Detailed Description

SPI_CMD_* macros are general command codes for SPI_control(). Not all SPI driver implementations support these command codes.

SPICC26XXDMA_CMD_* macros are command codes only defined in the SPICC26XXDMA.h driver implementation and need to:

#include <ti/drivers/spi/SPICC26XXDMA.h>

Macro Definition Documentation

SPICC26XXDMA_CMD_RETURN_PARTIAL_DISABLE

#define SPICC26XXDMA_CMD_RETURN_PARTIAL_DISABLE   (SPI_CMD_RESERVED + 1)

Command used by SPI_control to disable partial return.

Disabling this command returns the SPICC26XXDMA to the default blocking behavior where SPI_transfer blocks until all data bytes were received. With this command arg is don't care and it returns SPI_STATUS_SUCCESS.

SPICC26XXDMA_CMD_RETURN_PARTIAL_ENABLE

#define SPICC26XXDMA_CMD_RETURN_PARTIAL_ENABLE   (SPI_CMD_RESERVED + 0)

Command used by SPI_control to enable partial return.

Enabling this command allows SPI_transfer to return partial data if the master de-asserts the CS line before the expected number of frames were received. This command arg is of type don't care and it returns SPI_STATUS_SUCCESS or SPI_STATUS_ERROR.

SPICC26XXDMA_CMD_SET_CSN_PIN

#define SPICC26XXDMA_CMD_SET_CSN_PIN   (SPI_CMD_RESERVED + 2)

Command used by SPI_control to re-configure chip select pin.

This command specifies a chip select pin With this command arg is of type PIN_Id and it return SPI_STATUS_SUCCESS
