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 and **Type-S**.
7 See [this thread][AltController] in geekhack.org.

15 * More keymap layers(more Fn keys)
19 See README of [tmk_keyboard] for more.

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
31 * Lose USB hub function of Pro2
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.
39 See [doc/HHKB.txt](doc/HHKB.txt) and files under [doc/](doc/) for internal of HHKB and this controller.
42 ##Build Firmware & Program
43 See [this document](../../doc/build.md) first.
46 Set `MCU`, `BOOTLOADER_SIZE` and other build options in `Makefile` and `config.h`.
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:
51 $ make KEYMAP=[hasu|hhkb|spacefn|<name>]
55 First, push reset button on board to start bootloader.
57 This command programs the controller with [dfu-programmer] if the tool is installed and configured properly.
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.
65 Use [Teensy Loader] if your controller is Teensy/Teensy++.
69 To define your own keymap create file named `keymap_<name>.c` and see keymap document(you can find in top README.md) and existent keymap files.
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.
