Hand-wired 12 keys macro with Vial firmware
While browsing for the next keyboard build, I stumbled upon this macro pad from thingiverse. I wanted to create a macro pad that would used for streaming but also used for developing and other misc stuff. I decided to use the Vial firmware so I can change the keys and macros on the fly.
- 3d printed stream deck
- 12 Cherry MX switches
- One Pro Micro
- Wires, Female/Male jumper wires
- 12 Cherry MX keycaps, if you don't want to print the keycaps
- rubber feet, if you didn't print the non-slip pad which needs TPU material
Following the Hand-wiring Guide from the QMK firmware documentation, this is how I wired up the macro pad with the controller.
Primary reason for not permanently soldering the key switches to the controller, is to give the option to change the controller or key switches. I'd like to one day try to put a nice!nano controller.
It is important to wire the controller accordingly, the firmware is coded for the specific pins as the rows and columns:
...
#define MATRIX_ROW_PINS { D4, C6, D7 }
#define MATRIX_COL_PINS { F4, F5, F6, F7 }
...Refer to the Pro Micro pinout for more details. Otherwise make sure you update the matrix row/col pins in the config.h file.
Vial firmware is a fork form the QMK firmware, but allows you to use a host gui to change the key mappings on the fly. More about the firmware can be found here: get.vial.today
Clone my firmware: https://github.com/greyhatmiddleman/vial-qmk.git
git clone --recurse-submodules https://github.com/greyhatmiddleman/vial-qmk.git
The firmware is located in keyboards/12keys/keymaps/vial
Remember there is no need to update keymaps.c file, you will be changing your keymaps from the vial application.
qmk flash -kb 12keys -km vial
After you've flashed the firmware, install the Vial host gui from here. For more instructions follow the first time use guide
Connect the macro pad, run the application and you should be all set.
- All the cool Vial features!!!
- Make sure your macro pad and connected based on the pin configuration
- Connect the macro pad before running the application, otherwise click on refresh
- Use a Nice!Nano controller, but will lose the Vial functionality.
- Add oled to display current layer.
