Hi, has anyone had success using the Arduino DUE with the shield?
I’ve been able to successfully get my little controller pedal working with switches, knobs and an LCD display using an Arduino UNO and the Arduino shield (as long as I’m not over-ambitious in trying to have too many actuators!). So I ordered an Arduino DUE hoping that it would be pretty much a drop in replacement for the UNO and I could then have up to 8 actuators.
I modified variant.cpp in the arduino_due_x folder to add the weak attribute as per the instructions .
But when I connect the DUE to the shield instead of the UNO the MOD DUO doesn’t recognise it at all.
I’ve unsoldered everything from the hat just in case that should cause problems, but no joy.
Should it just work or are there other changes I need to make? This blog post give the impression that it should just work.
I’ve discovered that the standard I2C pins that I was using to drive the LCD have moved to pins 20 & 21. Has anything else changed? Do I need to recompile anything (other than my own sketch) after changing variant.cpp?
