- Alternative Controller for HHKB Pro
- ===================================
- 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. This controller can work with HHKB Professional and Professional 2 model.
-
- See [this thread][AltController] in geekhack.org.

- [AltController]: http://geekhack.org/index.php?topic=12047.0
-
-
- ##Features
- * Customizable keymap
- * More keymap layers(more Fn keys)
- * Mouse keys
- * USB NKRO
-
- See README of [tmk_keyboard] for more.

-
- ###Pros
- * No risks: Everything is all reversible
- * No need for PCB trace patching, case cutting or any other destructive mod
- * Can keep original controller intact
- * Can change all HHKB behaviour as you like
-
- ###Cons
- * Void your warranty
- * Lose USB hub function of Pro2
-
- ##DISCLAIMER
- I'm not a professional of electronics nor MCU programming. This may damage your HHKB.
- And my English writing is poor, I'm not sure I can convey my notions accurately.
-
-
- ##Documents
- See [doc/HHKB.txt](doc/HHKB.txt) and files under [doc/](doc/) for internal of HHKB and this controller.
-
-
- ##Build Firmware & Program
- See [this document](../../doc/build.md) first.
-
- ### Configuration
- Set `MCU`, `BOOTLOADER_SIZE` and other build options in `Makefile` and `config.h`.
-
- ### Build
- Just run make after intall tools.
-
- $ make
-
- Use `Makefile.pjrc` if you want to use PJRC stack instead of LUFA.(LUFA is recommended.)
-
- $ make -f Makefile.pjrc
-
- Use `Makefile.vusb` for [V-USB] controller.(not supported actively any more.)
- $ make -f Makefile.vusb
-
- ### Program
- First, push reset button on board to start bootloader.
-
- This command programs the controller with [dfu-programmer] if the tool is intalled and configured properly.
-
- $ make dfu
-
- Or you can also use [FLIP] command to program. Also the tool should be intalled and configured properly. FLIP GUI app is also available.
-
- $ make flip
-
- Use [Teensy Loader] if your controller is Teensy/Teensy++.
-
-
- ##How to Customize
- See [tmk_keyboard] documents.
-
-
- ##Hardware
- 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 cheapear option for DIY.
-
- ###1. TMK Alt Controller Board
- TMK designed [Keyboard Controller Board for HHKB Pro2(KiCad project)](https://github.com/tmk/HHKB_controller).
- See [this post](http://geekhack.org/index.php?topic=12047.msg948923#msg948923).
