Download and Install
--------------------
### 1. Install Tools
First, you need tools to build firmware and program your controller. I assume you are on Windows here.

1. **Toolchain** 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. **Programmer** Install [Atmel FLIP][flip]. `FLIP` is a tool to program(load) firmware into AVR controller via DFU bootloader. AVR USB chips including ATmega32U4 has DFU bootloader by factory default. You can also use [dfu-programmer][dfu-prog] instead if you are on Mac or Linux.

3. **Driver** 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 above, just get [Teensy loader][teensy-loader].


### 2. 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 but you can also download zip archive from: 

- <https://github.com/tmk/tmk_keyboard/archive/master.zip>


Build firmware
--------------
### 1. Open terminal
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. Change directory
Move to project directory in the firmware source.

    cd tmk_keyboard/{'keyboard' or 'converter'}/<project>

### 3. Make
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
------------------
Now you have **hex** file to program on current directory. This **hex** is only needed to program your controller, other files are used for development and you may leave and forget them.

### 1. Start bootloader
How to program controller depends on controller chip and its board design. To program AVR USB chips you'll need to start it up in bootloader mode. Most of boards with the chip have a push button to let bootloader come up. Consult with your controller board manual.

### 2. Program with DFU bootloader
Stock AVR USB chip including ATmega32U4 has DFU bootloader by factory default. `FLIP` is a DFU programmer on Windows offered by Atmel. Open source command line tool `dfu-programmer` also supports AVR chips, it runs on Linux, Mac OSX and even Windows.

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 below.
To use command line tool run this command. Note that you need to set PATH variable properly.

    $ make -f Makefile.<variant> flip

Or to program with `dfu-programmer` run:

    $ make -f Makefile.<variant> dfu

#### 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.

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.

### 3. Program with Teensy Loader
If you have PJRC Teensy see instruction of `Teensy Loader`.

- <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


### 4. Program with Other programmer
You may want to use other 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

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

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
