This file is used by the [QMK API](https://github.com/qmk/qmk_api). It contains the information [QMK Configurator](https://config.qmk.fm/) needs to display a representation of your keyboard. You can also set metadata here.
You can create `info.json` files at every level under `qmk_firmware/keyboards/<name>` to specify this metadata. These files are combined, with more specific files overriding keys in less specific files. This means you do not need to duplicate your metadata information. For example, `qmk_firmware/keyboards/clueboard/info.json` specifies `manufacturer` and `maintainer`, while `qmk_firmware/keyboards/clueboard/66/info.json` specifies more specific information about Clueboard 66%.
## `info.json` Format
The `info.json` file is a JSON formatted dictionary with the following keys available to be set. You do not have to set all of them, merely the keys that apply to your keyboard.
*`keyboard_name`
* A free-form text string describing the keyboard.
* Example: `Clueboard 66%`
*`url`
* A URL to the keyboard's product page, [QMK.fm/keyboards](https://qmk.fm/keyboards) page, or other page describing information about the keyboard.
*`maintainer`
* GitHub username of the maintainer, or `qmk` for community maintained boards
* How many milliseconds (ms) to wait for debounce to happen. (Default: 5)
*`diode_direction`
* The direction diodes face. See [`DIRECT_PINS` in the hardware configuration](https://docs.qmk.fm/#/config_options?id=hardware-options) for more details.
*`layout_aliases`
* A dictionary containing layout aliases. The key is the alias and the value is a layout in `layouts` it maps to.
Within our `info.json` file the `layouts` portion of the dictionary contains several nested dictionaries. The outer layer consists of QMK layout macros, for example `LAYOUT_ansi` or `LAYOUT_iso`. Within each layout macro are keys for `width`, `height`, and `key_count`, each of which should be self-explanatory.
Each Key Dictionary in a layout describes the physical properties of a key. If you are familiar with the Raw Code for <https://keyboard-layout-editor.com> you will find many of the concepts the same. We re-use the same key names and layout choices wherever possible, but unlike keyboard-layout-editor each key is stateless, inheriting no properties from the keys that came before it.
* This should usually correspond to the keycode for the first layer of the default keymap.
*`matrix`
* A 2 item list describing the row and column location for this key.
### Matrix Pins
Currently QMK supports connecting switches either directly to GPIO pins or via a switch matrix. At this time you can not combine these, they are mutually exclusive.
#### Switch Matrix
Most keyboards use a switch matrix to connect keyswitches to the MCU. You can define your pin columns and rows to configure your switch matrix. When defining switch matrices you should also define your `diode_direction`.
Example:
```json
{
"diode_direction": "COL2ROW",
"matrix_pins": {
"cols": ["F4", "E6", "B1", "D2"],
"rows": ["B0", "D3", "D5", "D4", "D6"]
}
}
```
#### Direct Pins
Direct pins are when you connect one side of the switch to GND and the other side to a GPIO pin on your MCU. No diode is required, but there is a 1:1 mapping between switches and pins.
When specifying direct pins you need to arrange them in nested arrays. The outer array consists of rows, while the inner array is a text string corresponding to a pin. You can use `null` to indicate an empty spot in the matrix.
This section controls the legacy WS2812 support in QMK. This should not be confused with the RGB Matrix feature, which can be used to control both WS2812 and ISSI RGB LEDs.
The following items can be set. Not every value is required.
*`led_count`
* The number of LEDs in your strip
*`pin`
* The GPIO pin that your LED strip is connected to
*`animations`
* A dictionary that lists enabled and disabled animations. See [RGB Light Animations](#rgb_light_animations) below.
*`sleep`
* Set to `true` to enable lighting during host sleep
*`split`
* Set to `true` to enable synchronization functionality between split halves
*`split_count`
* For split keyboards, the number of LEDs on each side
*`max_brightness`
* (0-255) What the maxmimum brightness (value) level is
*`hue_steps`
* How many steps of adjustment to have for hue
*`saturation_steps`
* How many steps of adjustment to have for saturation
*`brightness_steps`
* How many steps of adjustment to have for brightness (value)
Example:
```json
{
"rgblight": {
"led_count": 4,
"pin": "F6",
"hue_steps": 10,
"saturation_steps": 17,
"brightness_steps": 17,
"animations": {
"all": true
}
}
}
```
#### RGB Light Animations
The following animations can be enabled:
| Key | Description |
|-----|-------------|
| `all` | Enable all additional animation modes. |
