Function Documentation

sx1509b_led_intensity_pin_configure()

int sx1509b_led_intensity_pin_configure	(	const struct device *	dev,
		gpio_pin_t	pin
	)

Configure a pin for LED intensity.

Configure a pin to be controlled by SX1509B LED driver using the LED intensity functionality. To get back normal GPIO funcionality, configure the pin using the standard GPIO API.

Parameters

dev	Pointer to the device structure for the driver instance.
pin	Pin number.

Return values

0	If successful.
-EWOULDBLOCK	if function is called from an ISR.
-ERANGE	if pin number is out of range.
-EIO	if I2C fails.

sx1509b_led_intensity_pin_set()

int sx1509b_led_intensity_pin_set	(	const struct device *	dev,
		gpio_pin_t	pin,
		uint8_t	intensity_val
	)

Set LED intensity of selected pin.

Parameters

dev	Pointer to the device structure for the driver instance.
pin	Pin number.
intensity_val	Intensity value.

Return values

0	If successful.
-EIO	if I2C fails.
