@ -2,128 +2,144 @@ 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. For this purpose I used PJRC [Teensy++][Teensy] as alternative controller.
controller with programmable one. This controller can work with HHKB Professional and Professional 2 model.
See [this thread][AltController] in geekhack.org.
[HHKB]: http://www.pfu.fujitsu.com/hhkeyboard/
[AltController]: http://geekhack.org/index.php?topic=12047.0
[Teensy]: http://www.pjrc.com/teensy/
My keyboard firmware source tree is here: http://github.com/tmk/tmk_keyboard
See directory keyboard/hhkb to build firmware for HHKB.
##Features
* Customizable keymap
* More keymap layers(more Fn keys)
* Mouse keys
* USB NKRO
See README of [tmk_keyboard] for more.
[tmk_keyboard]: http://github.com/tmk/tmk_keyboard
###Pros
* No risk: Everything is all reversible
* Without PCB trace cutting, case mod or any destructives
* Can keep original controller intact
* Can change all HHKB behaviour as you like
###Cons
* Void your warranty
* Lose USB hub function in case of Pro2
* Lose USB hub function of Pro2
##DISCLAIMER
I'm not a professional of electronics or MCU programming. This may damage your HHKB.
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
You can choose some combination of hardware and USB protocol stack([LUFA], [PJRC]).
### Install Tools
See [this document](../../doc/build.md).
### TMK Alt Controller Board
$ make -f Makefile.tmk
This programs the controller with [dfu-programmer] if the tool is intalled and configured properly.
$ make -f Makefile.tmk dfu
Push reset button and program with [FLIP]. The tool should be intalled and configured properly.
$ make -f Makefile.tmk flip
Or you can also program with FLIP GUI.
[dfu-programmer]: http://dfu-programmer.sourceforge.net/
[FLIP]: http://www.atmel.com/tools/FLIP.aspx
##Build Firmware
You can choose some combination of MCU and USB protocol stack.
### PJRC Teensy++
Build with [LUFA] USB stack:
### Teensy++(AVR USB family) with [LUFA]
0. Edit **matrix.c** to use your pin configuration. See doc/HHKB.txt for detail.
$ make -f Makefile.lufa
1. Edit **keymap.c** to use your favoirte keymap.
or with [PJRC] USB stack:
2. Edit **Makefile** if you want to use other `MCU` than Teensy++ 2.0.
$ make -f Makefile.pjrc
3. Build firmware binary file:
`$ make -f Makefile.lufa`
Push reset button and program with [Teensy Loader(command line)]. The tool should be intalled and configured properly.
4. Program MCU with PJRC [Teensy Loader] tool. If you install command line version of the loader just run:
`$ make -f Makefile.lufa teensy`
$ make -f Makefile.lufa teensy
$ make -f Makefile.pjrc teensy
Or you can also program with [Teensy Loader(GUI)].
[LUFA]: http://www.fourwalledcubicle.com/LUFA.php
[Teensy Loader]: http://www.pjrc.com/teensy/loader.html
[PJRC]: http://www.pjrc.com/teensy/usb_keyboard.html
[Teensy Loader(command line)]: http://www.pjrc.com/teensy/loader_cli.html
[Teensy Loader(GUI)]: http://www.pjrc.com/teensy/loader.html
###AVR Mega with [V-USB]
Follow below if you want to use AVR with V-USB as .
Build:
$ make -f Makefile.vusb
0. Edit **matrix.c** to use your pin configuration. See doc/HHKB.txt for detail.
Program [USBaspLoader] on MCU with AVR programmer like [AVRISPmkII] and tool like [avrdude].
1. Edit **keymap.c** to use your favoirte keymap.
You can programs with [avrdude] once you have programmed [USBaspLoader] on MCU.
$ make -f Makefile.vusb program
2. Edit **usbconfig.h** to configure V-USB options.
3. Edit **Makefile.vusb** to define `MCU` and `F_CPU`.
4. Build firmware binary file:
`$ make -f Makefile.vusb`
5. Program MCU with AVR programmer like AVRISPmkII. If you already have [USBaspLoader] on MCU just run:
`$ make -f Makefile.vusb program`
[V-USB]: http://www.obdev.at/products/vusb/index.html
[USBaspLoader]: http://www.obdev.at/products/vusb/usbasploader.html
[AVRISPmkII]: http://www.atmel.com/tools/AVRISPMKII.aspx
[avrdude]: http://www.nongnu.org/avrdude/
###How to Customize Keymap
Later...
See **keymap.c**.
##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.
###Teensy++ installation
Angled USB mini B adapter is used to install Teensy++ laterally.

###1. TMK Alt Controller Board
TMK designed [Keyboard Controller Board for HHKB Pro2(KiCad project)](https://github.com/tmk/HHKB_controller).
