- current_layer indicates active layer at the time - default_layer indicates base layer - default_layer is used when current_layer is 0 - with this LAYER_BIT action works as overlay even if default_layer varies other than layer 0. |

Build & Program
Install Tools
First, you need tools to build firmware and program your controller. I assume you are on Windows here.
-
Install WinAVR. This is old but works well for this purpose.
WinAVR
is a tool set to build firmware including C compiler(gcc) and make commands. You can use CrossPack instead if you are on Mac. -
Install Atmel FLIP.
FLIP
is a tool to program(load) firmware into AVR controller(ATMega32u4) via DFU bootloader. ATMega32u4 has DFU bootloader by factory default. You can use dfu-programmer instead if you are on Mac. -
Install driver for DFU bootloader. At first time you start DFU bootloader on Chip 'Found New Hardware Wizard' will come up on Windows. If you install device driver properly you can find chip name like 'ATmega32U4' under 'LibUSB-Win32 Devices' tree on 'Device Manager'. If not you shall need to update its driver on 'Device Manager'. You will find the driver in
FLIP
install directory like: C:\Program Files (x86)\Atmel\Flip 3.4.5\usb. If you usedfu-programmer
install its driver.
If you use PJRC Teensy you don't need step 2 and 3, just get Teensy loader.
Download source
You can find firmware source at github: https://github.com/tmk/tmk_keyboard
If you are familiar with Git
tools you are recommended to use it.
If not you can download zip archive from: https://github.com/tmk/tmk_keyboard/archive/master.zip
Build firmware
-
Open terminal window to get access to commands. You can use
cmd
in Windows orTerminal.app
on Mac OSX. In Windows pressWindows
key andR
then entercmd
in Run command dialog showing up. -
Move to project directory in the firmware source.
cd tmk_keyboard/{keyboard or converter}/
-
Build firmware using GNU
make
command. You'll see _.hex file in that directory unless something unexpected occurs in build process.mkae -f Makefile. clean make -f Makefile.
Program Controller
Sock AVR USB chip including ATmega32U4 has DFU bootloader by factory default, you can use DFU tools for this purpose. FLIP
is a DFU tool on Windows offered by Atmel. Open source command line DFU tool dfu-programmer
also supports AVR chips, which run on Linux, Mac OSX and even Windows. If you have a PJRC Teensy you should use Teensy Loader
.
DFU bootloader
To program AVR chip with DFU bootloader use FLIP
or dfu-programmer
.
If you have a proper program command in Makefile
just type this.
FLIP
has two version of tool, GUI app and command line program. If you want GUI see tutorial section below.
To use command line tool run this command. Note that you need to set PATH variable properly.
$ make -f Makefile.<variant> flip
To program with dfu-programmer
run:
$ make -f Makefile.<variant> dfu
Teensy
If you have PJRC Teensy see instruction of Teensy Loader
at: http://www.pjrc.com/teensy/loader.html
Or use this command if you have command line version of Teensy Loader installed.
$ make -f Makefile.<variant> teensy
Other programmer
You may want to use other you favorite programmer like avrdude
with AVRISPmkII, Aruduino or USBasp. In that case you can still use make target program
for build with configuring PROGRAM_CMD in Makefile.
$ make -f Makefile.<variant> program
FLIP GUI tutorial
-
On menu bar click Device -> Select, then.
ATmega32u4
. -
On menu bar click Settings -> Communication -> USB, then click 'Open' button on 'USB Port Connection' dialog. At this point you'll see greyouted widgets on the app get colored and ready.
-
On menu bar click File -> Load HEX File, then select your firmware hex file on File Selector dialog.
-
On 'Operations Flow' panel click 'Run' button to load the firmware binary to the chip. Note that you should keep 'Erase', 'Blank Check', 'Program' and 'Verify' check boxes selected.
-
Re-plug USB cord or click 'Start Application' button to restart your controller. Done.

Keymap
Many of existent projects offer keymap framework to define your own keymap easily. The following will explain how you can define keymap using this framework.
Instead, you can also implement your own keymap_get_action()
to return action code for each key if you want.
This is keymap example for HHKB keyboard. Keymap is defined in keymaps[]
array.
static const uint8_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {

1. Keycode
See common/keycode.h
. Keycode is 8bit internal code to inidicate action performed on key in keymap. Keycode has KC_
prefixed symbol respectively. Most of keycodes like KC_A
have simple action register key on press and unregister on release, on the other some of keycodes has some special actions like Fn keys, Media contorl keys, System control keys and Mouse keys.
In KEYMAP
definition you need to omit prefix part KC_
of keycode to keep keymap compact. For example, just use A
instead you place KC_A
in KEYMAP
. Some keycodes has 4-letter short name in addition to descriptive name, you'll prefer short one in KEYMAP
.

1.3 Fn key
KC_FNnn
are Fn
keys which not given any action at the beginning unlike most of keycodes has its own action. To use these keys in KEYMAP
you need to assign action you want at first. Action of Fn
is defined in fn_actions[]
and index of the array is identical with number part of KC_FNnn
. Thus KC_FN0
designates action defined in first element of the array. 32 Fn
keys can be defined at most.

Keycode Table
See keycode table in doc/keycode.txt
or common/keycode.h
for the detail or other keycodes.
In regard to implementation side most of keycodes are identical with [HID usage] sent to host for real and some virtual keycodes are defined to support special actions. [HID usage]: http://www.usb.org/developers/devclass_docs/Hut1_11.pdf
2. Action
See common/action.h
. Action is a 16bit code and defines function to perform on events of a key like press, release, hold and tap. You can define various actions to use various action codes.
Most of keys just register 8bit keycode as HID usage(or scan code) to host, but to support other complex features needs 16bit extended action codes internally. But using 16bit action codes in keymap results in double size in memory against keycodes. To avoid this waste 8bit keycodes are used in KEYMAP
to define instead of action codes. Keycodes can be considered as subset of action codes. Like KC_A
(0x04) is equal to a Key
action(0x0004) that transmit keycode of 'A'.
2.1 Key action
Key is simple action that registers keycode on press of key and unregister on release.
You can define Key
action on 'A' key with:
ACTION_KEY(KC_A)
But you don't need to use this expression directly because you can just put symbol A
in KEYMAP
definition.
Say you want to assign a key to Shift + 1
to get charactor '!' or Alt + Tab
to switch windows.
ACTION_MOD_KEY(KC_LSHIFT, KC_1)
ACTION_MOD_KEY(KC_LALT, KC_TAB)
Or Alt,Shift + Tab
can be defined.
ACTION_MODS_KEY((MOD_BIT(KC_LALT) | MOD_BIT(KC_LSHIFT)), KC_TAB)
These actions are comprised of strokes of modifiers and a key. Macro
action is needed if you want more complex key strokes.
2.2 Layer Actions
This sets default layer
into current layer
. With this action you can return to default layer
.
ACTION_LAYER_DEFAULT
Layer Set
action sets given layer argument to current layer
. Layer Set
action can take 0 to 15 as argument.
ACTION_LAYER_SET(layer)
ACTION_LAYER_SET_TOGGLE(layer)
ACTION_LAYER_SET_TAP_KEY(layer, key)
ACTION_LAYER_SET_TAP_TOGGLE(layer)
Layer Bit
action XOR given bits with current layer
. Layer Bit
action can take 0 to 15 as argument.
ACTION_LAYER_BIT(bits)
ACTION_LAYER_BIT_TOGGLE(bits)
ACTION_LAYER_BIT_TAP_KEY(bits, key)
ACTION_LAYER_BIT_TAP_TOGGLE(bits)
These acitons change default layer
.
ACTION_LAYER_SET_DEFAULT(layer)
ACTION_LAYER_BIT_DEFAULT(bits)
2.3 Macro action
NOT FIXED
Macro
action indicates complex key strokes.
MACRO( MD(LSHIFT), D(D), END )
MACRO( U(D), MU(LSHIFT), END )
MACRO( I(255), T(H), T(E), T(L), T(L), W(255), T(O), END )
2.3.1 Normal mode
- I() change interavl of stroke.
- D() press key
- U() release key
- T() type key(press and release)
- W() wait
- MD() modifier down
- MU() modifier up
- END end mark
2.3.2 Extended mode
TODO: sample impl
See keyboard/hhkb/keymap.c
for sample.
2.4 Function action
NOT FIXED
There are two type of action, normal Function
and tappable Function
.
These actions call user defined function with id
, opt
, and key event information as arguments.
2.4.1 Function
To define normal Function
action in keymap use this.
ACTION_FUNCTION(id, opt)
2.4.2 Function with tap
To define tappable Function
action in keymap use this.
ACTION_FUNCTION_TAP(id, opt)
2.4.3 Implement user function
Function
actions can be defined freely with C by user in callback function:
void keymap_call_function(keyrecord_t *event, uint8_t id, uint8_t opt)
This C function is called every time key is operated, argument id
selects action to be performed and opt
can be used for option. Functon id
can be 0-255 and opt
can be 0-15.
keyrecord_t
is comprised of key event and tap count. keyevent_t
indicates which and when key is pressed or released. From tap_count
you can know tap state, 0 means no tap. These information will be used in user function to decide how action of key is performed.
typedef struct {
keyevent_t event;
uint8_t tap_count;
} keyrecord_t;
typedef struct {
key_t key;
bool pressed;
uint16_t time;
} keyevent_t;
typedef struct {
uint8_t col;
uint8_t row;
} key_t;
TODO: sample impl
See keyboard/hhkb/keymap.c
for sample.
3. Layer
Layer is key-action map to assign action to every physical key. You can define multiple layers in keymap and select a layer out of keymap during operation at will.
First layer is indexed by Layer 0
which usually become default layer
and active in initial state. current layer
is active layer at that time and can be changed with user interaction. You can define 16 layers at most in default keymap framework.
you can define a layer with placing keycode symbols separated with comma
in KEYMAP
, which is formed with resemblance to physical keyboard layout so as you can easily put keycode on place you want to map. You can define most of keys with just using keycodes except for Fn
key serving special actions.
4. Layer switching
You can have some ways to switch layer with these actions.
There are two kind of layer switch action Layer Set
and Layer Bit
and two type of switching behaviour Momentary and Toggle.
4.1 Momentary switching
Momentary switching changes layer only while holding Fn key.
4.1.1 Momentary Set
This Layer Set
action sets new layer Layer 1
to current layer
on key press event.
ACTION_LAYER_SET(1)
It switches to destination layer immediately when key is pressed, after that actions on keymap of destination layer is perfomed. Thus you shall need to place action to come back on destination layer, or you will be stuck in destination layer without way to get back. To get back to default layer
you can use this action.
ACTION_LAYER_DEFAULT
4.1.2 Momentary Bit
This Layer Bit
action performs XOR 1
with current layer
on both press and release event. If you are on Layer 0
now next layer to switch will be Layer 1
. To come back to previous layer you need to place same action on destination layer.
ACTION_LAYER_BIT(1)
4.2 Toggle switching
Toggle switching changes layer after press then release. You keep being on the layer until you press key to return.
4.2.1 Toggle Set
This Layer Set Toggle
action is to set Layer 1
to current layer
on release and do none on press.
ACTION_LAYER_SET_TOGGLE(1)
To get back to default layer
you can use this action.
ACTION_LAYER_DEFAULT
4.2.2 Toggle Bit
This Layer Bit Toggle
action is to XOR 1
with current layer
on release and do none on press. If you are on Layer 2
you'll switch to Layer 3
on press. To come back to previous layer you need to place same action on destination layer.
ACTION_LAYER_BIT_TOGGLE(1)
4.3 Momentary switching with Tap key
These actions switch to layer only while holding Fn
key and register key on tap. Tap means to press and release key quickly.
ACTION_LAYER_SET_TAP_KEY(2, KC_SCLN)
ACTION_LAYER_SET_BIT_KEY(2, KC_SCLN)
With these you can place layer switching function on normal alphabet key like ;
without losing its original register function.
4.4 Momentary switching with Tap Toggle
This changes layer only while holding Fn
key and toggle layer after several taps. Tap means to press and release key quickly.
ACTION_LAYER_SET_TAP_TOGGLE(layer)
ACTION_LAYER_BIT_TAP_TOGGLE(layer)
Number of taps can be defined with TAPPING_TOGGLE
in config.h
, 5
by default.
Legacy Keymap
This was used in prior version and still works due to legacy support code in common/keymap.c
. Legacy keymap doesn't support many of features that new keymap offers.
In comparison with new keymap how to define Fn key is different. It uses two arrays fn_layer[]
and fn_keycode[]
. The index of arrays corresponds with postfix number of Fn
key. Array fn_layer[]
indicates destination layer to switch and fn_keycode[]
has keycodes to send when tapping Fn
key.
In following setting example, Fn0
, Fn1
and Fn2
switch layer to 1, 2 and 2 respectively. Fn2
registers Space
key when tap while Fn0
and Fn1
doesn't send any key.
static const uint8_t PROGMEM fn_layer[] = {
1, // Fn0
2, // Fn1
2, // Fn2
};
static const uint8_t PROGMEM fn_keycode[] = {
KC_NO, // Fn0
KC_NO, // Fn1
KC_SPC, // Fn2
};
Debuging
Use PJRC's hid_listen
to see debug messages. You can use the tool for debug even if firmware use LUFA stack.
You will see output from firmware like this.
