Function Documentation

led_strip_update_channels()

static int led_strip_update_channels ( const struct device *  dev, uint8_t *  channels, size_t  num_channels  )

inlinestatic

#include <zephyr/drivers/led_strip.h>

Update an LED strip on a per-channel basis.

Important: This routine may overwrite channels.

This routine immediately updates the strip display according to the given channels array. Each channel byte corresponds to an individually addressable color channel or LED. Channels are updated linearly in strip order.

Parameters

dev	LED strip device
channels	Array of per-channel data
num_channels	Length of channels array

Returns

0 on success, negative on error

Warning

May overwrite channels

led_strip_update_rgb()

static int led_strip_update_rgb ( const struct device *  dev, struct led_rgb *  pixels, size_t  num_pixels  )

inlinestatic

#include <zephyr/drivers/led_strip.h>

Update an LED strip made of RGB pixels.

Important: This routine may overwrite pixels.

This routine immediately updates the strip display according to the given pixels array.

Parameters

dev	LED strip device
pixels	Array of pixel data
num_pixels	Length of pixels array

Returns

0 on success, negative on error

Warning

May overwrite pixels
