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 for details.

## 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.

## HHKB Internals
|
|
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](../../tmk_core/doc/build.md) and [this](https://github.com/tmk/tmk_keyboard/wiki#build-firmware) first.
|
|
|
|
### Configuration
|
|
Build options and firmware settings are available in `Makefile` and `config.h` or `config_rn42.h`.
|
|
|
|
|
|
### Keymap
|
|
To define your own keymap create file named `keymap_<name>.c` and see [keymap document](../../tmk_core/doc/keymap.md) and existent keymap files.
|
|
|
|
|
|
### 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.<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.
|
|
|
|
|
|
### 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
|
|
|
|
|
|
|
|
## Hardware
