New Version of Pi-Radio running under Jessie.  Removed Pygame, some buttons, button size is larger and I rotated the screen 180 for better placement.

Beaglebone Black (BBB) with tft_320qvt Touchscreen Parallel Bus

Steps to Wire and Configure the TFT_320QVT touch screen using the BBB parallel bus.  There are lots of examples for the SPI bus, but I thought it could be interesting to try the parallel bus. 
For the touchscreen, I had trouble to load the DT overlay via the command line but was able to get it to work via uEnv.txt.  I don' know why it is like this, but I've raised the question here:  https://groups.google.com/forum/#!topic/beagleboard/gOynYr8fgns

Jessie, Pygame and TFT touch screens (Raspberry Pi) and Calibration

It has been raining a lot so I tried to update my Pi-radio project.  It doesn't work and I'd been better off standing outside in the rain.  The calibration is way-off and the touch screen is unusable at best.  I suspect a lot of people will be in this situation.
