I fixed the code and the schematic.

I took the TM1637 4 digit display module I used for my 8042 clock and a test program written in C instead of assembler. After a bit of adjustment of the code (again I missed a bit transition in the protocol) I got it to display the desired numbers.

So now I can release the board design on Github and the rest of the project will be getting the software working.
