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

Feature
-------
- Mouse Keys
- NKRO on USB
- Keymap Layers


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


Build for 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, USB_EXTRA_ENABLE, USB_NKRO_ENABLE
3. Build hex file.
    $ make
4. Program MCU.
    $  make program


Build for 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, USB_EXTRA_ENABLE, USB_NKRO_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.
