Hi,

I’m new bee in Arduino, I need Help To Convert ATtiny2331 Firmware to ATMEGA328 using Arduino IDE.

Please find attached files for the reference. Please help me to covert, Thanks in advance.

I think if that was my problem I would create an empty setup() function and change the name of your main() function to void loop() and then try to compile it with the Arduino IDE so I could see what error messages it throws up. Then work on eliminating the errors starting with the first one the compiler detects.

Also, I think I would initially compile it on the Arduino IDE for the Attiny2331 and only convert to the 328 when I had the bugs out.
