I wanted to add some features like vi cursor and mouse keys to my 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 in geekhack.org for details.
- Bluetooth module RN-42 is supported.(2015/01)
- Customizable keymap
- More keymap layers(more Fn keys)
- Mouse keys
- USB NKRO
- Bluetooth(RN-42)
See README of tmk_keyboard for more.
- 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
- Void your warranty
- Lose USB hub function of Pro2
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.
See doc/HHKB.txt and files under doc/ for internal of HHKB and this controller.
See this document and this first.
Build options and firmware settings are available in Makefile and config.h or config_rn42.h.
To define your own keymap create file named keymap_<name>.c and see keymap document and existent keymap files.
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.<variant> KEYMAP=<name> clean
$ make -f Makefile.<variant> KEYMAP=<name>
Makefile can be used for Pro2 and Pro USB controller, Makefile.jp for JP, Makefile.rn42 for Pro2 Bluetooth and Makefile.rn42.jp for JP Bluetooth.
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
Preassmbled controller is available from here.
You can find design files of the controller at Keyboard Controller Board for HHKB(KiCad project).
