While I was waiting for my board to come in, I started playing with the screen, learning about Adafruit’s library as well as designing the watch interface and visuals.  I’ve created a Github repository to host all of the test programs, image files, and final code.  I’m currently using a modified Adafruit GFX library and the SdFat library, but will probably strip out the code not required for my application and start using a custom display library soon.
