I'm new to Arduino but I have some experience with developing hardware based on AVR MCUs.
I've been playing around with my Due and the Arduino IDE and tried out some of the examples. All worked just fine.
But then I tried to use the Embedded Artists E-Paper 2.7" E-Paper display (rev c) with the Due and I just can't get it to work. The display is suited for use with 3.3 volts. Embedded Artists provides an example Arduino sketch and the required libraries for the Uno here: http://www.embeddedartists.com/sites/default/files/support/displays/epaper/Epaper_arduino.pdf
I connected all PINs exactly like explained in the pdf. I just changed MISO, MOSI and SCK to the dedicated ICSP-connector of the Due (in contrast to the Uno, the Due seems to not pin out the SPI to the pins on the side of the board). I selected a SPI connection divider of 21 (84/21 = 4 MHz, which is the recommended SPI frequency).
When running the sketch on the due, the images on the display should change frequently. But nothing happens, except for the "power" lights on the back of the display's board being on.
Do I miss any differences between the Due and the Uno that could help here? Or does anyone have experience with the combination of the Due and the display?
