

Note:

This procedure could be used for aborting any ongoing transfer (Tx and Rx), started in Interrupt or DMA mode. This procedure performs following operations :

• Disable SPI Interrupts (depending of transfer direction)
• 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.

Once transfer is aborted, the __HAL_SPI_CLEAR_OVRFLAG() macro must be called in user application before starting new SPI receive process.

Return values:

HAL_StatusTypeDef HAL_SPI_Abort_IT

(

SPI_HandleTypeDef *

hspi

)

Abort ongoing transfer (Interrupt mode).

Parameters:

hspi	SPI handle.

Note:

This procedure could be used for aborting any ongoing transfer (Tx and Rx), started in Interrupt or DMA mode. This procedure performs following operations :

• Disable SPI Interrupts (depending of transfer direction)
• Disable the DMA transfer in the peripheral register (if enabled)
• Abort DMA transfer by calling HAL_DMA_Abort_IT (in case of transfer in DMA mode)
• Set handle State to READY
• At abort completion, call user abort complete callback

This procedure is executed in Interrupt mode, meaning that abort procedure could be considered as completed only when user abort complete callback is executed (not when exiting function).

Once transfer is aborted, the __HAL_SPI_CLEAR_OVRFLAG() macro must be called in user application before starting new SPI receive process.
