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.
5 This controller can work with HHKB **Professional**, **Professional** 2, **JP** and **Type-S**.
7 See [this thread][AltController] in geekhack.org.

14 * Bluetooth module RN-42 is supported.(2015/01)
15 * V-USB and iWRAP are no longer supported now, but still it'll works with a little fix. See not_supported directory.(2015/01)
20 * More keymap layers(more Fn keys)
25 See README of [tmk_keyboard] for more.

30 * No risks: Everything is all reversible
31 * No need for PCB trace patching, case cutting or any other destructive mod
32 * Can keep original controller intact
33 * Can change all HHKB behavior as you like
37 * Lose USB hub function of Pro2
40 I'm not a professional of electronics nor MCU programming. This may damage your HHKB.
41 And my English writing is poor, I'm not sure I can convey my notions accurately.
45 See [doc/HHKB.txt](doc/HHKB.txt) and files under [doc/](doc/) for internal of HHKB and this controller.
48 ##Build Firmware & Program
49 See [this document](../../doc/build.md) first.
52 If your target is **HHKB JP** you need to set `HHKB_JP` build option in `Makefile` or use `Makefile.jp` instead of `Makefile`.
54 If you use other than **TMK Alt Controller Board** set proper `MCU`, `BOOTLOADER_SIZE` and other build options in `Makefile` and `config.h`. At least PJRC Teensy requires changing `BOOTLOADER_SIZE` to 512.
57 Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. Just `make` with `KEYMAP` option like:
59 $ make -f Makefile.<jp|pjrc|rn42> KEYMAP=(hasu|hhkb|spacefn|<name>)
61 You can omit `-f` option when you use `Makefile`. `Makefile` is used for **Pro2 and Pro**, `Makefile.jp` fits for **JP** model and `Makefile.rn42` supports Bluetooth module **RN-42**. `Makefile.pjrc` uses **PJRC** as output protocol instead of **LUFA**.
65 First, push reset button on board to start bootloader.
67 This command programs the controller with [dfu-programmer] if the tool is installed and configured properly.
69 $ make -f Makefile.<variant> KEYMAP=<name> dfu
71 Or you can also use [FLIP] command to program. Also the tool should be installed and configured properly. FLIP GUI application is also available.
73 $ make -f Makefile.<variant> KEYMAP=<name> flip
75 Use [Teensy Loader] if your controller is Teensy/Teensy++.
79 To define your own keymap create a file in the keymaps folder named `<name>.c` and see keymap document (you can find in top README.md) and existent keymap files.
83 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.

86 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.
90 See [this thread](http://geekhack.org/index.php?topic=57008.0).
