PS/2 to USB keyboard converter
==============================
This firmware converts PS/2 keyboard protocol to USB.
Demostration build
------------------
In this demo build, you can try several layouts,
mouse keys and USB NKRO.
Special keys:
Magic+0: Qwerty with mouse keys(default)
Magic+1: Qwerty
Magic+2: Colemak
Magic+3: Dvorak
Magic+4: Workman
Magic+N: toggles NKRO/6KRO(6KRO by default)
Magic+Esc: sends Power Event
where Magic=(LShift+RShift) or (LControl+RShift)
Keybinds:
Fn0+(hjkl): Mouse key move(vi cursor)
Fn0+(yuio): Mouse wheel(left,down,up,right)
Fn0+space: Mouse button1
Fn0+(mnb): Mouse buttons(1,2,3)
Fn0+(zxc): Media control(Volup, Voldown, Mute)
Fn1+(hjkl): Cursor move(vi cursor)
Fn1+(nm,.): Cursor move(Home,PageDown,PageUp,End)
Fn2+(esdf): Mouse key move(invert T cursor)
Fn2+(qwrt): Mouse wheel(left,down,up,right)
Fn2+space: Mouse button1
Fn2+(,./): Media control(Volup, Voldown, Mute)
where Fn0=;, Fn1=/, Fn2=a
Features
--------
Mouse keys
You can emulates mouse move and button click using keyboard.
System/Media control
You can sends Power event, Volume down/up and Mute.
USB NKRO(actually 120KRO+8Modifiers)
You can tolggles NKRO/6KRO.(Not tested on Mac.)
Keymap customization
You can customize keymaps easily by editing source code.
Build
-----
0. Connect PS/2 keyboard to Teensy by 4 lines(Vcc, GND, Data, Clock).
1. Define following macros for PS/2 connection in config.h:
PS2_DATA_PORT
PS2_DATA_PIN
PS2_DATA_DDR
PS2_DATA_BIT
PS2_CLOCK_PORT
PS2_CLOCK_PIN
PS2_CLOCK_DDR
PS2_CLOCK_BIT
2. Edit Makefile for build options and MCU setting.
2. make
3. program Teensy.

Keymap
------
You can change a keymap by editing code of keymap.c like following.
How to define the keymap is probably obvious. You can find key
symbols in usb_keycodes.h.
If you want to define more than one keymap, see hhkb/keymap.c and
macway/keymap.c as examples. To define keymap(layer) switching may
needs a bit of your effort at this time.
