I’ve got a weird issue that I can’t fix. I’ve got an Arduino wifi Rev 2 and I can’t use the RFID library with it. The Arduino wifi is working and I have uploaded other codes on it (like blink works).
Basically, as soon as I type “#include <MFRC522.h>” in a new sketch I can’t compile it. The weird thing is if I switch the board (in the Tools menu) to like a Mega it compiles just fine.
I get a warning which states:
WARNING: library rfid claims to run on avr, STM32F1, teensy architecture(s) and may be incompatible with your current board which runs on megaavr architecture(s).
Is this the problem? If it is what should I do?
