Function Documentation

ad7303_init()

int8_t ad7303_init	(	struct ad7303_dev **	device,
		struct ad7303_init_param	init_param )

Initializes SPI communication.

Initializes SPI communication.

Parameters

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

Returns

Result of the initialization procedure. Example: -1 - SPI peripheral was not initialized. 0 - SPI peripheral is initialized.

ad7303_remove()

int32_t ad7303_remove

(

struct ad7303_dev *

dev

)

Free the resources allocated by ad7303_init().

Free the resources allocated by ad7303_init().

Parameters

dev	- The device structure.

Returns

0 in case of success, negative error code otherwise.

ad7303_write()

void ad7303_write	(	struct ad7303_dev *	dev,
		uint8_t	control_reg,
		uint8_t	data_reg )

Sends data to AD7303.

Sends data to ad7303.

Parameters

dev	- The device structure.
control_reg	- Value of control register. Example: AD7303_INT | AD7303_LDAC | AD7303_A - enables internal reference and loads DAC A input register from shift register and updates both DAC A and DAC B DAC registers.
data_reg	- Value of data register.
