Definition in file sensor_io_spi.h.

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.

Parameters

[in]	pCommDrv	pointer to the I2C ARM driver to use.
[in]	devInfo	The SPI device number and idle function.
[in]	pWriteParams	The SPI slave slect handle of the sensor to write to.
[in]	pCommandList	A list of one or more commands to write.
[in]	error_mask	The mask for Error Code Bits in CoCo Byte.

Returns

returns the execution status of the operation using ESensorErrors

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.

		registerDeviceInfo_t *	devInfo,
		void *	pReadParams,
		const registerreadlist_t *	pReadList,
		uint8_t *	pOutBuffer
	)

Read register data from a sensor.

Parameters

[in]	pCommDrv	Pointer to the SPI ARM driver to use.
[in]	devInfo	The SPI device number and idle function.
[in]	pReadParams	SPI slave Params read from.
[in]	pReadList	A list of one or more register addresses and lengths to read.
[in]	pOutBuffer	A pointer of sufficient size to contain the requested read data.

Returns

returns the execution status of the operation using ESensorErrors

The interface function to read register data from a sensor.

Validate for the correct handle.

Traverse the read list and read the registers one by one unless the register read list numBytes is zero
