arduino read port
Yesterday I tried to read PORTD port register on an Arduino Mega2560. I found some docs saying that this port is mapped from the pin 38 to 45. ,I want to use port pin of DUE as an input, i worked on mega there we write DDR and PINA to read the port A data. how do i write the same code ...
