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.
Basic QMK structure
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
Keyboard project structure
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 built
rules.mk: The file that sets the default "make" options. Do not edit this file directly, instead use a keymap specific
config.h: The file that sets the default compile time options. Do not edit this file directly, instead use a keymap specific
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 keymap
keymap.c: all of your keymap code, required
rules.mk: the features of QMK that are enabled
readme.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
- keyboard (
- keymap (
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_common.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:
