QMK Compiler Keyboard Suppport

By default the template that QMK Compiler has is very limited. You can only specify a keymap and can not reference macros or custom keys. QMK Compiler lets you specify information about your keyboard so that configurator apps can make use of them.

Keyboard Metadata

To aid Web and GUI programs that wish to use this API we are publishing metadata about keyboards. You can use this metadata to get information about the keyboard like Manufacturer, Product and Vendor ID's, Processor, and more. This data is populated from the qmk_firmware repository.

Available Metadata

Keymap Templates

QMK Compiler builds a keymap based on the layout you submit in your JSON payload. To do it makes use of a template file to generate that keymap.

Default Template

This is the default template that QMK Compiler uses:


// Helpful defines
#define _______ KC_TRNS

const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {

Supplying Your Own Template

If you'd like to supply a custom template you can do so. Create a directory named templates inside your keyboard's directory, next to keymaps. If QMK Compiler finds a file named keymap.c it will use that as your keyboard's template. Make sure that you have the string __KEYMAP_GOES_HERE__ inside your template so QMK Compiler knows where to insert the keymap.

You can’t perform that action at this time.
