you are right, i haven't found any project that uses PIC18F4550/2550 to inspire from it; only with uses ESP32 which i'm not familiar...yet,
i'm already convinced that i should go for ESP32;

theese config words worked for me, with an external OSC 20Mhz, Flowcode V5; config Words PIC18F4550 USB and external OSC.png was succesfully recognised from windows 11 as universal USB Serial converter; my project is simple but i dont find some working examples about, i need to activate and deactiva...
