STM32 WS2812 (NeoPixel RGB LED)

When developing the STM32Dev board a WS2812B RGB LED was including connected to the PC6 GPIO.

The WS2812B LED contains 3 LEDS: red, green and blue and each of these LEDS can be set at 256 different brightness levels. These levels are controlled with a bit stream running at 800 kHz and multiple LEDS (up to 1000-ish) can be chained after each other.
