Kegboard Arduino Firmware

When I down load the Arduino software and try to load the sketch using Arduino IDE when I do a compile I am receiving errors such as “ Compilation error: util/crc16.h:

No such file or directory”

Any idea what I have done wrong or didn’t complete??

Thanks for any help

Been ages since I have done it, from memory I didn’t use the arduino ide I was using a flashing tool. There are probably a million ways to do this now, I see there is a web flasher someone has built but I think this is the one I used to use - Flash Download Tool User Guide - ESP32 - — ESP Test Tools latest documentation

I’ve just built a new kegbot from scratch. I used the mega 2560 and flashed it with the Arduino ide.

what is the problem you were having?
