Thanks Brennan :-) I have various STM32 and nRF52 boards. But at this point I am working with ESP32. The problem I am facing now is that ws2812 application does not want to open /dev/led_rgb device for some reason while gpio application works fine with that dev. So its not yet really timing related. Most likely a messed up custom board / build / peripherals configuration? :-P -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
