-Build & Program
----------------
-### Install Tools
-First, you need tools to build firmware and program your controller. I assume you are on Windows here.
-
-1. Install [WinAVR][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][crosspack] instead if you are on Mac.
-
-2. Install [Atmel FLIP][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][dfu-prog] instead if you are on Mac.
-
-3. 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 use `dfu-programmer` install its driver.
-
-If you use PJRC Teensy you don't need step 2 and 3, just get [Teensy loader][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
-1. Open terminal window to get access to commands. You can use `cmd` in Windows or `Terminal.app` on Mac OSX. In Windows press `Windows` key and `R` then enter `cmd` in Run command dialog showing up.
-
-2. Move to project directory in the firmware source.
-
- cd tmk_keyboard/{keyboard or converter}/<project>
-
-3. Build firmware using GNU `make` command. You'll see <project>_<variant>.hex file in that directory unless something unexpected occurs in build process.
-
- mkae -f Makefile.<variant> clean
- make -f Makefile.<variant>
-
-
-
-
-### 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:
+License
+-------
+**GPLv2** or later. Some protocol files are under **Modified BSD License**.
+LUFA, PJRC and V-USB stack have their own license respectively.
- $ 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
+Build Firmware and Program Controller
+-------------------------------------
+See [doc/build.md](doc/build.md).
-#### 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
+Change your keymap
+------------------
+See [doc/keymap.md](doc/keymap.md).
-#### FLIP GUI tutorial
-1. On menu bar click Device -> Select, then. `ATmega32u4`.
-2. 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.
+Magic Commands
+--------------
+To see help press `Magic` + `H`.
-3. On menu bar click File -> Load HEX File, then select your firmware hex file on File Selector dialog.
-4. 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.
-5. Re-plug USB cord or click 'Start Application' button to restart your controller.
-Done.
+ `Magic` key bind may be `LShift` + `RShift` in many project, but `Power` key on ADB converter. `Magic` keybind can be vary on each project, check `config.h` in project directory.
-See also these instaructions if you need.
+Following commands can be also executed with `Magic` + key. In console mode `Magic` keybind is not needed.

+Mechanical Locking support
+--------------------------
+This feature makes it possible for you to use mechanical switch for `CapsLock`, `NumLock` or `ScrollLock`. To enable this feature define these macros in `config.h` and use `KC_LCAP`, `KC_LNUM` or `KC_LSCR` in keymap for locking key instead of normal `KC_CAPS`, `KC_NLCK` or `KC_SLCK`. Resync option tries to keep lock switch state consistent with keyboard LED state.

-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](http://en.wikipedia.org/wiki/Happy_Hacking_Keyboard) keyboard. Keymap is defined in `keymaps[]` array.

-### 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`.
-
-#### 1.1 Normal key
-- `KC_NO` for no aciton
-- `KC_A` to `KC_Z`, `KC_1` to `KC_0` for alpha numeric key
-- `KC_MINS`, `KC_EQL`, `KC_GRV`, `KC_RBRC`, `KC_LBRC`, `KC_COMM`, `KC_DOT`, `KC_BSLS`, `KC_SLSH`, `KC_SCLN`, `KC_QUOT`
-- `KC_ESC`, `KC_TAB`, `KC_SPC`, `KC_BSPC`, `KC_ENT`, `KC_DEL`, `KC_INS`
-- `KC_UP`, `KC_DOWN`, `KC_RGHT`, `KC_LEFT`, `KC_PGUP`, `KC_PGDN`, `KC_HOME`, `KC_END`
-- `KC_CAPS`, `KC_NLCK`, `KC_SLCK`, `KC_PSCR`, `KC_PAUS`, `KC_APP`, `KC_F1` to `KC_F24`
-- `KC_P1` to `KC_P0`, `KC_PDOT`, `KC_PCMM`, `KC_PSLS`, `KC_PAST`, `KC_PMNS`, `KC_PPLS`, `KC_PEQL`, `KC_PENT` for keypad.
-
-#### 1.2 Modifier
-There are 8 modifiers which has discrimination between left and right.
-
-- `KC_LCTL` and `KC_RCTL` for Control
-- `KC_LSFT` and `KC_RSFT` for Shift
-- `KC_LALT` and `KC_RALT` for Alt
-- `KC_LGUI` and `KC_RGUI` for Windows key or Command key in Mac
-
-#### 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.***
-
-#### 1.4 Mousekey
-- `KC_MS_U`, `KC_MS_D`, `KC_MS_L`, `KC_MS_R` for mouse cursor
-- `KC_WH_U`, `KC_WH_D`, `KC_WH_L`, `KC_WH_R` for mouse wheel
-- `KC_BTN1`, `KC_BTN2`, `KC_BTN3`, `KC_BTN4`, `KC_BTN5` for mouse buttons
-
-#### 1.5 System & Media key
-- `KC_PWR`, `KC_SLEP`, `KC_WAKE` for Power, Sleep, Wake
-- `KC_MUTE`, `KC_VOLU`, `KC_VOLD` for audio volume control
-- `KC_MNXT`, `KC_MPRV`, `KC_MSTP`, `KC_MPLY`, `KC_MSEL` for media control
-- `KC_MAIL`, `KC_CALC`, `KC_MYCM` for application launch
-- `KC_WSCH`, `KC_WHOM`, `KC_WBAK`, `KC_WFWD`, `KC_WSTP`, `KC_WREF`, `KC_WFAV` for web browser operation
-
-#### Keycode Table
- See [keycode table](doc/keycode.txt) 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 bits with `current layer`. `Layer Bit` action can take 0 to 8 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 )

-
-#### 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;

-### 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.

+ +---------------------------------------------+ Keyboard
- 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
- };
