Using STM32 MCU bluepill or blackpill, STM32CubeIDE, send GPIO signal, non-DMA method, to control a WS2811 RGB IC, to light up the 3 RGB leds of a RGB LCD screen.
There are already quite a few tutorials for such topic but most of them are using DMA. I am not using DMA since it's not suitable for my project, and, probably non DMA is easier in my use case.
Detail steps for how to make this work
