# The `config.h` file
|
||||
|
||||
This is a c header file that is one of the first things included, and will persist over the whole project (if included). Lots of variables can be set here and accessed elsewhere (namely keymaps). This file can exist at a couple different levels:
|
||||
|
||||
## Keyboard
|
||||
# Configuring QMK
|
||||
|
||||
```c
|
||||
#ifndef CONFIG_H
|
||||
#define CONFIG_H
|
||||
QMK is nearly infinitely configurable. Wherever possible we err on the side of allowing users to customize their keyboard, even at the expense of code size. That level of flexibility makes for a daunting configuration experience, however.
|
||||
|
||||
#include "config_common.h"
|
||||
There are two main types of configuration files in QMK- `config.h` and `rules.mk`. These files exist at various levels in QMK and all files of the same type are combined to build the final configuration. The levels, from lowest priority to highest priority, are:
|
||||
|
||||
// config options
|
||||
* QMK Default
|
||||
* Keyboard
|
||||
* Folders (Up to 5 levels deep)
|
||||
* Keymap
|
||||
|
||||
#endif
|
||||
```
|
||||
## QMK Default
|
||||
|
||||
This file contains config options that should apply to the whole keyboard, and won't change in revisions, or most keymaps. The revision block here only applies to keyboards with revisions.
|
||||
Every available setting in QMK has a default. If that setting is not set at the Keyboard, Folder, or Keymap level this is the setting that will be used.
|
||||
|
||||
## Revisions
|
||||
|
||||
```c
|
||||
#ifndef <revision>_CONFIG_H
|
||||
#define <revision>_CONFIG_H
|
||||
|
||||
#include "config_common.h"
|
||||
## Keyboard
|
||||
|
||||
// config options
|
||||
This level contains config options that should apply to the whole keyboard. Some settings won't change in revisions, or most keymaps. Other settings are merely defaults for this keyboard and can be overridden by folders and/or keymaps.
|
||||
|
||||
#endif
|
||||
```
|
||||
## Folders
|
||||
|
||||
For keyboards that have revisions, this file contains config options that should apply to only that revisions, and won't change in most keymaps.
|
||||
Some keyboards have folders and sub-folders to allow for different hardware configurations. Most keyboards only go 1 folder deep, but QMK supports structures up to 5 folders deep. Each folder can have its own `config.h` and `rules.mk` files that are incorporated into the final configuration.
|
||||
|
||||
## Keymap
|
||||
|
||||
```c
|
||||
#ifndef CONFIG_USER_H
|
||||
#define CONFIG_USER_H
|
||||
|
||||
#include "config_common.h"
|
||||
|
||||
// config options
|
||||
|
||||
#endif
|
||||
```
|
||||
|
||||
This file contains all of the options for that particular keymap. If you wish to override a previous declaration, you can use `#undef <variable>` to undefine it, where you can then redefine it without an error.
|
||||
|
||||
# Config Options
|
||||
|
||||
```c
|
||||
#define VENDOR_ID 0x1234 // defines your VID, and for most DIY projects, can be whatever you want

# The `rules.mk` File
|
||||
|
||||
This is a [make](https://www.gnu.org/software/make/manual/make.html) file that is included by the top-level `Makefile`. It is used to set some information about the MCU that we will be compiling for as well as enabling and disabling certain features.
|
||||
|
||||
## `rules.mk` options
|
||||
|
||||
### Build Options
|
||||
|
||||
* `DEFAULT_FOLDER`
|
||||
* Used to specify a default folder when a keyboard has more than one sub-folder.
|
||||
* `SRC`
|
||||
* Used to add files to the compilation/linking list.
|
||||
* `LAYOUTS`
|
||||
* A list of [layouts](feature_layouts.md) this keyboard supports.
|
||||
|
||||
### AVR MCU Options
|
||||
* `MCU = atmega32u4`
|
||||
* `F_CPU = 16000000`

||||
* `ARCH = AVR8`
|
||||
* `F_USB = $(F_CPU)`

||||
* `OPT_DEFS += -DINTERRUPT_CONTROL_ENDPOINT`
|
||||
* `OPT_DEFS += -DBOOTLOADER_SIZE=4096`
|
||||
|
||||
### Feature Options
|
||||
|
||||
Use these to enable or disable building certain features. The more you have enabled the bigger your firmware will be, and you run the risk of building a firmware too large for your MCU.

# QMK Features
|
||||
|
||||
|
||||
## Space Cadet Shift: The future, built in
|
||||
|
||||
Steve Losh [described](http://stevelosh.com/blog/2012/10/a-modern-space-cadet/) the Space Cadet Shift quite well. Essentially, you hit the left Shift on its own, and you get an opening parenthesis; hit the right Shift on its own, and you get the closing one. When hit with other keys, the Shift key keeps working as it always does. Yes, it's as cool as it sounds. Head on over to the [Space Cadet Shift](space_cadet_shift.md) page to read about it.
|
||||
|
||||
## The Leader key: A new kind of modifier
|
||||
|
||||
Most modifiers have to be held or toggled. But what if you had a key that indicated the start of a sequence? You could press that key and then rapidly press 1-3 more keys to trigger a macro, or enter a special layer, or anything else you might want to do. To learn more about it check out the [Leader Key](feature_leader_key.md) page.
|
||||
|
||||
## Tap Dance: A single key can do 3, 5, or 100 different things
|
||||
|
||||
Hit the semicolon key once, send a semicolon. Hit it twice, rapidly -- send a colon. Hit it three times, and your keyboard's LEDs do a wild dance. That's just one example of what Tap Dance can do. Read more about it on the [Tap Dance](tap_dance.md) page.
|
||||
|
||||
## Temporarily setting the default layer
|
||||
|
||||
`DF(layer)` - sets default layer to _layer_. The default layer is the one at the "bottom" of the layer stack - the ultimate fallback layer. This currently does not persist over power loss. When you plug the keyboard back in, layer 0 will always be the default. It is theoretically possible to work around that, but that's not what `DF` does.
|
||||
|
||||
## Macro shortcuts: Send a whole string when pressing just one key
|
||||
|
||||
How would you like a single keypress to send a whole word, sentence, paragraph, or even document? Head on over to the [Macros](macros.md) page to read up on all aspects of Simple and Dynamic Macros.
|
||||
|
||||
## Additional keycode aliases for software-implemented layouts \(Colemak, Dvorak, etc\)
|
||||
|
||||
Everything is assuming you're in Qwerty \(in software\) by default, but there is built-in support for using a Colemak or Dvorak layout by including this at the top of your keymap:
|
||||
|
||||
```
|
||||
#include <keymap_colemak.h>
|
||||
```
|
||||
|
||||
If you use Dvorak, use `keymap_dvorak.h` instead of `keymap_colemak.h` for this line. After including this line, you will get access to:
|
||||
|
||||
* `CM_*` for all of the Colemak-equivalent characters
|
||||
* `DV_*` for all of the Dvorak-equivalent characters
|
||||
|
||||
These implementations assume you're using Colemak or Dvorak on your OS, not on your keyboard - this is referred to as a software-implemented layout. If your computer is in Qwerty and your keymap is in Colemak or Dvorak, this is referred to as a firmware-implemented layout, and you won't need these features.
|
||||
|
||||
To give an example, if you're using software-implemented Colemak, and want to get an `F`, you would use `CM_F`. Using `KC_F` under these same circumstances would result in `T`.
|
||||
|
||||
## Backlight Breathing
|
||||
|
||||
In order to enable backlight breathing, the following line must be added to your config.h file.
|
||||
|
||||
```
|
||||
#define BACKLIGHT_BREATHING
|
||||
```
|
||||
|
||||
The following function calls are used to control the breathing effect.
|
||||
|
||||
* `breathing_enable()` - Enable the free-running breathing effect.
|
||||
* `breathing_disable()` - Disable the free-running breathing effect immediately.
|
||||
* `breathing_self_disable()` - Disable the free-running breathing effect after the current effect ends.
|
||||
* `breathing_toggle()` - Toggle the free-running breathing effect.
|
||||
* `breathing_defaults()` - Reset the speed and brightness settings of the breathing effect.
|
||||
|
||||
The following function calls are used to control the maximum brightness of the breathing effect.
|
||||
|
||||
* `breathing_intensity_set(value)` - Set the brightness of the breathing effect when it is at its max value.
|
||||
* `breathing_intensity_default()` - Reset the brightness of the breathing effect to the default value based on the current backlight intensity.
|
||||
|
||||
The following function calls are used to control the cycling speed of the breathing effect.
|
||||
|
||||
* `breathing_speed_set(value)` - Set the speed of the breathing effect - how fast it cycles.
|
||||
* `breathing_speed_inc(value)` - Increase the speed of the breathing effect by a fixed value.
|
||||
* `breathing_speed_dec(value)` - Decrease the speed of the breathing effect by a fixed value.
|
||||
* `breathing_speed_default()` - Reset the speed of the breathing effect to the default value.
|
||||
|
||||
The following example shows how to enable the backlight breathing effect when the FUNCTION layer macro button is pressed:
|
||||
|
||||
```
|
||||
case MACRO_FUNCTION:
|
||||
if (record->event.pressed)
|
||||
{
|
||||
breathing_speed_set(3);
|
||||
breathing_enable();
|
||||
layer_on(LAYER_FUNCTION);
|
||||
}
|
||||
else
|
||||
{
|
||||
breathing_speed_set(1);
|
||||
breathing_self_disable();
|
||||
layer_off(LAYER_FUNCTION);
|
||||
}
|
||||
break;
|
||||
```
|
||||
|
||||
The following example shows how to pulse the backlight on-off-on when the RAISED layer macro button is pressed:
|
||||
|
||||
```
|
||||
case MACRO_RAISED:
|
||||
if (record->event.pressed)
|
||||
{
|
||||
layer_on(LAYER_RAISED);
|
||||
breathing_speed_set(2);
|
||||
breathing_pulse();
|
||||
update_tri_layer(LAYER_LOWER, LAYER_RAISED, LAYER_ADJUST);
|
||||
}
|
||||
else
|
||||
{
|
||||
layer_off(LAYER_RAISED);
|
||||
update_tri_layer(LAYER_LOWER, LAYER_RAISED, LAYER_ADJUST);
|
||||
}
|
||||
break;
|
||||
```

# Keyboards With AVR Processors
|
||||
|
||||
This page describes the support for for AVR processors in QMK. AVR processors include the atmega32u4, atmega32u2, at90usb1286, and other processors from Atmel Corporation. AVR processors are 8-bit MCU's that are designed to be easy to work with. The most common AVR processors in keyboards have on-board USB and plenty of GPIO for supporting large keyboard matrices. They are the most popular MCU for use in keyboards today.
|
||||
|
||||
If you have not yet you should read the [Keyboard Guidelines](hardware_keyboard_guidelines.md) to get a sense of how keyboards fit into QMK.
|
||||
|
||||
## Adding Your AVR Keyboard to QMK
|
||||
|
||||
QMK has a number of features to simplify working with AVR keyboards. For most keyboards you don't have to write a single line of code. To get started run the `util/new_project.sh` script:
|
||||
|
||||
```
|
||||
$ util/new_project.sh my_awesome_keyboard
|
||||
######################################################
|
||||
# /keyboards/my_awesome_keyboard project created. To start
|
||||
# working on things, cd into keyboards/my_awesome_keyboard
|
||||
######################################################
|
||||
```
|
||||
|
||||
This will create all the files needed to support your new keyboard, and populate the settings with default values. Now you just need to customize it for your keyboard.
|
||||
|
||||
## `readme.md`
|
||||
|
||||
This is where you'll describe your keyboard. Please follow the [Keyboard Readme Template](documentation_templates.md#keyboard-readmemd-template) when writing your `readme.md`. You're encouraged to place an image at the top of your `readme.md`, please use an external service such as [Imgur](http://imgur.com) to host the images.
|
||||
|
||||
## `<keyboard>.c`
|
||||
|
||||
This is where all the custom logic for your keyboard goes. Many keyboards do not need to put anything at all in here. You can learn more about writing custom logic in [Custom Quantum Functions](custom_quantum_functions.md).
|
||||
|
||||
## `<keyboard>.h`
|
||||
|
||||
This is the file you define your [Layout Macro(s)](feature_layouts.md) in. At minumum you should have a `#define LAYOUT` for your keyboard that looks something like this:
|
||||
|
||||
```
|
||||
#define LAYOUT( \
|
||||
k00, k01, k02, \
|
||||
k10, k11 \
|
||||
) { \
|
||||
{ k00, k01, k02 }, \
|
||||
{ k10, KC_NO, k11 }, \
|
||||
}
|
||||
```
|
||||
|
||||
The first half of the `LAYOUT` pre-processor macro defines the physical arrangement of keys. The second half of the macro defines the matrix the switches are connected to. This allows you to have a physical arrangement of keys that differs from the wiring matrix.
|
||||
|
||||
Each of the `k__` variables needs to be unique, and typically they follow the format `k<row><col>`.
|
||||
|
||||
The physical matrix (the second half) must have a number of rows equalling `MATRIX_ROWS`, and each row must have exactly `MATRIX_COLS` elements in it. If you do not have this many physical keys you can use `KC_NO` to fill in the blank spots.
|
||||
|
||||
## `config.h`
|
||||
|
||||
The `config.h` file is where you configure the hardware and feature set for your keyboard. There are a lot of options that can be placed in that file, too many to list there. For a complete overview of available options see the [Config Options](config_options.md) page.
|
||||
|
||||
### Hardware Configuration
|
||||
|
||||
|
||||
At the top of the `config.h` you'll find USB related settings. These control how your keyboard appears to the Operating System. If you don't have a good reason to change you should leave the `VENDOR_ID` as `0xFEED`. For the `PRODUCT_ID` you should pick a number that is not yet in use.
|
||||
|
||||
Do change the `MANUFACTURER`, `PRODUCT`, and `DESCRIPTION` lines to accurately reflect your keyboard.
|
||||
|
||||
```
|
||||
#define VENDOR_ID 0xFEED
|
||||
#define PRODUCT_ID 0x6060
|
||||
#define DEVICE_VER 0x0001
|
||||
#define MANUFACTURER You
|
||||
#define PRODUCT my_awesome_keyboard
|
||||
#define DESCRIPTION A custom keyboard
|
||||
```
|
||||
|
||||
{% hint style='info' %}
|
||||
Note: On Windows and macOS the `MANUFACTURER`, `PRODUCT`, and `DESCRIPTION` fields will be displayed in the list of USB devices. On Linux these values will not be visible in `lsusb`, since Linux takes that information from the list published by the USB-IF.
|
||||
{% endhint %}
|
||||
|
||||
### Keyboard Matrix Configuration
|
||||
|
||||
The next section of the `config.h` file deals with your keyboard's matrix. The first thing you should set is the matrix's size. This is usually, but not always, the same number of rows and columns as the physical key arrangement.
|
||||
|
||||
```
|
||||
#define MATRIX_ROWS 2
|
||||
#define MATRIX_COLS 3
|
||||
```
|
||||
|
||||
Once you've defined the size of your matrix you need to define which pins on your MCU are connected to rows and columns. To do so simply specify the names of those pins:
|
||||
|
||||
```
|
||||
#define MATRIX_ROW_PINS { D0, D5 }
|
||||
#define MATRIX_COL_PINS { F1, F0, B0 }
|
||||
#define UNUSED_PINS
|
||||
```
|
||||
|
||||
The number of `MATRIX_ROW_PINS` entries must be the same as the number you assigned to `MATRIX_ROWS`, and likewise for `MATRIX_COL_PINS` and `MATRIX_COLS`. You do not have to specify `UNUSED_PINS`, but you can if you want to document what pins are open.
|
||||
|
||||
Finally, you can specify the direction your diodes point. This can be `COL2ROW`, `ROW2COL`, or `CUSTOM_MATRIX`.
|
||||
|
||||
```
|
||||
#define DIODE_DIRECTION COL2ROW
|
||||
```
|
||||
|
||||
### Backlight Configuration
|
||||
|
||||
By default QMK supports backlighting on pins `B5`, `B6`, and `B7`. If you are using one of those you can simply enable it here. For more details see the [Backlight Documentation](feature_backlight.md).
|
||||
|
||||
```
|
||||
#define BACKLIGHT_PIN B7
|
||||
#define BACKLIGHT_BREATHING
|
||||
#define BACKLIGHT_LEVELS 3
|
||||
```
|
||||
|
||||
{% hint style='info' %}
|
||||
You can use backlighting on any pin you like, but you will have to do more work to support that. See the [Backlight Documentation](feature_backlight.md) for more details.
|
||||
{% endhint %}
|
||||
|
||||
### Other Configuration Options
|
||||
|
||||
There are a lot of features that can be configured or tuned in `config.h`. You should see the [Config Options](config_options.md) page for more details.
|
||||
|
||||
## `rules.mk`
|
||||
|
||||
You use the `rules.mk` file to tell QMK what files to build and what features to enable. If you are building around an atmega32u4 you can largely leave these defaults alone. If you are using another MCU you may have to tweak some parameters.
|
||||
|
||||
### MCU Options
|
||||
|
||||
These options tell the build system what CPU to build for. Be very careful if you change any of these settings, you can render your keyboard inoperable.
|
||||
|
||||
```
|
||||
MCU = atmega32u4
|
||||
F_CPU = 16000000
|
||||
ARCH = AVR8
|
||||
F_USB = $(F_CPU)
|
||||
OPT_DEFS += -DINTERRUPT_CONTROL_ENDPOINT
|
||||
```
|
||||
|
||||
### Bootloader Size
|
||||
|
||||
The bootloader is a special section of your MCU that allows you to upgrade the code stored on the MCU. Think of it like a Rescue Partition for your keyboard. If you are using a teensy 2.0, or a device like the Ergodox EZ that uses the teensy bootloader you should set this to `512`. Most other bootloaders should be set to `4096`, but `1024` and `2048` are other possible values you may encounter.
|
||||
|
||||
#### Teensy 2.0 Bootloader Example
|
||||
|
||||
```
|
||||
OPT_DEFS += -DBOOTLOADER_SIZE=512
|
||||
```
|
||||
|
||||
#### Teensy 2.0++ Bootloader Example
|
||||
|
||||
```
|
||||
OPT_DEFS += -DBOOTLOADER_SIZE=1024
|
||||
```
|
||||
|
||||
#### Atmel DFU Loader Example
|
||||
|
||||
```
|
||||
OPT_DEFS += -DBOOTLOADER_SIZE=4096
|
||||
```
|
||||
|
||||
### Build Options
|
||||
|
||||
There are a number of features that can be turned on or off in `rules.mk`. See the [Config Options](config_options.md#feature-options) page for a detailed list and description.

# QMK Hardware Drivers
|
||||
|
||||
QMK is used on a lot of different hardware. While support for the most common MCU's and matrix configurations is built-in there are a number of drivers that can be added to a keyboard to support additional hardware. Examples include mice and other pointing devices, i/o expanders for split keyboards, bluetooth modules, and LCD, OLED, and TFT screens.

|
||||
|

|
||||
|
||||
## Image/Hardware files
|
||||
|
||||
In an effort to keep the repo size down, we're no longer accepting images of any format in the repo, with few exceptions. Hosting them elsewhere (imgur) and linking them in the readme.md is the preferred method.

Any sort of hardware file (plate, case, pcb) can't be stored in qmk_firmware, but we have the [qmk.fm repo](https://github.com/qmk/qmk.fm) where such files (as well as in-depth info) can be store, and viewed on [qmk.fm](http://qmk.fm). Downloadable files are stored in `/<keyboard>/` (name follows the same format as above) which are served at `http://qmk.fm/<keyboard>/`, and pages are generated from `/_pages/<keyboard>/` which are served at the same location (.md files are generated into .html files through Jekyll). Check out the `lets_split` directory for an example.

We're happy to accept any project that uses QMK, including prototypes and handwired ones, but we have a separate `/keyboards/handwired/` folder for them, so the main `/keyboards/` folder doesn't get overcrowded. If a prototype project becomes a production project at some point in the future, we'd be happy to move it to the main `/keyboards/` folder!

|
||||
|
||||
## Warnings as errors
|
||||
|
||||
When developing your keyboard, keep in mind that all warnings will be treated as errors - these small warnings can build-up and cause larger errors down the road (and keeping them is generally a bad practice).
|
||||
|
||||
## Licenses
|
||||
## Copyright Blurb
|
||||
|
||||
If you're adapting your keyboard's setup from another project, but not using the same code, but sure to update the copyright header at the top of the files to show your name, in this format:
|
||||
|
||||
Copyright 2017 Your Name <your@email.com>
|
||||
|
||||
|
||||
If you are modifying someone else's code and have made only trivial changes you should leave their name in the copyright statement. If you have done significant work on the file you should add your name to theirs, like so:
|
||||
|
||||
Copyright 2017 Their Name <original_author@example.com> Your Name <you@example.com>
|
||||
|
||||
The year should be the first year the file is created. If work was done to that file in later years you can reflect that by appending the second year to the first, like so:
|
||||
|
||||
Copyright 2015-2017 Your Name <you@example.com>

# Porting your keyboard to QMK
|
||||
|
||||
This page describes the technical details of porting an existing keyboard to QMK. If you're looking to add your keyboard to QMK, please [look through these guidelines](adding_a_keyboard_to_qmk.md)!
|
||||
|
||||
If your keyboard is running an Atmega chip (atmega32u4 and others), it's pretty easy to get things setup for compiling your own firmware to flash onto your board. There is a `/util/new_project.sh <keyboard>` script to help get you started - you can simply pass your keyboard's name into the script, and all of the necessary files will be created. The components of each are described below.
|
||||
|
||||
## `/keyboards/<keyboard>/config.h`
|
||||
|
||||
The `USB Device descriptor parameter` block contains parameters are used to uniquely identify your keyboard, but they don't really matter to the machine.
|
||||
|
||||
Your `MATRIX_ROWS` and `MATRIX_COLS` are the numbers of rows and cols in your keyboard matrix - this may be different than the number of actual rows and columns on your keyboard. There are some tricks you can pull to increase the number of keys in a given matrix, but most keyboards are pretty straight-forward.
|
||||
|
||||
The `MATRIX_ROW_PINS` and `MATRIX_COL_PINS` are the pins your MCU uses on each row/column. Your schematic (if you have one) will have this information on it, and the values will vary depending on your setup. This is one of the most important things to double-check in getting your keyboard setup correctly.
|
||||
|
||||
For the `DIODE_DIRECTION`, most hand-wiring guides will instruct you to wire the diodes in the `COL2ROW` position, but it's possible that they are in the other - people coming from EasyAVR often use `ROW2COL`. Nothing will function if this is incorrect.
|
||||
|
||||
`BACKLIGHT_PIN` is the pin that your PWM-controlled backlight (if one exists) is hooked-up to. Currently only B5, B6, and B7 are supported.
|
||||
|
||||
`BACKLIGHT_BREATHING` is a fancier backlight feature that adds breathing/pulsing/fading effects to the backlight. It uses the same timer as the normal backlight. These breathing effects must be called by code in your keymap.
|
||||
|
||||
`BACKLIGHT_LEVELS` is how many levels exist for your backlight - max is 15, and they are computed automatically from this number.
|
||||
|
||||
## `/keyboards/<keyboard>/rules.mk`
|
||||
|
||||
The values at the top likely won't need to be changed, since most boards use the `atmega32u4` chip. The `BOOTLOADER_SIZE` will need to be adjusted based on your MCU type. It's defaulted to the Teensy, since that's the most common controller. Below is quoted from the `Makefile`.
|
||||
|
||||
```
|
||||
# Boot Section Size in *bytes*
|
||||
# Teensy halfKay 512
|
||||
# Teensy++ halfKay 1024
|
||||
# Atmel DFU loader 4096
|
||||
# LUFA bootloader 4096
|
||||
# USBaspLoader 2048
|
||||
OPT_DEFS += -DBOOTLOADER_SIZE=512
|
||||
```
|
||||
|
||||
At the bottom of the file, you'll find lots of features to turn on and off - all of these options should be set with `?=` to allow for the keymap overrides. `?=` only assigns if the variable was previously undefined. For the full documenation of these features, see the [Makefile options](getting_started_make_guide.md#makefile-options).
|
||||
|
||||
## `/keyboards/<keyboard>/readme.md`
|
||||
|
||||
This is where you'll describe your keyboard - please write as much as you can about it! Talking about default functionality/features is useful here. Feel free to link to external pages/sites if necessary. Images can be included here as well, as long as they're hosted elsewhere (imgur).
|
||||
|
||||
## `/keyboards/<keyboard>/<keyboard>.c`
|
||||
|
||||
This is where all of the custom logic for your keyboard goes - you may not need to put anything in this file, since a lot of things are configured automatically. All of the `*_kb()` functions are defined here. If you modify them, remember to keep the calls to `*_user()`, or things in the keymaps might not work. You can read more about the functions [here](custom_quantum_functions.md).
|
||||
|
||||
## `/keyboards/<keyboard>/<keyboard>.h`
|
||||

Here is where you can (optionally) define your `KEYMAP` function to remap your matrix into a more readable format. With ortholinear boards, this isn't always necessary, but it can help to accomodate the dead spots on your matrix, where there are keys that take up more than one space (2u, staggering, 6.25u, etc). The example shows the difference between the physical keys, and the matrix design:
|
||||
|
||||
```
|
||||
#define KEYMAP( \
|
||||
k00, k01, k02, \
|
||||
k10, k11 \
|
||||
) \
|
||||
{ \
|
||||
{ k00, k01, k02 }, \
|
||||
{ k10, KC_NO, k11 }, \
|
||||
}
|
||||
```
|
||||
|
||||
Each of the `kxx` variables needs to be unique, and usually follows the format `k<row><col>`. You can place `KC_NO` where your dead keys are in your matrix.
