I am debugging a SPI connection with another device. I am using the NANO for the project. I want an extra serial port to assist with debugging so I switched to the MEGA. This code works correctly on the NANO: #include <digitalWriteFast.h> #include <SPI.h> #define DATAOUT 11//MOSI #define DATAIN 1…

SPI issues... works on the NANO, not on the MEGA. Pin numbers are right. Ideas?

nope, he's got the pins right: SPI - Arduino Reference

Oops. Now I feel silly.
