Devlog #8
I wrote and compiled the updated firmware.

I got the QMK firmware finished for the final 7-key layout plus the rotary encoder and OLED. I updated keyboard.json to match my actual pinout, then ran into a string of small compile errors working through keymap.c: wrong argument count for LAYOUT() since my key count changed, a stray trailing comma, and using MATRIX_LAYERS which isn’t actually a valid macro in this QMK version, just needed a “1” for a single layer.

I ended up swapping Close Tab for Paste in the final key layout so Copy and Paste are usable together instead of just having Copy on its own. The final layout is New Tab, New Window, Undo, Redo, Refresh, Paste, Copy, with the encoder controlling volume and the OLED showing a static ready message for now.

Challenges:
Getting a clean compile didn’t actually mean the firmware did what I expected, since I realized later that I was still missing the rules.mk file.

Next Steps:
The firmware compiles clean and outputs a working .uf2 file. I’m going to package everything up for submission: Gerbers, case files, firmware, README, and BOM. I might also add some flair to the Tinkercad case to make it more personalized.
