Configuring QMK

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.

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:

QMK Default
Keyboard
Folders (Up to 5 levels deep)
Keymap

QMK Default

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.

Keyboard

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.

Folders

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

This level 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.

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. The config.h file shouldn't be including other config.h files, or anything besides this:

#include "config_common.h"

Features That Can Be Disabled

If you define these options you will disable the associated feature, which can save on code size.

#define NO_DEBUG
- disable debugging
#define NO_PRINT
- disable printing/debugging using hid_listen
#define NO_ACTION_LAYER
- disable layers
#define NO_ACTION_TAPPING
- disable tap dance and other tapping features
#define NO_ACTION_ONESHOT
- disable one-shot modifiers
#define NO_ACTION_MACRO
- disable old style macro handling: MACRO() & action_get_macro
#define NO_ACTION_FUNCTION
- disable calling of action_function() from the fn_actions array (deprecated)

Features That Can Be Enabled

If you define these options you will enable the associated feature, which may increase your code size.

#define FORCE_NKRO
- NKRO by default requires to be turned on, this forces it on during keyboard startup regardless of EEPROM setting. NKRO can still be turned off but will be turned on again if the keyboard reboots.
#define STRICT_LAYER_RELEASE
- force a key release to be evaluated using the current layer stack instead of remembering which layer it came from (used for advanced cases)

Behaviors That Can Be Configured

#define TAPPING_TERM 200
- how long before a tap becomes a hold, if set above 500, a key tapped during the tapping term will turn it into a hold too
#define TAPPING_TERM_PER_KEY
- enables handling for per key TAPPING_TERM settings
#define RETRO_TAPPING
- tap anyway, even after TAPPING_TERM, if there was no other key interruption between press and release
- See Retro Tapping for details
#define TAPPING_TOGGLE 2
- how many taps before triggering the toggle
#define PERMISSIVE_HOLD
- makes tap and hold keys trigger the hold if another key is pressed before releasing, even if it hasn't hit the TAPPING_TERM
- See Permissive Hold for details
#define IGNORE_MOD_TAP_INTERRUPT
- makes it possible to do rolling combos (zx) with keys that convert to other keys on hold, by enforcing the TAPPING_TERM for both keys.
- See Mod tap interrupt for details
#define IGNORE_MOD_TAP_INTERRUPT_PER_KEY
- enables handling for per key IGNORE_MOD_TAP_INTERRUPT settings
#define TAPPING_FORCE_HOLD
- makes it possible to use a dual role key as modifier shortly after having been tapped
- See Hold after tap
- Breaks any Tap Toggle functionality (TT or the One Shot Tap Toggle)
#define LEADER_TIMEOUT 300
- how long before the leader key times out
  - If you're having issues finishing the sequence before it times out, you may need to increase the timeout setting. Or you may want to enable the LEADER_PER_KEY_TIMING option, which resets the timeout after each key is tapped.
#define LEADER_PER_KEY_TIMING
- sets the timer for leader key chords to run on each key press rather than overall
#define LEADER_KEY_STRICT_KEY_PROCESSING
- Disables keycode filtering for Mod-Tap and Layer-Tap keycodes. Eg, if you enable this, you would need to specify MT(MOD_CTL, KC_A) if you want to use KC_A.
#define ONESHOT_TIMEOUT 300
- how long before oneshot times out
#define ONESHOT_TAP_TOGGLE 2
- how many taps before oneshot toggle is triggered
#define QMK_KEYS_PER_SCAN 4
- Allows sending more than one key per scan. By default, only one key event gets sent via process_record() per scan. This has little impact on most typing, but if you're doing a lot of chords, or your scan rate is slow to begin with, you can have some delay in processing key events. Each press and release is a separate event. For a keyboard with 1ms or so scan times, even a very fast typist isn't going to produce the 500 keystrokes a second needed to actually get more than a few ms of delay from this. But if you're doing chording on something with 3-4ms scan times? You probably want this.
#define COMBO_COUNT 2
- Set this to the number of combos that you're using in the Combo feature.
#define COMBO_TERM 200
- how long for the Combo keys to be detected. Defaults to TAPPING_TERM if not defined.
#define TAP_CODE_DELAY 100
- Sets the delay between register_code and unregister_code, if you're having issues with it registering properly (common on VUSB boards). The value is in milliseconds.
#define TAP_HOLD_CAPS_DELAY 80
- Sets the delay for Tap Hold keys (LT, MT) when using KC_CAPSLOCK keycode, as this has some special handling on MacOS. The value is in milliseconds, and defaults to 80 ms if not defined. For macOS, you may want to set this to 200 or higher.

RGB Light Configuration

#define RGB_DI_PIN D7
- pin the DI on the WS2812 is hooked-up to
#define RGBLIGHT_ANIMATIONS
- run RGB animations
#define RGBLED_NUM 12
- number of LEDs
#define RGBLIGHT_SPLIT
- Needed if both halves of the board have RGB LEDs wired directly to the RGB output pin on the controllers instead of passing the output of the left half to the input of the right half
#define RGBLED_SPLIT { 6, 6 }
- number of LEDs connected that are directly wired to RGB_DI_PIN on each half of a split keyboard
- First value indicates number of LEDs for left half, second value is for the right half
- When RGBLED_SPLIT is defined, RGBLIGHT_SPLIT is implicitly defined.
#define RGBLIGHT_HUE_STEP 12
- units to step when in/decreasing hue
#define RGBLIGHT_SAT_STEP 25
- units to step when in/decreasing saturation
#define RGBLIGHT_VAL_STEP 12
- units to step when in/decreasing value (brightness)
#define RGBW

Mouse Key Options

#define MOUSEKEY_INTERVAL 20
#define MOUSEKEY_DELAY 0
#define MOUSEKEY_TIME_TO_MAX 60
#define MOUSEKEY_MAX_SPEED 7
#define MOUSEKEY_WHEEL_DELAY 0

Split Keyboard Options

Split Keyboard specific options, make sure you have 'SPLIT_KEYBOARD = yes' in your rules.mk

SPLIT_TRANSPORT = custom
- Allows replacing the standard split communication routines with a custom one. ARM based split keyboards must use this at present.

Setting Handedness

One thing to remember, the side that the USB port is plugged into is always the master half. The side not plugged into USB is the slave.

There are a few different ways to set handedness for split keyboards (listed in order of precedence):

Set SPLIT_HAND_PIN: Reads a pin to determine handedness. If pin is high, it's the left side, if low, the half is determined to be the right side
Set EE_HANDS and flash eeprom-lefthand.eep/eeprom-righthand.eep to each half
- For boards with DFU bootloader you can use :dfu-split-left/:dfu-split-right to flash these EEPROM files
- For boards with Caterina bootloader (like stock Pro Micros), use :avrdude-split-left/:avrdude-split-right
- For boards with ARM DFU bootloader (like Proton C), use :dfu-util-split-left/:dfu-util-split-right
Set MASTER_RIGHT: Half that is plugged into the USB port is determined to be the master and right half (inverse of the default)
Default: The side that is plugged into the USB port is the master half and is assumed to be the left half. The slave side is the right half

Defines for handedness

#define SPLIT_HAND_PIN B7
- For using high/low pin to determine handedness, low = right hand, high = left hand. Replace B7 with the pin you are using. This is optional, and if you leave SPLIT_HAND_PIN undefined, then you can still use the EE_HANDS method or MASTER_LEFT / MASTER_RIGHT defines like the stock Let's Split uses.
#define EE_HANDS (only works if SPLIT_HAND_PIN is not defined)
- Reads the handedness value stored in the EEPROM after eeprom-lefthand.eep/eeprom-righthand.eep has been flashed to their respective halves.
#define MASTER_RIGHT
- Master half is defined to be the right half.

Other Options

#define USE_I2C
- For using I2C instead of Serial (defaults to serial)
#define SOFT_SERIAL_PIN D0
- When using serial, define this. D0 or D1,D2,D3,E6.
#define MATRIX_ROW_PINS_RIGHT { <row pins> }
#define MATRIX_COL_PINS_RIGHT { <col pins> }
- If you want to specify a different pinout for the right half than the left half, you can define MATRIX_ROW_PINS_RIGHT/MATRIX_COL_PINS_RIGHT. Currently, the size of MATRIX_ROW_PINS must be the same as MATRIX_ROW_PINS_RIGHT and likewise for the definition of columns.
#define DIRECT_PINS_RIGHT { { F1, F0, B0, C7 }, { F4, F5, F6, F7 } }
- If you want to specify a different direct pinout for the right half than the left half, you can define DIRECT_PINS_RIGHT. Currently, the size of DIRECT_PINS must be the same as DIRECT_PINS_RIGHT.
#define RGBLED_SPLIT { 6, 6 }
- See RGB Light Configuration
#define SELECT_SOFT_SERIAL_SPEED <speed> (default speed is 1)
- Sets the protocol speed when using serial communication
- Speeds:
  - 0: about 189kbps (Experimental only)
  - 1: about 137kbps (default)
  - 2: about 75kbps
  - 3: about 39kbps
  - 4: about 26kbps
  - 5: about 20kbps
#define SPLIT_USB_DETECT
- Detect (with timeout) USB connection when delegating master/slave
- Default behavior for ARM
- Required for AVR Teensy
#define SPLIT_USB_TIMEOUT 2500
- Maximum timeout when detecting master/slave when using SPLIT_USB_DETECT

The `rules.mk` File

This is a make 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.

Build Options

DEFAULT_FOLDER
- Used to specify a default folder when a keyboard has more than one sub-folder.
FIRMWARE_FORMAT
- Defines which format (bin, hex) is copied to the root qmk_firmware folder after building.
SRC
- Used to add files to the compilation/linking list.
LIB_SRC
- Used to add files as a library to the compilation/linking list.
  The files specified by LIB_SRC is linked after the files specified by SRC.
  For example, if you specify:
```
SRC += a.c
LIB_SRC += lib_b.c
SRC += c.c
LIB_SRC += lib_d.c
```
  The link order is as follows.
```
 ...  a.o c.o  ...  lib_b.a lib_d.a  ...
```
LAYOUTS
- A list of layouts this keyboard supports.
LINK_TIME_OPTIMIZATION_ENABLE
- Enables Link Time Optimization (LTO) when compiling the keyboard. This makes the process take longer, but can significantly reduce the compiled size (and since the firmware is small, the added time is not noticeable). However, this will automatically disable the old Macros and Functions features automatically, as these break when LTO is enabled. It does this by automatically defining NO_ACTION_MACRO and NO_ACTION_FUNCTION
LTO_ENABLE
- It has the same meaning as LINK_TIME_OPTIMIZATION_ENABLE. You can use LTO_ENABLE instead of LINK_TIME_OPTIMIZATION_ENABLE.

AVR MCU Options

MCU = atmega32u4
F_CPU = 16000000
ARCH = AVR8
F_USB = $(F_CPU)
OPT_DEFS += -DINTERRUPT_CONTROL_ENDPOINT
BOOTLOADER = atmel-dfu with the following options:
- atmel-dfu
- lufa-dfu
- qmk-dfu
- halfkay
- caterina
- bootloadHID
- USBasp

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.

BOOTMAGIC_ENABLE
- Virtual DIP switch configuration
MOUSEKEY_ENABLE
- Mouse keys
EXTRAKEY_ENABLE
- Audio control and System control
CONSOLE_ENABLE
- Console for debug
COMMAND_ENABLE
- Commands for debug and configuration
COMBO_ENABLE
- Key combo feature
NKRO_ENABLE
- USB N-Key Rollover - if this doesn't work, see here: https://github.com/tmk/tmk_keyboard/wiki/FAQ#nkro-doesnt-work
AUDIO_ENABLE
- Enable the audio subsystem.
RGBLIGHT_ENABLE
- Enable keyboard underlight functionality
LEADER_ENABLE
- Enable leader key chording
MIDI_ENABLE
- MIDI controls
UNICODE_ENABLE
- Unicode
BLUETOOTH_ENABLE
- Legacy option to Enable Bluetooth with the Adafruit EZ-Key HID. See BLUETOOTH
BLUETOOTH
- Current options are AdafruitEzKey, AdafruitBLE, RN42
SPLIT_KEYBOARD
- Enables split keyboard support (dual MCU like the let's split and bakingpy's boards) and includes all necessary files located at quantum/split_common
CUSTOM_MATRIX
- Allows replacing the standard matrix scanning routine with a custom one.
DEBOUNCE_TYPE
- Allows replacing the standard key debouncing routine with an alternative or custom one.
WAIT_FOR_USB
- Forces the keyboard to wait for a USB connection to be established before it starts up
NO_USB_STARTUP_CHECK
- Disables usb suspend check after keyboard startup. Usually the keyboard waits for the host to wake it up before any tasks are performed. This is useful for split keyboards as one half will not get a wakeup call but must send commands to the master.

USB Endpoint Limitations

In order to provide services over USB, QMK has to use USB endpoints. These are a finite resource: each microcontroller has only a certain number. This limits what features can be enabled together. If the available endpoints are exceeded, a build error is thrown.

The following features can require separate endpoints:

MOUSEKEY_ENABLE
EXTRAKEY_ENABLE
CONSOLE_ENABLE
NKRO_ENABLE
MIDI_ENABLE
RAW_ENABLE
VIRTSER_ENABLE

In order to improve utilisation of the endpoints, the HID features can be combined to use a single endpoint. By default, MOUSEKEY, EXTRAKEY, and NKRO are combined into a single endpoint.

The base keyboard functionality can also be combined into the endpoint, by setting KEYBOARD_SHARED_EP = yes. This frees up one more endpoint, but it can prevent the keyboard working in some BIOSes, as they do not implement Boot Keyboard protocol switching.

Combining the mouse also breaks Boot Mouse compatibility. The mouse can be uncombined by setting MOUSE_SHARED_EP = no if this functionality is required.
