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 for Teensy
----------------
0. Connect PS/2 keyboard to Teensy by 4 lines(Vcc, GND, Data, Clock).
1. Define following macros for PS/2 connection in config_pjrc.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.
   http://www.pjrc.com/teensy/loader.html


Build for V-USB
---------------
0. Build V-USB controller board and connect PS/2 keyboard.
1. Define macros in config_vusb.h if needed.
2. Edit Makefile.vusb for build options and MCU setting.
3. make -f Makefile.vusb
4. program your V-USB controller.

X1:     Crystal 20MHz(16MHz/12MHz)


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.
