CRC Polynomial if CRC enabled
Call the function HAL_SPI_DeInit() to restore the default configuration of the selected
SPIx peripheral.
This section contains the following APIs:
HAL_SPI_Init()
HAL_SPI_DeInit()
HAL_SPI_MspInit()
HAL_SPI_MspDeInit()
43.2.3 IO operation functions
This subsection provides a set of functions allowing to manage the SPI data transfers.
The SPI supports master and slave mode :
1. 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
2. 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.
This section contains the following APIs:
HAL_SPI_Transmit()
HAL_SPI_Receive()
