Data Structure Documentation

struct spi_rtos_handle_t

Data Fields
SPI_Type *	base
	SPI base address.

spi_master_handle_t	drv_handle
	Handle of the underlying driver, treated as opaque by the RTOS layer.

SemaphoreHandle_t	mutex
	Mutex to lock the handle during a trasfer.

SemaphoreHandle_t	event
	Semaphore to notify and unblock task when transfer ends.

#define FSL_SPI_FREERTOS_DRIVER_VERSION (MAKE_VERSION(2, 1, 0))

This function initializes the SPI module and related RTOS context.

Parameters

handle	The RTOS SPI handle, the pointer to an allocated space for RTOS context.
base	The pointer base address of the SPI instance to initialize.
masterConfig	Configuration structure to set-up SPI in master mode.
srcClock_Hz	Frequency of input clock of the SPI module.

status_t SPI_RTOS_Deinit ( spi_rtos_handle_t * handle )

This function deinitializes the SPI module and related RTOS context.

Parameters

handle The RTOS SPI handle.

This function performs an SPI transfer according to data given in the transfer structure.

Parameters

handle	The RTOS SPI handle.
transfer	Structure specifying the transfer parameters.
