This page attempts to explain the basic information you need to know to work with the QMK project. It assumes that you are familiar with navigating a Unix shell, but does not assume you are familiar with C or with compiling using make.
QMK is a fork of Jun Wako's tmk_keyboard project. The original TMK code, with modifications, can be found in the tmk
folder. The QMK additions to the project may be found in the quantum
folder. Keyboard projects may be found in the handwired
and keyboard
folders.
Within the folder keyboards
and its subfolder handwired
is a directory for each keyboard project, for example qmk_firmware/keyboards/clueboard
. Within it you'll find the following structure:
keymaps/
: Different keymaps that can be builtrules.mk
: The file that sets the default "make" options. Do not edit this file directly, instead use a keymap specificMakefile
config.h
: The file that sets the default compile time options. Do not edit this file directly, instead use a keymap specificconfig.h
.
In every keymap folder, the following files may be found. Only keymap.c
is required, and if the rest of the files are not found the default options will be chosen.
config.h
: the options to configure your keymapkeymap.c
: all of your keymap code, requiredrules.mk
: the features of QMK that are enabledreadme.md
: a description of your keymap, how others might use it, and explanations of features. Please upload images to a service like imgur.
There are 2 config.h
locations:
- keyboard (
/keyboards/<keyboard>/config.h
) - keymap (
/keyboards/<keyboard>/keymaps/<keymap>/config.h
)
If the keymap config.h
exists, that file is included by the build system and the keyboard config.h
is not included. If you wish to override settings in your keymap's config.h
you will need to include some glue code:
#ifndef CONFIG_USER_H
#define CONFIG_USER_H
#include "../../config.h"
If you want to override a setting from the parent config.h
file, you need to #undef
and then #define
the setting again, like this:
#undef MY_SETTING
#define MY_SETTING 4
