   1 Alternative Controller for HHKB Pro
   2 ===================================
   3 I wanted to add some features like vi cursor and mouse keys to my [HHKB][HHKB] but its controller is not programmable and firmware source code is not open, of course. This means customizing this keyboard needs to replace original controller with programmable one.
   4
   5 This controller can work with HHKB **Professional**, **Professional** 2, **JP** and **Type-S**.

   7 See [this thread][AltController] in geekhack.org.

  23 ###Pros
  24 * No risks: Everything is all reversible
  25 * No need for PCB trace patching, case cutting or any other destructive mod
  26 * Can keep original controller intact
  27 * Can change all HHKB behavior as you like
  28
  29 ###Cons
  30 * Void your warranty
  31 * Lose USB hub function of Pro2

  33 ##DISCLAIMER
  34 I'm not a professional of electronics nor MCU programming. This may damage your HHKB.
  35 And my English writing is poor, I'm not sure I can convey my notions accurately.

  38 ##Documents
  39 See [doc/HHKB.txt](doc/HHKB.txt) and files under [doc/](doc/) for internal of HHKB and this controller.
  40
  41
  42 ##Build Firmware & Program
  43 See [this document](../../doc/build.md) first.
  44
  45 ### Configuration
  46 Set `MCU`, `BOOTLOADER_SIZE` and other build options in `Makefile` and `config.h`. If your target is **HHKB JP** you need to set `HHKB_JP` build option in `Makefile`.
  47
  48 ### Build
  49 Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. Just `make` with `KEYMAP` option like:
  50
  51     $ make KEYMAP=[hasu|hhkb|spacefn|<name>]
  52
  53
  54 ### Program
  55 First, push reset button on board to start bootloader.
  56
  57 This command programs the controller with [dfu-programmer] if the tool is installed and configured properly.
  58
  59     $ make dfu
  60
  61 Or you can also use [FLIP] command to program. Also the tool should be installed and configured properly. FLIP GUI application is also available.
  62
  63     $ make flip
  64
  65 Use [Teensy Loader] if your controller is Teensy/Teensy++.
  66
  67
  68 ##Keymap
  69 To define your own keymap create file named `keymap_<name>.c` and see [keymap document](../../doc/keymap.md) and existent keymap files.
  70
  71
  72 ##Hardware
  73 You have some options for hardware. Development boards with USB AVR family(ATMega32U4, AT90USB1286) like Teensy will work while MegaAVR with [V-USB] library is also cheaper option for DIY.
  74
  75 ###1. TMK Alt Controller Board
  76 Design files are available at [Keyboard Controller Board for HHKB(KiCad project)](https://github.com/tmk/HHKB_controller) and see [Controller Distribution thread](http://geekhack.org/index.php?topic=56494.0) if you get an assembled one.

  79 ###2. PJRC Teensy
  80 See [this thread](http://geekhack.org/index.php?topic=57008.0).
  81
  82
  83 ###3. V-USB version
  84 See [V-USB controller for HHKB](doc/V-USB.md).
