ad9656_JESD204_test()

int32_t ad9656_JESD204_test	(	struct ad9656_dev *	dev,
		uint32_t	test_mode
	)

Launch the JESD204 test functionality for the receive path for the ad9656 chip.

Parameters

dev	- The device handler for the ad9656 chip
test_mode	- The type of test that is to be performed or OFF if the testing process is to be stopped

Returns

0 if the ad9656 chip could be successfully set for JESD204 link testing, -1 otherwise

Here is the caller graph for this function:

ad9656_reg_read()

int32_t ad9656_reg_read	(	struct ad9656_dev *	dev,
		uint16_t	reg_addr,
		uint8_t *	reg_data
	)

Reads from the ad9656 that is contected to the SPI.

Parameters

dev	- The ad9656 device handler
reg_addr	- The address of the internal register of the ad9656 chip
reg_data	- The value read from the internal register

Returns

0 if the value was successfully read, -1 otherwise

Here is the caller graph for this function:

ad9656_reg_write()

int32_t ad9656_reg_write	(	struct ad9656_dev *	dev,
		uint16_t	reg_addr,
		uint8_t	reg_data
	)

Write to the ad9656 that is conected to the SPI.

Parameters

dev	- The device handler for the ad9656 chip
reg_addr	- Address of the internal register of the ad9656 chip
reg_data	- Value to be written to the register

Returns

0 if the value was written successfully, -1 otherwise

Here is the caller graph for this function:

ad9656_remove()

int32_t ad9656_remove

(

struct ad9656_dev *

dev

)

Free the resources allocated by ad9656_setup().

Parameters

dev	- The device structure.

Returns

0 in case of success, negative error code otherwise.

ad9656_setup()

int32_t ad9656_setup	(	struct ad9656_dev **	device,
		const struct ad9656_init_param *	init_param
	)

Setup the working parameters of the ad9656 chip.

Parameters

device	- The device handler of the ad9656 chip
init_param	- Values for the working parameters of ad9656

Returns

0 if device is ready for use, -1 otherwise

Here is the caller graph for this function:

ad9656_user_input_test()

int32_t ad9656_user_input_test	(	struct ad9656_dev *	dev,
		uint32_t	test_mode,
		struct ad9656_user_input_test_pattern	user_input_test_pattern
	)

Launch the user input test functionality for the receive path for the ad9656 chip. User input data is supplied on the outputs instead of real data captured on the ADC.

Parameters

dev	- The device handler for the ad9656 chip
test_mode	- The type of test that is to be performed or OFF if the testing process is to be stopped
user_input_test_pattern	- User input test pattern that is sent on the output instead of the ADC data

Returns

0 if the ad9656 chip could be successfully set for user input testing, FAILURE otherwise
