Keyboard Firmware
=================
2010/08/23 noname


VERSION
-------
0.1     2010/08/23
        implemented for macway modified.
        It works as normal keyboard now.


TODO
----
modulization
    clean source
debouncing
anti-ghost
keymap layer
    key combination switch
    toggle siwtch
    HHKB like cursor etc.
setting menu(wizard)
    debug console
    keymap setting
    matrix display
HHKB support
Trackpoint(PS/2) support
    Thinkpad keyboard support


target board
------------
Teensy 2.0
