||||
|
||||
Some behaviors have properties to adjust how they behave. These can also be used as templates to create custom behaviors when none of the built-in behaviors do what you want. |
||||
|
||||
See [Configuration Overview](/docs/config/index) for instructions on how to change these settings. |
||||
|
||||
See the [zmk/app/dts/behaviors/](https://github.com/zmkfirmware/zmk/tree/main/app/dts/behaviors) folder for all default behaviors. |
||||
|
||||
## Hold-Tap |
||||
|
||||
Creates a custom behavior that triggers one behavior when a key is held or a different one when the key is tapped. |
||||
|
||||
See the [hold-tap behavior documentation](/docs/behaviors/hold-tap) for more details and examples. |
||||

## Kconfig |
||||
|
||||
Definition file: [zmk/app/Kconfig](https://github.com/zmkfirmware/zmk/blob/main/app/Kconfig) |
||||
|
||||
| Config | Type | Description | Default | |
||||
| ------------------------------------- | ---- | -------------------------------------------------------------- | ------- | |
||||
| `CONFIG_ZMK_COMBO_MAX_PRESSED_COMBOS` | int | Maximum number of combos that can be active at the same time | 4 | |

| `CONFIG_ZMK_COMBO_MAX_COMBOS_PER_KEY` | int | Maximum number of active combos that use the same key position | 5 | |
||||
| `CONFIG_ZMK_COMBO_MAX_KEYS_PER_COMBO` | int | Maximum number of keys to press to activate a combo | 4 | |
||||
|
||||
If `CONFIG_ZMK_COMBO_MAX_COMBOS_PER_KEY` is 5, you can have 5 separate combos that use position `0`, 5 combos that use position `1`, and so on. |
||||
|
||||
If you want a combo that triggers when pressing 5 keys, you must set `CONFIG_ZMK_COMBO_MAX_KEYS_PER_COMBO` to 5. |
||||
|
||||
## Devicetree |
||||
|
||||
Applies to: `compatible = "zmk,combo"` |
||||
|
||||
Definition file: [zmk/app/dts/bindings/zmk,combos.yaml](https://github.com/zmkfirmware/zmk/blob/main/app/dts/bindings/zmk%2Ccombos.yaml) |
||||
|
||||
The `zmk,combos` node itself has no properties. It should have one child node per combo. |
||||
|
||||
Each child node can have the following properties: |
||||
|
||||
| Property | Type | Description | Default | |
||||
| --------------- | ------------- | ---------------------------------------------------------------------------------- | ------- | |
||||
| `bindings` | phandle-array | A [behavior](/docs/features/keymaps#behaviors) to run when the combo is triggered | | |
||||
| `key-positions` | array | A list of key position indices for the keys which should trigger the combo | | |
||||
| `timeout-ms` | int | All the keys must be pressed within this time in milliseconds to trigger the combo | 50 | |
||||
| `slow-release` | bool | Releases the combo when all keys are released instead of when any key is released | false | |
||||
| `layers` | array | A list of layers on which the combo may be triggered. `-1` allows all layers. | `<-1>` | |
||||
|
||||
The `key-positions` array must not be longer than the `CONFIG_ZMK_COMBO_MAX_KEYS_PER_COMBO` setting, which defaults to 4. If you want a combo that triggers when pressing 5 keys, then you must change the setting to 5. |

||||
|
||||
ZMK has several configuration settings that can be changed to change the behavior of your keyboard. They are set in either Kconfig or Devicetree files. |
||||
|
||||
This page describes the Kconfig and Devicetree file formats and how to change settings in them. See the other pages in the configuration section for a list of settings you can change. |
||||
|
||||
:::note |
||||
All configuration is currently set at compile time. After changing any settings, you must build new firmware and flash it for the changes to apply. |
||||
::: |
||||
|
||||
## Config File Locations |
||||
|
||||
ZMK will search multiple folders for the config files described below. There are three primary locations it will search: |
||||
|
||||
### User Config Folder |
||||
|
||||
When building with a `zmk-config` folder, ZMK will search the `zmk-config/config` folder for the following config files, where `<name>` is the name of the shield if using a shield, or the name of the board otherwise: |
||||
|
||||
- `<name>.conf` (Kconfig) |
||||
- `<name>.keymap` (Devicetree) |
||||
|
||||
These files hold your personal settings for the keyboard. They override any configuration set in the board or shield folders. |
||||
|
||||
When using a split keyboard, you can use a single file without the `_left` or `_right` suffix to configure both sides. For example, `corne.conf` and `corne.keymap` will apply to both `corne_left` and `corne_right`. |
||||
|
||||
### Board Folder |
||||
|
||||
ZMK will search for config files in either of: |
||||
|
||||
- [`zmk/app/boards/arm/<board>`](https://github.com/zmkfirmware/zmk/tree/main/app/boards/arm) |
||||
- `zmk-config/config/boards/arm/<board>` |
||||
|
||||
...where `<board>` is the name of the board. These files describe the hardware of the board. |
||||
|
||||
ZMK will search the board folder for the following config files: |
||||
|
||||
- `<board>_defconfig` (Kconfig) |
||||
- `<board>.dts` (Devicetree) |
||||
- `<board>.keymap` (Devictree, standalone boards only) |
||||
|
||||
For more documentation on creating and configuring a new board, see [Zephyr's board porting guide](https://docs.zephyrproject.org/latest/guides/porting/board_porting.html#write-kconfig-files). |
||||
|
||||
### Shield Folder |
||||
|
||||
When building with a shield, ZMK will search for config files in either of: |
||||
|
||||
- [`zmk/app/boards/shields/<shield>`](https://github.com/zmkfirmware/zmk/tree/main/app/boards/shields) |
||||
- `zmk-config/config/boards/shields/<shield>` |
||||
|
||||
...where `<shield>` is the name of the shield. These files describe the hardware of the shield that the board is plugged into. |
||||
|
||||
ZMK will search the shield folder for the following config files: |
||||
|
||||
- `<shield>.conf` (Kconfig) |
||||
- `<shield>.overlay` (Devicetree) |
||||
- `<shield>.keymap` (Devicetree) |
||||
|
||||
For more documentation on creating and configuring a new shield, see [Zephyr's shield documentation](https://docs.zephyrproject.org/latest/guides/porting/shields.html) and [ZMK's new keyboard shield](/docs/development/new-shield) guide. |
||||
|
||||
## Kconfig Files |
||||
|
||||
Kconfig is used to configure global settings such as the keyboard name and enabling certain hardware devices. These typically have a `.conf` file extension and are text files containing `CONFIG_XYZ=value` assignments, with one setting per line. |
||||
|
||||
Kconfig files look like this: |
||||
|
||||
``` |
||||
CONFIG_ZMK_SLEEP=y |
||||
CONFIG_EC11=y |
||||
CONFIG_EC11_TRIGGER_GLOBAL_THREAD=y |
||||
``` |
||||
|
||||
The list of available settings is determined by various files in ZMK whose names start with `Kconfig`. |
||||
|
||||
See [Zephyr's Kconfig documentation](https://docs.zephyrproject.org/latest/guides/kconfig/index.html) for more details on Kconfig files. |
||||
|
||||
### KConfig Value Types |
||||
|
||||
#### bool |
||||
|
||||
Either `y` for yes or `n` for no. |
||||
|
||||
Example: `CONFIG_FOO=y` |
||||
|
||||
#### int |
||||
|
||||
An integer. |
||||
|
||||
Example: `CONFIG_FOO=42` |
||||
|
||||
#### string |
||||
|
||||
Text surrounded by double quotes. |
||||
|
||||
Example: `CONFIG_FOO="foo"` |
||||
|
||||
## Devicetree Files |
||||
|
||||
Various Devicetree files are combined to build a tree that describes the hardware for a keyboard. They are also used to define keymaps. Common file extensions for Devicetree files are `.dts`, `.dtsi`, `.overlay`, and `.keymap`. |
||||
|
||||
Devicetree files look like this: |
||||
|
||||
```devicetree |
||||
/ { |
||||
chosen { |
||||
zmk,kscan = &kscan0; |
||||
}; |
||||
|
||||
kscan0: kscan { |
||||
compatible = "zmk,kscan-gpio-matrix"; |
||||
label = "KSCAN"; |
||||
}; |
||||
}; |
||||
``` |
||||
|
||||
Devicetree properties apply to specific nodes in the tree instead of globally. The properties that can be set for each node are determined by `.yaml` files in ZMK in the various `dts/bindings` folders. |
||||
|
||||
See [Zephyr's Devicetree guide](https://docs.zephyrproject.org/latest/guides/dts/index.html) for more details on Devicetree files. |
||||
|
||||
### Changing Devicetree Properties |
||||
|
||||
Since Devicetree properties are set for specific nodes in the tree, you will first need to find the node you want to configure. You will typically need to |
||||
search through the `.dts` file for you board, `.overlay` file for your shield, or a `.dtsi` file included in by of those files using an `#include` statement. |
||||
|
||||
A Devicetree node looks like this: |
||||
|
||||
```devicetree |
||||
kscan0: kscan { |
||||
compatible = "zmk,kscan-gpio-matrix"; |
||||
// more properties and/or nodes... |
||||
}; |
||||
``` |
||||
|
||||
The part before the colon, `kscan0`, is a label. This is optional, and it provides a shortcut to allow changing the properties of the node. The part after the colon, `kscan`, is the node's name. The values inside the curly braces are the node's properties. |
||||
|
||||
The `compatible` property indicates what type of node it is. Search this documentation for the text inside the quotes to see which properties the node |
||||
supports. You can also search ZMK for a file whose name is the value of the `compatible` property with a `.yaml` file extension. |
||||
|
||||
To set a property, see below for examples for common property types, or see [Zephyr's Devicetree documentation](https://docs.zephyrproject.org/latest/guides/dts/intro.html#writing-property-values) for more details on the syntax for properties. |
||||
|
||||
To change a property for an existing node, first find the node you want to change and find its label. Next, outside of any other node, write an ampersand (`&`) |
||||
followed by the node's label, an opening curly brace (`{`), one or more new property values, a closing curly brace (`}`), and a semicolon (`;`). |
||||
|
||||
For example, to adjust the debouncing of the `zmk,kscan-gpio-matrix` node shown above, you could add this to your keymap: |
||||
|
||||
```devicetree |
||||
&kscan0 { |
||||
debounce-period = <7>; |
||||
}; |
||||
``` |
||||
|
||||
### Devicetree Property Types |
||||
|
||||
These are some of the property types you will see most often when working with ZMK. [Zephyr's Devicetree bindings documentation](https://docs.zephyrproject.org/latest/guides/dts/bindings.html) provides more detailed information and a full list of types. |
||||
|
||||
#### bool |
||||
|
||||
True or false. To set the property to true, list it with no value. To set it to false, do not list it. |
||||
|
||||
Example: `property;` |
||||
|
||||
If a property has already been set to true and you need to override it to false, use the following command to delete the existing property: |
||||
|
||||
```devicetree |
||||
/delete-property/ the-property-name; |
||||
``` |
||||
|
||||
#### int |
||||
|
||||
A single integer surrounded by angle brackets. Also supports mathematical expressions. |
||||
|
||||
Example: `property = <42>;` |
||||
|
||||
#### string |
||||
|
||||
Text surrounded by double quotes. |
||||
|
||||
Example: `property = "foo";` |
||||
|
||||
#### array |
||||
|
||||
A list of integers surrounded by angle brackets and separated with spaces. Mathematical expressions can be used but must be surrounded by parenthesis. |
||||
|
||||
Example: `property = <1 2 3 4>;` |
||||
|
||||
Values can also be split into multiple blocks, e.g. `property = <1 2>, <3 4>;` |
||||
|
||||
#### phandle |
||||
|
||||
A single node reference surrounded by angle brackets. |
||||
|
||||
Example: `property = <&label>` |
||||
|
||||
#### phandles |
||||
|
||||
A list of node references surrounded by angle brackets. |
||||
|
||||
Example: `property = <&label1 &label2 &label3>` |
||||
|
||||
#### phandle array |
||||
|
||||
A list of node references and possibly numbers to associate with the node. Mathematical expressions can be used but must be surrounded by parenthesis. |
||||
|
||||
Example: `property = <&none &mo 1>;` |
||||
|
||||
Values can also be split into multiple blocks, e.g. `property = <&none>, <&mo 1>;` |
||||
|
||||
See the documentation for "phandle-array" in [Zephyr's Devicetree bindings documentation](https://docs.zephyrproject.org/latest/guides/dts/bindings.html) |
||||
for more details on how parameters are associated with nodes. |
||||
|
||||
#### GPIO array |
||||
|
||||
This is just a phandle array. The documentation lists this as a different type to make it clear which properties expect an array of GPIOs. |
||||
|
||||
Each item in the array should be a label for a GPIO node (the names of which differ between hardware platforms) followed by an index and configuration flags. See [Zephyr's GPIO documentation](https://docs.zephyrproject.org/latest/reference/peripherals/gpio.html) for a full list of flags. |
||||
|
||||
Example: |
||||
|
||||
```devicetree |
||||
some-gpios = |
||||

||||
### Example Configuration |
||||
|
||||
For example, consider a macropad with a 3x3 matrix and two direct GPIO keys: |
||||
|
||||
<div style={{columns: 2, marginBottom: '1em'}}> |
||||
<div style={{breakInside: 'avoid'}}> |
||||
Matrix: |
||||
|
||||
<table> |
||||
<thead> |
||||
<tr><th></th><th>Col 0</th><th>Col 1</th><th>Col 2</th></tr> |
||||
</thead> |
||||
<tbody> |
||||
<tr><th>Row 0</th><td>A0</td><td>A1</td><td>A2</td></tr> |
||||
<tr><th>Row 1</th><td>A3</td><td>A4</td><td>A5</td></tr> |
||||
<tr><th>Row 2</th><td>A6</td><td>A7</td><td>A8</td></tr> |
||||
</tbody> |
||||
</table> |
||||
</div> |
||||
|
||||
<div style={{breakInside: 'avoid'}}> |
||||
Direct GPIO: |
||||
|
||||
<table> |
||||
<thead> |
||||
<tr><th></th><th>Col 0</th><th>Col 1</th></tr> |
||||
</thead> |
||||
<tbody> |
||||
<tr><th>Row 0</th><td>B0</td><td>B1</td></tr> |
||||
</tbody> |
||||
</table> |
||||
</div> |
||||
</div> |
||||
|
||||
To combine them, we need to create a composite matrix with enough rows and columns to fit both sets of keys without overlapping, then set row and/or columns offsets to shift them so they do not overlap. |
||||
|
||||
One possible way to do this is a 3x4 matrix where the direct GPIO keys are shifted to below the matrix keys... |
||||
|
||||
<table> |
||||
<thead> |
||||
<tr><th></th><th>Col 0</th><th>Col 1</th><th>Col 2</th></tr> |
||||
</thead> |
||||
<tbody> |
||||
<tr><th>Row 0</th><td>A0</td><td>A1</td><td>A2</td></tr> |
||||
<tr><th>Row 1</th><td>A3</td><td>A4</td><td>A5</td></tr> |
||||
<tr><th>Row 2</th><td>A6</td><td>A7</td><td>A8</td></tr> |
||||
<tr><th>Row 3</th><td>B0</td><td>B1</td><td>(none)</td></tr> |
||||
</tbody> |
||||
</table> |
||||
|
||||
...which can be configured with the following Devicetree code: |
||||
|
||||
```devicetree |
||||
/ { |
||||
chosen { |
||||
zmk,kscan = &kscan0; |
||||
}; |
||||
|
||||
kscan0: kscan_composite { |
||||
compatible = "zmk,kscan-composite"; |
||||
label = "KSCAN0"; |
||||
rows = <3>; |
||||
columns = <4>; |
||||
|
||||
// Include the matrix driver |
||||
matrix { |
||||
kscan = <&kscan1>; |
||||
}; |
||||
|
||||
// Include the direct GPIO driver... |
||||
direct { |
||||
kscan = <&kscan2>; |
||||
row-offset = <3>; // ..and shift it to not overlap |
||||
}; |
||||
}; |
||||
|
||||
kscan1: kscan_matrix { |
||||
compatible = "zmk,kscan-gpio-matrix"; |
||||
// define 3x3 matrix here... |
||||
}; |
||||
|
||||
kscan2: kscan_direct { |
||||
compatible = "zmk,kscan-gpio-direct"; |
||||
// define 2 direct GPIOs here... |
||||
}; |
||||
} |
||||
``` |
||||
|
||||
## Mock Driver |
||||
|
||||
Mock keyboard scan driver that simulates key events. |
||||
|
||||
### Kconfig |
||||
|
||||

||||
|
||||
### Devicetree |
||||
|
||||
Applies to: `compatible = "zmk,kscan-mock"` |
||||
|
||||
Definition file: [zmk/app/dts/bindings/zmk,kscan-mock.yaml](https://github.com/zmkfirmware/zmk/blob/main/app/dts/bindings/zmk%2Ckscan-mock.yaml) |
||||
|
||||
| Property | Type | Description | Default | |
||||
| -------------- | ------ | --------------------------------------------- | ------- | |
||||
| `label` | string | Unique label for the node | | |
||||
| `event-period` | int | Milliseconds between each generated event | | |
||||
| `events` | array | List of key events to simulate | | |
||||
| `rows` | int | The number rows of in the composite matrix | | |
||||
| `cols` | int | The number columns of in the composite matrix | | |
||||
| `exit-after` | bool | Exit the program after running all events | false | |
||||
|
||||
The `events` array should be defined using the macros from [dt-bindings/zmk/kscan_mock.h](https://github.com/zmkfirmware/zmk/blob/main/app/include/dt-bindings/zmk/kscan_mock.h). |
||||
|
||||
## Matrix Transform |
||||
|
||||
Defines a mapping from keymap logical positions to physical matrix positions. |
||||
|
||||
Transforms should be used any time the physical layout of a keyboard's keys does not match the layout of its electrical matrix and/or when not all positions in the matrix are used. This applies to most non-ortholinear boards. |
||||
|
||||
Transforms can also be used for keyboards with multiple layouts. You can define multiple matrix transform nodes, one for each layout, and users can select which one they want from the `/chosen` node in their keymaps. |
||||
|
||||
See the [new shield guide](/docs/development/new-shield/#optional-matrix-transform) for more documentation on how to define a matrix transform. |
||||
|
||||
### Devicetree |
||||
|
||||
Applies to: `compatible = "zmk,matrix-transform"` |
||||
|
||||
Definition file: [zmk/app/dts/bindings/zmk,matrix-transform.yaml](https://github.com/zmkfirmware/zmk/blob/main/app/dts/bindings/zmk%2Cmatrix-transform.yaml) |
||||
|
||||
| Property | Type | Description | Default | |
||||
| ------------ | ----- | --------------------------------------------------------------------- | ------- | |
||||
| `rows` | int | Number of rows in the transformed matrix | | |
||||
| `columns` | int | Number of columns in the transformed matrix | | |
||||
| `row-offset` | int | Adds an offset to all rows before looking them up in the transform | 0 | |
||||
| `col-offset` | int | Adds an offset to all columns before looking them up in the transform | 0 | |
||||
| `map` | array | A list of position transforms | | |
||||
|
||||
The `map` array should be defined using the `RC()` macro from [dt-bindings/zmk/matrix_transform.h](https://github.com/zmkfirmware/zmk/blob/main/app/include/dt-bindings/zmk/matrix_transform.h). It should have one item per logical position in the keymap. Each item should list the physical row and column that should trigger the key in that position. |
||||
|
||||
### Example Configuration |
||||
|
||||
Consider a keyboard with a [duplex matrix](https://wiki.ai03.com/books/pcb-design/page/matrices-and-duplex-matrix), where the matrix has twice as many rows and half as many columns as the keyboard has keys. A matrix transform can be used to correct for this so that keymaps can match the layout of the keys, not the layout of the matrix. |
||||
|
||||
```devicetree |
||||
/ { |
||||
chosen { |
||||
zmk,kscan = &kscan0; |
||||
zmk,matrix_transform = &default_transform; |
||||
}; |
||||
|
||||
kscan0: kscan { |

default_transform: matrix_transform { |
||||
compatible = "zmk,matrix-transform"; |
||||
rows = <6>; |
||||
columns = <16>; |
||||
// ESC F1 F2 F3 ... |

## Idle/Sleep |
||||
|
||||
Configuration for entering low power modes when the keyboard is idle. |
||||
|
||||
In the idle state, peripherals such as displays and lighting are disabled, but the keyboard remains connected to Bluetooth so it can immediately respond when you press a key. |
||||
|
||||
In the deep sleep state, the keyboard additionally disconnects from Bluetooth. This state uses very little power, but it may take a few seconds to reconnect after waking. |

||||
|
||||
See the [RGB Underglow feature page](/docs/features/underglow) for more details, including instructions for adding underglow support to a board. |
||||
|
||||
See [Configuration Overview](/docs/config/index) for instructions on how to change these settings. |
||||
|
||||
## Kconfig |
||||
|
||||
RGB underglow depends on [Zephyr's LED strip driver](https://github.com/zephyrproject-rtos/zephyr/tree/master/drivers/led_strip), which provides additional Kconfig options. |
||||
|
||||
Definition file: [zmk/app/Kconfig](https://github.com/zmkfirmware/zmk/blob/main/app/Kconfig) |
||||
|
||||
| Config | Type | Description | Default | |
||||
| ------------------------------------ | ---- | ----------------------------------------------------- | ------- | |
||||

## Devicetree |
||||
|
||||
ZMK does not have any Devicetree properties of its own. See the Devicetree bindings for [Zephyr's LED strip driver](https://github.com/zephyrproject-rtos/zephyr/tree/master/dts/bindings/led_strip). |
||||
|
||||
See the [RGB underglow feature page](/docs/features/underglow) for examples of the properties that must be set to enable underglow. |
