Function Documentation

adis16607_fifo_enable()

int adis16607_fifo_enable	(	struct adis_dev *	adis,
		bool	enable,
		uint16_t	thr,
		bool	burst32 )

Enable or disable FIFO mode.

Parameters

adis	- The adis device.
enable	- True to enable FIFO, false to disable.
thr	- FIFO watermark threshold (1-1024). Ignored if enable is false.
burst32	- True for 32-bit burst mode, false for 16-bit. Ignored if enable is false.

Returns

0 in case of success, error code otherwise.

adis16607_fifo_pop()

int adis16607_fifo_pop	(	struct adis_dev *	adis,
		struct adis_burst_data *	data )

Pop one sample from the FIFO.

Parameters

adis	- The adis device.
data	- The burst read data structure to be populated.

Returns

0 in case of success, error code otherwise.

For I2C and SPI Half-Duplex: uses burst read with FIFO_DATA command. For SPI Full-Duplex: issues repeated read commands to FIFO_DATA register. Note: burst32 mode is configured via adis16607_fifo_enable().
