After a whole day soldering yesterday, ending up with a wire mess.
Which didn’t work at the end…
Starting measuring some things, and create some test sketches (led blinky tests)
I found out that the main problem was not having the red switches connected to GND.
Blue switches where upside down, this was a easy fix. Because these are ON-ON switches, and where already connected to a common line.
Then a mixup between D0 and D6 (wires crossed)
And it is working! Made some lines and lettering on the frontplate after some playing around.
Weird to input stuff in octal (group of 3 bits)
