Задержки у драйвера WS2812 сделаны на fifo шины к GPIO-ports. Это не всегда работает правильно.
Hi pvvx
Great job code works perfectly
fit the control handle up to 1024 pixels ws2812 thank you very much. Will you help me please even modify the code for protocol ArtNet ? I modified the code for a 4 Universe and worked well but I would also like to use it to your code.
here is the original code:
