STM32 WS2812 compatible RGBW Controller

This repo contains code for controlling WS2812 compatible RGBW leds using an STM32 microcontroller.

Note: Requires libopencm3 to work.

SPI is used to allow the hardware to manage timing for us - although we do have to craft bytes to conform to the wierd format used by these LEDs.

USB serial is used to print status.

TODO

Implement configuration via USB serial
Implement hardware DMA so that we don't have to stay in the SPI loop while updating the LEDs
