Function Documentation

Sensor_SPI_BlockWrite()

int32_t Sensor_SPI_BlockWrite	(	ARM_DRIVER_SPI *	pCommDrv,
		registerDeviceInfo_t *	devInfo,
		void *	pWriteParams,
		const registercommandlist_t *	pCommandList,
		uint8_t	error_mask
	)

Write commands to a sensor.

The interface function to write register data to a sensor.

Validate for the correct handle.

Update register values based on register write list unless the next Cmd is the list terminator

Write the command based on the values in the command and value pair.

Wait for Command Completion.
