An easily reconfigurable macro keyboard that can press button combinations, like ALT+Tab. Suitable for using for shortcuts in a program, or for activating Auto-hotkey scripts.
Built with the Raspberry Pi Pico and CircuitPython.
- A Raspberry Pi Pico
- Some keyboard switches (I used Durock T1 67g Tactile).
- Key caps for the switches (I used Tai-hao rubber keycaps).
- An enclosure (if you have access to a 3D printer - this design worked for me:
novaspirit#[email protected], when I printed the lid with a skirt for adhesion, which suppressed deformations)
See the fritzing schematics on how to assemble the keyboard (very simple).
The microcontroller was programmed with CircuitPython 7.0.0-rc.1.
- Download it from here: https://circuitpython.org/board/raspberry_pi_pico/
- Hold the BOOTSEL button while plugging in the Pico.
- Drop the CircuitPython.uf2 file in the Pico's CIRCUITPYTHON drive.
- Initialize the code in this repository (clone submodules etc.):
$ ./install.sh Cloning external submodules/libs Copying external libs into pico libs folder
- Copy all files from the pico folder to your CircuitPython drive.
- Unplug the Pico from the USB port, and plug it in again. Voilà!
- Add mappings to config.json for the pins to key combinations. The file shall contain an array. Each element is an array of strings. Each string is the name of a key to press. The entry shall be null to leave the key unconfigured. E.g.
[ ["A"], // Key 1 presses a (note that it is just the key, not the upper case character) null, // Key 2 does not press any key combination ["ALT", "Tab"], // Key 3 pressed ALT+Tab // The rest of the keys are not configured ]
- Hold down GP0 upon boot to enable only-keyboard mode
- If any key is held down during boot, then the program will exit (as a kill-switch in case there is a short)
