Specification In order for VIA to configure a keyboard, it requires a definition of the keyboard - the physical layout of keys, any layout options, and other configurable elements like rotary encoders (knobs), lighting, etc.

VIA Version 3 is a refactoring of how the UI works in VIA, to allow fully customized UI within VIA to control firmware parameters like lighting, but also any custom feature implemented in the firmware, either in QMK Core or at the keyboard level.

Custom UI Introduction The built-in menus of VIA (Keymap, Layouts, Macros, Save + Load) will be displayed depending on keyboard definition and firmware. The menus element is used to define more menus in VIA. It can contain one or more of the following built-in UI definitions: qmk_audio qmk_backlight_rgblight qmk_backlight qmk_rgb_matrix qmk ...

[ { "label": "Audio", "content": [ { "label": "General", "content": [ { "label": "Audio Enable", "type": "toggle", "content": ["id_qmk_audio_enable", 4, 1 ...

VIA works by communicating with the firmware that is running on the device and sending it commands across USB. Enabling the VIA feature in QMK enables both the ability to communicate with the VIA Configurator and the ability to store keymaps and other settings.

VIA requires a definition of both the physical arrangement of keys and the mapping of those keys to the switch matrix. It optionally requires definition of layout options - alternative physical arrangements of keys, such as different bottom rows, split right shift, etc.
