There may have been easier ways to go about this but I didn't want to have to bake my own firmware and I've already used the Easy AVR GUI for my KMAC2.
Anyway, I poked around the config files of Easy AVR and added a layout to the phantom config for the The Still Unamed Split TKL:
Loading it came out like this:
Fixed the key map on the Normal layer:
Work-in-progress FN layer:
Work-in-progress FN2 layer:
I took note of the row and columns that Easy AVR was expecting from the keys and ended up with this diagram for rows and columns (note to self, add wiring):
To Do:
- transcribe the matrix row and columns in reverse since when I do the soldering, I will be looking at the keyboard from the bottom
Edit: fixed image sizes
