Function Documentation

adis1657x_read_burst_data()

int adis1657x_read_burst_data	(	struct adis_dev *	adis,
		struct adis_burst_data *	data,
		bool	burst32,
		uint8_t	burst_sel,
		bool	fifo_pop,
		bool	crc_check )

Read burst data.

Parameters

adis	- The adis device.
data	- The burst read data structure to be populated.
burst32	- True if 32-bit data is requested for accel and gyro (or delta angle and delta velocity) measurements, false if 16-bit data is requested.
burst_sel	- 0 if accel and gyro data is requested, 1 if delta angle and delta velocity is requested.
fifo_pop	- In case FIFO is present, will pop the fifo if true. Unused if FIFO is not present.
crc_check	- If true CRC will be checked, if false check will be skipped.

Returns

0 in case of success, error code otherwise. -EAGAIN in case the request has to be sent again due to data being unavailable at the time of the request.
