ltc3220_test_led_quick_write_with_indiv()

int ltc3220_test_led_quick_write_with_indiv	(	struct ltc3220_dev *	ltc3220,
		enum ltc3220_uled_mode	mode )

Parallel and Serial LED control. LED 2 to 9 are set to serial, then LED1 is set to display on all LEDs. After some delay LED 9 to 18 will change mode in serial write.

Parameters

ltc3220	- the device structure.
mode	- the mode to set the individual LEDs

Returns

0 in case of success, negative error code otherwise.

ltc3220_test_led_singles()

int ltc3220_test_led_singles	(	struct ltc3220_dev *	ltc3220,
		enum ltc3220_uled_mode	mode )

individual LED control for all 18 LEDs

Parameters

ltc3220	- The device structure.
mode	- the mode to set all the LEDs to.

Returns

0 in case of success, negative error code otherwise.

ltc3220_test_led_singles_alt_modes()

int ltc3220_test_led_singles_alt_modes

(

struct ltc3220_dev *

ltc3220

)

individual LED control with alternating modes for all 18 LEDs

Parameters

ltc3220

- the device structure.

Returns

0 in case of success, negative error code otherwise.
