I cannot fix this compilation error:

D:\B_Up ACER\Documents\ELECTRONICS\ESP32C3_sketch_A02yy\ESP32C3_sketch_A02yy.ino:17:10: fatal error: avr/interrupt.h: No such file or directory
#include <avr/interrupt.h>
^~~~~~~~~~~~~~~~~
compilation terminated.
exit status 1

Compilation error: avr/interrupt.h: No such file or directory

Please help!

 

Not a lot of information to go on but have you installed the AVR boards?

If that doesn't help. give us the link to the sketch you copied.

Umm, I just tried to compile an empty sketch with that line added and it fails too. 

We will need to see the original code and context.

So I loaded up ArduinoIDE 1.8.9 and the sketch compiled and uploaded perfectly. 😉

  Mode 1 is set by bridging "M1" pads on board

Gee! it would be nice if Arduino provided a list of things that they break when the do an upgrade of the IDE. 😡 

I am coming to the conclusion that IDE versions, board versions and managers, libraries are a giant maze! Oh how I wish that there was something better.

@miken58 Ummm, the ver 1 IDE has not been upgraded in many years. All the stuff you mention is common to both IDE's. Not being a professional programmer you will not know that an IDE is simply a fancy GUI that invokes the command line program comon to both IDE's and uses all the same libraries and even most of the misc files.

The board manager is simple, it's something you usually do once to install a new board like the recent UNO R4. Libraries of course we are adding and possiblt removing fairly often.

I will admit choosing one of several similar sounding libraries is part science, part art. If in doubt, ask. Experienced folks know some of the authors so if you have a choice of two and one is by Khoi Hoang and is to do with comms, then that is likely a good choice.

Please read the help and learn how to post code, thank you.

I just noticed, you appear to be working with an ESP32C3 board, but the avr libraries are Arduino ONLY! See attached pic

@miken58 Is your issue resolved? I plan on stepping away from the forum but want to close any outstanding issues.
