Function Documentation

adxl355_iio_init()

int adxl355_iio_init	(	struct adxl355_iio_dev **	iio_dev,
		struct adxl355_iio_dev_init_param *	init_param
	)

Initializes the ADXL355 IIO driver.

Parameters

iio_dev	- The iio device structure.
init_param	- The structure that contains the device initial parameters.

Returns

ret - Result of the initialization procedure.

Here is the caller graph for this function:

adxl355_iio_remove()

int adxl355_iio_remove

(

struct adxl355_iio_dev *

desc

)

Free the resources allocated by adxl355_iio_init().

Parameters

desc	- The IIO device structure.

Returns

ret - Result of the remove procedure.

adxl355_read_device_data()

int adxl355_read_device_data	(	struct adxl355_dev *	dev,
		uint8_t	base_address,
		uint16_t	size,
		uint8_t *	read_data
	)

Reads from the device.

Parameters

dev	- The device structure.
base_address	- Address of the base register.
size	- The number of bytes to be read and returned in read_data.
read_data	- The read data buffer

Returns

ret - Result of the reading procedure.

Here is the caller graph for this function:

adxl355_write_device_data()

int adxl355_write_device_data	(	struct adxl355_dev *	dev,
		uint8_t	base_address,
		uint16_t	size,
		uint8_t *	write_data
	)

Writes to the device.

Parameters

dev	- The device structure.
base_address	- Address of the base register.
size	- The number of bytes to be written. It is the size of the write_data buffer.
write_data	- The data which is going to be written.

Returns

ret - Result of the writing procedure.
