===================================
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**.

### Configuration
Set `MCU`, `BOOTLOADER_SIZE` and other build options in `Makefile` and `config.h`.
Set `MCU`, `BOOTLOADER_SIZE` and other build options in `Makefile` and `config.h`. If your target is **HHKB JP** you need to set `HHKB_JP` build option in `Makefile`.
### 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:

##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
TMK designed [Keyboard Controller Board for HHKB Pro2(KiCad project)](https://github.com/tmk/HHKB_controller).
See [this post](http://geekhack.org/index.php?topic=12047.msg948923#msg948923).
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.

Space bar locate at ROW:3 COL:7. A key is selected by HC4051(C,B,A) and LS145(C,B,A).
Key state can be read on TP1684(4/KEY) while asserting low on LS145(D).
Usage of TP1684(5) is not clear. Controller seemed to output previous key state on this line.
However key state can be read without using this signal.

Kitten Paw controller firmware
======================
Custom controller for the Costar Majestouch keyboard designed by bpiphany.
*Note that this is not the official firmware*
Build
-----
Move to this directory then just run `make` like:
$ make -f Makefile.lufa
At the moment only the LUFA stack is supported.
Bootloader
---------
To enter bootloader by hardware use a magnet above the controller before connecting the usb cable.
It is still possible to use Boot Magic and Command (LSFT+RSFT+PAUS) to access the bootloader though.

Lightpad keypad firmware
======================
Korean custom keypad designed by Duck.
*Note that this is not the official firmware*
Supported models
----------------
All pcb options are supported.
Build
-----
Move to this directory then just run `make` like:
$ make -f Makefile.lufa
Bootloader
---------
The PCB is hardwired to run the bootloader if the key at the `top left` position is held down when connecting the keyboard.
It is still possible to use Boot Magic and Command to access the bootloader though.
