ad5629r_init()

int8_t ad5629r_init	(	struct ad5629r_dev **	device,
		struct ad5629r_init_param	init_param )

Initializes the communication with the device.

Parameters

device	- AD5629R device structure.
init_param	- Device initial parameters. Example: AD5629R, AD5669R, AD5668, AD5648, AD5628.

Returns

status - Result of the initialization procedure. Example: 0 - if initialization was successful; -1 - if initialization was unsuccessful.

ad5629r_load_clear_code_reg()

void ad5629r_load_clear_code_reg	(	struct ad5629r_dev *	dev,
		uint8_t	clear_value )

Loads the Clear Code Register with a certain value.

Parameters

dev	- The device structure.
clear_value	- the value to be set in all DAC registers after a clear operation. Example: CLR_TO_ZEROSCALE - clears to 0x0; CLR_TO_MIDSCALE - clears to 0x8000; CLR_TO_FULLSCALE - clears to 0xFFFF; CLR_NOOP - no operation.

ad5629r_load_ldac_reg()

void ad5629r_load_ldac_reg	(	struct ad5629r_dev *	dev,
		uint8_t	dac_sel )

Loads the LDAC register with a certain value.

Parameters

dev	- The device structure.
dac_sel	- a byte where each bit is corresponding to a DAC; when a bit is set to 1, the corresponding DAC is selected to override LDAC pin. Example: DAC_A_SEL - the selected DAC to override the LDAC pin is DAC A; DAC_D_SEL | DAC_F_SEL | DAC_H_SEL - the selected DACs to override the LDAC pin are: DAC D, DAC F and DAC H.

ad5629r_remove()

int32_t ad5629r_remove

(

struct ad5629r_dev *

dev

)

Parameters

dev	- The device structure.

Returns

ret - The result of the remove procedure.

ad5629r_reset()

void ad5629r_reset

(

struct ad5629r_dev *

dev

)
