Very nice!
Could you post the connection scheme between the adapter and the microcontroller? I see 28 pins, but not all are connected
It's all in the source code, referenced to the pin numbers that I give on my PCB. Note, the numbers don't follow the conventional numbering scheme, but it works if you go by them. Check out the source code comments and constants.
