I just got a HyperPIxel Raspberry Pi touch-screen LCD display from Pimoroni. This neat display is the same size as the Raspberry Pi itself, and covers all its GPIO pins but it is a touchscreen and it does shift 800×480 pixel video at 60 frames a second. I have plans to do something with a camera and this screen, but as a first project I fell back to my standard: can I make a radio from it?
Being a touch screen, some kind of GUI would be a good idea, and the project I hacked together gave me an excuse to play with Tkinter, the default, but far from ideal, GUI toolkit that Python has installed by default.
I had problems getting the HyperPixel to work at first – I had to do a clean install of Raspbian Jesse, presumably because some other project was interfering with some of the GPIO pins.
