Function Documentation

◆ sx1509b_led_intensity_pin_configure()

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

#include <include/zephyr/drivers/gpio/gpio_sx1509b.h>

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 functionality, 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.

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