After much screwing around, I finally got the ST7565 working with the Arduino Due. The wonderful u8glib recently added support for the Due and had preexisting support for the ST7565. I'm still annoyed that I can't get the adafruit library to work on the Due. I'm slowly porting bits of the u8glib SAM code path for the ST7565 over, but frankly I'm just annoyed with displays at this point, so I'm going to go on the something more interesting, like actually adding a clock to my alarm clock.
I've spent the last several days unsuccessfully trying to get the ST7565 to work with the Arduino Due. I've been trying to port ladyada's ST7565 library to the SAM core without much luck. Using the ST7565 with Uno and the library works with no issues, as would be expected, so I didn't fuck up soldering or anything easy to diagnose like that. Getting the code to run on the Due is not as easy.
One of the things I knew going into this project was that I wanted the alarm clock to be compatible with Arduino. Ideally I'm going to expose as many of the Arduino's pins on the final product in an accessible way so people can slap on shields and extend the clock to make it better. This then begs the question: which Arduino? I have both a Uno and a Due. While I like the simplicity, support and cost of the Uno, the Due seems more future proof.
