a DIY attempt of a 68 key style mechanical keyboard which not only looks cool, but can also scan at 1000 Hz
click the image below to watch the build video on youtube.
This keyboard is powered with a STM32F401CC board (a.k.a black pill F401CC)
To build this project, simply clone this project and build it in vscode with PlatformIO IDE
Note : Before building and flashing to the microcontroller, make sure that the keyboard wiring matches this schematic
or instead change the matrix pin definitions in src/main.c (rowPins and colPins) to fit your wiring while paying attention to the key mapping in src/keymap.c
"secret" features:
- AutoType mode: The keyboard will turn into an automatic text typer configured to output a specific text defined in src/text.c. Each key press will send a character of the text, and a long press will send the characters continuously. Enable autotype mode by pressing and holding FN and all five right-most keys.
- AutoPress mode: The keyboard will repeatedly press and unpress the enabled key(s). Enable autopress mode by defining ENABLE_AUTOTYPER in src/main.c (definition has been commented out). Flash the new firmware. Then, on the keyboard, press FN, and the key desired (a key without an alternate mode to avoid conflict with alternate key). Then a long press will repeatedly send the desired key. Disable it by again pressing FN and the desired key, or to disable it for the entire keyboard, press FN and ESC
