This is a bitbang library for WS2812. I test it with STM32F411RE (Nucleo 441RE). If you want to use another board, u need to adjust the sum of asm("nop"). In the example program i put some code to measure how many asm("nop") do we need. See more detail about WS2812 timing https://cdn-shop.adafruit.com/datasheets/WS2812.pdf
