I've had a week or so to play around with the display. It's easy to use but building GUI elements takes time! I've never appreciated how much work at the basic level is being done on smart phones! Here's a video of my work so far, I'll update with details next week.

Sometime's the best way to get traction in a project is to "just try it". I tend to believe more things can be learned from mistakes than instant successes. With the "lets dive in" cap on, we purchased an Adafruit Assembled Touch TFT module; this one. Pairing with a Teensy 3.1 as the brains behind the operation was easy thanks to Paul Stoffregen's immense work on supporting libraries. The TFT screen has an ILI9341 Controller which has been used quite commonly in the Arduino world. We used a Teensy for the brains for a number of reasons; The spec/price ratio is excellent, the teensy supporting libraries are well put together and supported and, most of all, I have one sitting spare on my desk!
