I think that the best part of this for me is that they managed to map pins 5-12 to match the screen SPI pins. I suppose that once you have a ground pin, the rest can be mapped in software (with the power being a high output), but it's still pretty cool to see.

Author here, thanks! What I'm doing in the code is outputting 1 to the VCC pin and 0 to GND, and that seems to be enough:

yeah, that definitely makes sense. I'll have to start doing that when I connect screens or sensors: much cleaner, thanks for the inspiration!
