TMK Keyboard Firmware Collection
================================
This repository includes keyboard and converter firmware projects built with [`tmk_core`][tmk_core] keyboard library.

The latest source code is available here: <http://github.com/tmk/tmk_keyboard>


Updates
-------
#### 2016/06/26
Keymap framework was updated. `fn_actions[]` should be defined as `action_t` instead of `uint16_t`. And default code for keymap handling is now included in core you just need define `uint8_t keymaps[][MATRIX_ROWS][MATRIX_COLS]` and `action_t fn_actions[]`.


#### 2016/06/22
Some projects were moved from `converter` and `keyboard` to `orphan` directory. Those might be removed in some future but you will be able to access them with `orphans` tag. See <https://github.com/tmk/tmk_keyboard/issues/173>

#### 2016/02/10
core: flabbergast's Chibios protocol was merged from <https://github.com/flabbergast/tmk_keyboard/tree/chibios> (@72b1668). See [tmk_core/protocol/chibios/README.md](tmk_core/protocol/chibios/README.md). Chibios protocol supports Cortex-M such as STM32 and Kinetis.

#### 2015/04/22
Core library was separated to other branch `core`. <https://github.com/tmk/tmk_keyboard/tree/core>

In `Makefile` you need to set `TMK_DIR` to indicate core library location now.

    TMK_DIR = ../../tmk_core

Build Firmware and Program Controller
-------------------------------------
See [tmk_core/doc/build.md](tmk_core/doc/build.md).



Change your keymap
------------------
See [tmk_core/doc/keymap.md](tmk_core/doc/keymap.md).



Magic Commands
--------------
To see help press `Magic` + `H`.

`Magic` key combination is `LShift` + `RShift` in many projects, 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](tmk_core/common/bootmagic.h).

#### General
- Skip reading EEPROM to start with default configuration(`ESC`)
- Clear configuration stored in EEPROM to reset configuration(`Backspace`)

#### Bootloader
- Kick up Bootloader(`B`)

#### Debug
- Debug enable(`D`)
- Debug matrix enable(`D`+`X`)
- Debug keyboard enable(`D`+`K`)
- Debug mouse enable(`D`+`M`)

#### Keymap
- Swap Control and CapsLock(`Left Control`)
- Change CapsLock to Control(`Caps Lock`)
- Swap LeftAlt and Gui(`Left Alt`)
- Swap RightAlt and Gui(`Right Alt`)
- Disable Gui(`Left Gui`)
- Swap Grave and Escape(`Grave`)
- Swap BackSlash and BackSpace(`Back Slash`)
- Enable NKRO on boot(`N`)

#### Default Layer
- Set Default Layer to 0(`0`)
- Set Default Layer to 1(`1`)
- Set Default Layer to 2(`2`)
- Set Default Layer to 3(`3`)
- Set Default Layer to 4(`4`)
- Set Default Layer to 5(`5`)
- Set Default Layer to 6(`6`)
- Set Default Layer to 7(`7`)



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

    #define LOCKING_SUPPORT_ENABLE
    #define LOCKING_RESYNC_ENABLE



Start Your Own Project
-----------------------
1. Add `tmk_core` into your repository using `git submodule` or `git subtree`.
2. Copy files from `tmk_keybaord` or other project similar to yours
3. Edit those files to support your keyboard.

See these as examples.

- https://github.com/tmk/whitefox



Debugging
--------
Use PJRC's `hid_listen` to see debug messages. You can use xprintf() to display debug info, see `tmk_core/common/xprintf.h`.
