I am succesfully running Pixy2 on Arduino Uno but when I try on an Arduino Nano 33 IoT board it fails.
Simply including these headers gives the following errors:
#include <SPI.h>
#include <Pixy2.h>
Full, error dump bellow.
Do I need a different library that is compatible with that hardware?
FYI ( I am the beginner )
