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**, **Professional** 2, **JP** and **Type-S**.
|
|
|
|
See [this thread][AltController] in geekhack.org.

## Update
|
|
* Bluetooth module RN-42 is supported.(2015/01)
|
|
* V-USB and iWRAP are no longer supported now, but still it'll works with a little fix. See not_supported directory.(2015/01)
|
|
|
|
|
|
##Features
|
|
* Customizable keymap
|
|
* More keymap layers(more Fn keys)
|
|
* Mouse keys
|
|
* USB NKRO
|
|
* Bluetooth(RN-42)
|
|

###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 behavior 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
|
|
If your target is **HHKB JP** you need to set `HHKB_JP` build option in `Makefile` or use `Makefile.jp` instead of `Makefile`.
|
|
|
|
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.
|
|
|
|
### Build
|
|
Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. Just `make` with `KEYMAP` option like:
|
|
|
|
$ make -f Makefile.<jp|pjrc|rn42> KEYMAP=(hasu|hhkb|spacefn|<name>)
|
|
|
|
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**.
|
|
|
|
|
|
### Program
|
|
First, push reset button on board to start bootloader.
|
|
|
|
This command programs the controller with [dfu-programmer] if the tool is installed and configured properly.
|
|
|
|
$ make -f Makefile.<variant> KEYMAP=<name> dfu
|
|
|
|
Or you can also use [FLIP] command to program. Also the tool should be installed and configured properly. FLIP GUI application is also available.
|
|
|
|
$ make -f Makefile.<variant> KEYMAP=<name> flip
|
|
|
|
Use [Teensy Loader] if your controller is Teensy/Teensy++.
|
|
|
|
|
|
##Keymap
|
|
To define your own keymap create file named `keymap_<name>.c` and see [keymap document](../../doc/keymap.md) and existent keymap files.
|
|
|
|
|
|
##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 cheaper option for DIY.
|
|
|
|
###1. TMK Alt Controller Board
|
|
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.
|
|
|
|
|
|
###2. PJRC Teensy
|
|
See [this thread](http://geekhack.org/index.php?topic=57008.0).
