Hello All, I want to build a custom ECU with an Arduino Mega Pro. How do I discover which I/O digital and analogue pins
are assigned to which functions? I have the source code downloaded and the Arduino IDE installed. The Speeduino manual mentions looking at the utilities.ino file but it makes no sense to me. All help and advice gratefully received.
TIA,
Dave.

The pin functions depend on which board is selected. The function definitions are in Init.cpp from lines 1361 on . You will see the different boards listed, these are the board types you select in TS.
