Typedefs
typedef int(*	led_api_update_rgb) (const struct device *dev, struct led_rgb *pixels, size_t num_pixels)
	Callback API for updating an RGB LED strip.
typedef int(*	led_api_update_channels) (const struct device *dev, uint8_t *channels, size_t num_channels)
	Callback API for updating channels without an RGB interpretation.
typedef size_t(*	led_api_length) (const struct device *dev)

Functions
static int	led_strip_update_rgb (const struct device *dev, struct led_rgb *pixels, size_t num_pixels)
	Mandatory function to update an LED strip with the given RGB array.
static int	led_strip_update_channels (const struct device *dev, uint8_t *channels, size_t num_channels)
	Optional function to update an LED strip with the given channel array (each channel byte corresponding to an individually addressable color channel or LED.
static size_t	led_strip_length (const struct device *dev)
	Mandatory function to get chain length (in pixels) of an LED strip device.

Detailed Description

Main header file for LED strip driver API.

This library abstracts the chipset drivers for individually addressable strips of LEDs.
