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:

    $ 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
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.

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

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 -----
