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



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



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

 `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.

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
    p:      toggle print enable
    v:      print device version & info
    t:      print timer count
    s:      print status
    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

**TBD**

### Conguration with Boot Magic
Boot Magic are executed during boot up time. Press Magic key below then pulgin keyboard cable.
These settings are stored in EEPROM.

- Clear configuration stored in EEPROM(`Backspace`)
- Kick up Bootloader(`B`)
- Debug enable(`D`)
- Swap Control and CapsLock(`Left Control`)
- Change CapsLock to Control(`Casp 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`)

**TBD**


Mechanical Locking support for CapsLock
---------------------------------------
To enable this feature define these two macros in `config.h` and use `KC_LCAP` for locking CapsLock in keymap instead of normal `KC_CAPS`. Resync option tries to keep lock switch state consistent with keyboard LED state.
 
    #define CAPSLOCK_LOCKING_ENABLE
    #define CAPSLOCK_LOCKING_RESYNC_ENABLE

    #define VENDOR_ID       0xFEED
    #define PRODUCT_ID      0xBEEF
    #define MANUFACTURER    t.m.k.
    #define PRODUCT         Macway mod
    #define DESCRIPTION     t.m.k. keyboard firmware for Macway mod

#### 2. Keyboard matrix configuration

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.

    r/c 01234567
    00: 00000000
    01: 00000000
    02: 00000000
