    Unfortunately I wasn't able to get the example to compile for my Teensy 3.2 (*) but it compiles fine if I select an Arduino Uno as board.

    If anybody got it to work, I'd be very interested in the solution

    Thanks,
    Marius

    *) an error in the Adafruit_EPD library during compiling:
    Code:
    [...]arduino_build_555710/libraries/Adafruit_EPD/Adafruit_IL0373.cpp.o: In function `Adafruit_IL0373::display()':
    [...]/Documents/Arduino/libraries/Adafruit_EPD/Adafruit_IL0373.cpp:193: undefined reference to `Adafruit_EPD::fastSPIwrite(unsigned char)'
