@felmue said in Core 2 and COMMU: I agree, it can be a bit frustrating at times but on the bright side you will probably learn some new skills, like reading and understanding schematics. I am positive you'll figure it out. Of course, I have been playing with Arduino and ESP8266 / 32 for 3 years and several years ago with the PIC16 ... and all my pleasure is to learn and to discover. I have already read many schematics and created myself some PCBs for my project. Thank you Felix
