There have been some discussions in the Papilio forum about getting some low cost TFT touchscreens working with the Papilio.
Lee has been working on some touchscreens and that inspired us to pick up work on a Prototype Wing that we had laying around. We were able to get the touchscreen up and running with the Adafruit tft library and here is the result:
Everything works pretty well but before we make a Wing available we are going to have to make a new revision that places the 16-bit data bus in a more convenient to use configuration. This will hopefully only take a couple weeks, keep watching for updates.
