Having a nice case is all well and good but something needs to go in it. The competitions didn't need the deck to actually be built, but since the prize was a resin printed case, I felt I would need to build it anyway.
So to start with My Pi+TFT combo was already built, it just needed an OS setting up and would need the IoT pHAT setting up. should be simple, the pHAT has the eeprom for setting itself up on powerup. I'd just have to connect all the appropriate lines to the broken out pin headers on the TFT board.
They are not in the regular Pi connector 40-pin layout though so some hand wiring needed to be done. Just need to find which ones needed to be connected. No biggie.
I yoinked an SD card from one of my other Pi's set up as a Gameboy Zero which has a similar SPI screen connected in an identical way so that I can test the screen still actually works.
