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
SUCCESS 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.
Returns
None.
