t.m.k. Keyboard Firmware
========================
http://github.com/tmk/tmk_keyboard

This is keyboard firmware for PFU HHKB style keyboard and Teensy/Teensy++ 2.0.
OS see this as composite device which has keyboard and mouse.

The project is heavily based on PJRC USB Keyboard/Mouse Example and
owes a debt to preceding keyboard firmware projects.


Version
-------
0.1     2010/08/23
        It works as normal keyboard.
        It is for modified Macway keyboard(TP-999KB-E).

1.0     2010/10/02
        keyboard has mouse key now.
        keyboard with layers.(see keymap.c)
            FN_1(right cmd):
                vi style layer
            FN_2(next to right shift):
                HHKB style layer
            FN_3(left bottom):

1.1     2010/10/08
        Matrix wiring changed for casing.
        (and my Teensy PD3 seems to be latchuped and unusable. :<)

1.2     2010/10/13
        HHKB support
        horizontal mouse wheel support
        change keymaps


Build
-----
Compiling sources need AVR GCC, AVR Libc and GNU make.(You can use WinAVR on Windows.)

$ cd <target> (hhkb or macway)
$ make


Debuging
--------
Debug print is on if 4 keys are pressed during booting. 
Use PJRC's hid_listen.exe to see debug messages.

TODO & ideas
------------
licensing notes(GPL)
    I think GPL is not infringement of PJRC license.
souce code cleaning
sleep&wakeup
debouncing logic
    will be coded when bouncing occurs.
    bouncing doesnt occur on my ALPS switch so far.
    scan rate is too slow?(to be measure)
layer switching
    time before switching
    timeout when not used during specific time

Trackpoint(PS/2)
    receive PS/2 signal from TrackPoint
    send USB HID report
Thinkpad keyboard support
    turn keyboard to USB keyboard/mouse composite device
setting menu(configure without changing firmware)
    console for display
    keymap/layer setting
    mouse speed/acceleration
    matrix display
PS/2 keyboard mode
    with USB to PS/2 dumb adapter(possible?)
AT90USBKEY support
    and other AVR USB boards

DONE:
support for HHKB pro matrix signal
    exchange controller board with teensy
    2010/10/11
