Tutorial: Control WS2812B leds with STM32 - STM32F4 Discovery
In this tutorial I will explain how to drive WS2812B with STM32 using TIM PWM and DMA peripherals in the most efficient way by using minimum amount of RAM, required to process all leds. There is a good explanation, already available on the web. If you have no experience with WS2812B leds, I strongly recommend you to read the blog post. It is very well written, but it has one major issue. It uses 24 words of RAM for each LED,...
