As part of my road test with the sama5d3, I've been working on a simple graphics library using Python, currently it consists of an lcd driver and buffer, a bmp decoder, a simple shape library and a simple system text library.
Heres a video of it in action:
Ive attached the libraries and a readme file that shows the commands I've used in the video. Feel free to use and modify the libraries for your own needs, I'm continuing development myself too and if they seem to be worthwhile in the future will upload them to a github account.
