Hello,
I am starting a migration from 328PU on a propietary PCB, running nice.
For that project I used the IDE numbers provided in this document:
The Definitive Arduino UNO Pinout Diagram. That document clearly shows the relationship between Pin Function and IDE programming Names (Numbers from 0 to 19, drawn in pink)
Question is: where to get a similar pinout for ATMega 4809 PF DIP-40
BTW, Bootloader and Program loading via Tx/Rx working nice and fast.
Thanks in advance,
