2 :name: PWM RGB LED
5 Drive an RGB LED using the PWM API.
10 This is a sample app which drives an RGB LED using the :ref:`PWM API <pwm_api>`.
12 There are three single-color component LEDs in an RGB LED. Each component LED
15 flicker fusion threshold (the minimum flicker rate where the LED is perceived as
16 being steady). The sample causes each LED component to step from dark to max
17 brightness. Three **for** loops (one for each component LED) generate a gradual
18 range of color changes from the RGB LED, and the sample repeats forever.
25 The LED PWM channels must be configured using the following :ref:`devicetree

10 This sample application demonstrates basic usage of the LED strip.
15 Zephyr supports various LED strip chips. For example,
17 - WS2812, such as the `NeoPixel(WS2812 compatible) LED Strip from AdaFruit`_.
18 - APA102, such as the `Dotstar(APA102 compatible) LED Strip from AdaFruit`_.
19 - LPD8806, such as the `LPD8806 LED Strip from AdaFruit`_.
21 - Power supply. These LED strips usually require a 5V supply.
23 - If the LED strip connects to the SPI bus, SPI communications usually use 5V
