Mark Williams has written a tutorial in which he downloads and compiles an alternate X-windows desktop environment called ‘matchbox-desktop’. It is a very minimal environment but works well with small touchscreens such as the PiTFT or the PiScreen. Read the tutorial here.
Mark is currently running a Kickstarter campaign for BerryIMU which is a tiny combined accelerometer, gyroscope and magnetometer. I want to put one on the Picorder, so I’m very keen that it succeeds. Take a look at the campaign here.
