Alternative Controller for HHKB
===============================

Feature
-------
- Mouse Keys
- NKRO on USB(PJRC Tennsy only)
- Keymap Layers


Customize Keymap
----------------
see keymap.c.



Build
=====
PJRC Teensy
-----------
0. Edit matrix.c.
    adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
1. Define macros in config_pjrc.h.(Optional)
    VENDOR_ID, PRODUCT_ID and string descriptor.
    IS_COMMAND
2. Edit Makefile for MCU setting and build options.
    MCU, F_CPU
    MOUSEKEY_ENABLE, EXTRAKEY_ENABLE, NKRO_ENABLE
3. Build hex file.
    $ make -f Makefile.pjrc
4. Program MCU.
    $  make -f Makefile.pjrc program


V-USB
-----
0. Edit matrix.c and usbconfig.h.
    adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
    define macros for V-USB in usbconfig.h.
1. Define macros in config_vusb.h.(Optional)
    IS_COMMAND
2. Edit Makefile.vusb for MCU setting and build options.
    MCU, F_CPU
    MOUSEKEY_ENABLE, EXTRAKEY_ENABLE
3. Build hex file.
    $ make -f Makefile.vusb
4. Program MCU.
    $  make -f Makefile.vusb program

    Using a bootloader to program for convenience is recommended.
    Once program this V-USB bootloader at first, you can program MCU without
    extra programmer. You should have reset switch to start up as bootloader
    mode in this case.

iWRAP
-----
0. Edit matrix.c and usbconfig.h.
    adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
    define macros for V-USB in usbconfig.h.
1. Define macros in config_iwrap.h.(Optional)
    IS_COMMAND
2. Edit Makefile.iwrap for MCU setting and build options.
    MCU, F_CPU
    MOUSEKEY_ENABLE, EXTRAKEY_ENABLE
3. Build hex file.
    $ make -f Makefile.iwrap
4. Program MCU.
    $  make -f Makefile.iwrap program
