TMK Keyboard Firmware Collection
This is a keyboard firmware with some useful features for Atmel AVR controller.
Source code is available here: http://github.com/tmk/tmk_keyboard
Core library was separated to other branch
Makefile you need to set
TMK_DIR to indicate core library location now.
TMK_DIR = ../../tmk_core
These features can be used in your keyboard.
- Multi-layer Keymap - Multiple keyboard layouts with layer switching
- Mouse key - Mouse control with keyboard
- System Control Key - Power Down, Sleep, Wake Up and USB Remote Wake up
- Media Control Key - Volume Down/Up, Mute, Next/Prev track, Play, Stop and etc
- USB NKRO - 120 keys(+ 8 modifiers) simultaneously
- PS/2 mouse support - PS/2 mouse(TrackPoint) as composite device
- Keyboard protocols - PS/2, ADB, M0110, Sun and other old keyboard protocols
- User Function - Customizable function of key with writing code
- Macro - Very primitive at this time
- Keyboard Tricks - Oneshot modifier and modifier with tapping feature
- Debug Console - Messages for debug and interaction with firmware
- Virtual DIP Switch - Configurations stored EEPROM(Boot Magic)
- Locking CapsLock - Mechanical switch support for CapsLock
- Breathing Sleep LED - Sleep indicator with charm during USB suspend
- Backlight - Control backlight levels

Build Firmware and Program Controller
Change your keymap
To see help press
Magic key combination is
RShift in many project, but
Power key on ADB converter.
Magic keybind can be vary on each project, check
config.h in project directory.
Following commands can be also executed with
Magic + key. In console mode
Magic keybind is not needed.
----- Command Help ----- c: enter console mode d: toggle debug enable x: toggle matrix debug k: toggle keyboard debug m: toggle mouse debug v: print device version & info t: print timer count s: print status e: print eeprom config n: toggle NKRO 0/F10: switch to Layer0 1/F1: switch to Layer1 2/F2: switch to Layer2 3/F3: switch to Layer3 4/F4: switch to Layer4 PScr: power down/remote wake-up Caps: Lock Keyboard(Child Proof) Paus: jump to bootloader
Boot Magic Configuration - Virtual DIP Switch
Boot Magic are executed during boot up time. Press Magic key below then plug in keyboard cable. Note that you must use keys of Layer 0 as Magic keys. These settings are stored in EEPROM so that retain your configure over power cycles.
To avoid configuring accidentally additive salt key
KC_SPACE also needs to be pressed along with the following configuration keys. The salt key is configurable in
config.h. See tmk_core/common/bootmagic.h.
- Skip reading EEPROM to start with default configuration(
- Clear configuration stored in EEPROM to reset configuration(
- Kick up Bootloader(
- Debug enable(
- Debug matrix enable(
- Debug keyboard enable(
- Debug mouse enable(
- Swap Control and CapsLock(
- Change CapsLock to Control(
- Swap LeftAlt and Gui(
- Swap RightAlt and Gui(
- Disable Gui(
- Swap Grave and Escape(
- Swap BackSlash and BackSpace(
- Enable NKRO on boot(
- Set Default Layer to 0(
- Set Default Layer to 1(
- Set Default Layer to 2(
- Set Default Layer to 3(
- Set Default Layer to 4(
- Set Default Layer to 5(
- Set Default Layer to 6(
- Set Default Layer to 7(
Mechanical Locking support
This feature makes it possible for you to use mechanical locking switch for
ScrollLock. To enable this feature define these macros in
config.h and use
KC_LSCR in keymap for locking key instead of normal
ync option tries to keep switch state consistent with keyboard LED state.
#define LOCKING_SUPPORT_ENABLE #define LOCKING_RESYNC_ENABLE

hid_listen to see debug messages. You can use the tool for debug even if firmware use LUFA stack.
You can use xprintf() to display debug info on
