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

* 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
|
|
Set `MCU`, `BOOTLOADER_SIZE` and other build options in `Makefile` and `config.h`.
|
|
|
|
### 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 KEYMAP=[hasu|hhkb|spacefn|<name>]
|
|
|
|
|
|
### 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 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 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(you can find in top README.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.
