Hello, I am going to use Arduino Uno Wifi Rev2 to program an external ATMEGA4809 microcontroller using Arduino IDE. However, I’ve used more than 13 digital and 6 analog pins used in Arduino. Thus, I need to define pins as ports specified at ATMEGA4809 datasheet (e.g. PA6, PC4 etc.). How can I achieve that? Thank you.
Have you looked at MCUdude's MegaCoreX, is has support for all the pins of the atmega4809.
