Am slowly making indirect progress, but very slowly. I've got an Intel Edison, and figured out toggling of GPIOs via the MRAA C/C++ library (and via python), once I learned what the mapping in software was for the GPIOs. Useful reference page to that end: https://github.com/intel-iot-devkit/mraa/blob/master/docs/edison.md

I'm now working towards getting an Arduino form-factor TFT 2.8" LCD working. I've not messed with LCDs whatsoever before, so I assume some amount of what I learn will be useful. The Edidoom project seems to be the best documented interfacing of a TFT LCD with an Edison, so I've been gradually digesting its workings. I'll probably end up with (sound-less) DOOM running. I'm using somewhat different hardware than in that project, so that will force me to learn some things as I go, rather than just copying and running code/wiring. http://2ld.de/edidoom/

I've yet to get around to doing the simple little custom PCB for monitoring what's happening on the ribbon cables. It's a boring unappealing step for me, I guess.

I also did more disassembly. Got the screen half pried apart as well. Finally sated my curiosity (of 5 years and running) as to how the two-way hinge works. Cool stuff. I've got pics, but haven't bothered to upload them anywhere (sorry!).
