I’m sticking with my atmega4809 board (I think, but things can change…). I’m reverting (is that the right word?) to programming it in the arduino framework. However, my project will be constructed using a chip and components. So I have gone back to a PIO.ini that worked for me with the atmega328 i.e. my arduino code compiled successfully. If I keep everything the same except for the line in PIO which describes the board and I change that to the line below:
board = ATmega4809
When I now compile the same code, I get this error:
Error: Unknown board ID ‘ATmega4809’
So I checked in the PIO home page and searched for the 4809 and it is listed.
Any help much appreciated
