Reset source code to work as keyboard
- Make changes to .ioc file and save it
- Build the code
- Delete the Middlewares folder
- Unzip Middlewares KEYBOARD SETUP.zip and rename the folder to Middlewares (Keep the ziped file here for future use)
- Build the code (there will likely be errors, if so proceed to step 6)
- Navigate to Drivers>STM32F4xx_HAL_DRIVER>Src in this directory there will be duplicate files that look like this
...cortex.cand...cortext 2.cor...cortex 3.cto fix this delete all of the files that have a number at the end of the file name. This can easily be done in the console/terminal withrm *2.corrm *3.c

Questions
How big is the KBT1 PCB?
It measures 90 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KBT1 use?
37 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the KBT1 KiCad files?
From the zobelj/ECE477 repository on GitHub, at the commit this page was made from: the board is KBT1/KBT1.kicad_pcb and its schematic ESD Protection Circuit/ESD Protection Circuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KBT1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask zobelj before reusing the design.
