PS/2 to USB keyboard converter
==============================
This firmware converts PS/2 keyboard protocol to USB and for now supports only Scan Code Set 2.


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 feature.

Keymap customization
    You can customize keymaps easily by editing source code. See keymap.c.


Build Converter
---------------
0. Connect PS/2 keyboard into Teensy with 4 lines(Vcc, GND, Data, Clock).
   By default Clock is on PF0 and Data on PF1.
   You can change this pin configuration by editing config_pjrc.h.
   In this photo Vcc is yellow, GND is green, Data is red and Clock is black.

Build Frimware
--------------
1. Edit Makefile for build options and MCU setting.
   Use 'atmega32u4' for Teensy 2.0 or 'at90usb1286' for Teensy++ 2.0.
2. make
   Just type 'make' in a terminal.
3. program with Teensy Loader.

Demonstration of Features
-------------------------
In default configuration, you can try several keymaps, mousekeys and USB NKRO.
Use following magic key combinations to enable some features.

keymaps and NKRO:
    Magic+0:    Qwerty with mousekeys(default)
    Magic+1:    Qwerty without mousekeys
    Magic+2:    Colemak
    Magic+3:    Dvorak
    Magic+4:    Workman
    Magic+N:    toggles NKRO/6KRO(6KRO by default)
    Magic+Esc:  sends Power Event(Power button)

    where Magic=(LShift+RShift) or (LControl+RShift)

Fn layer function:
    Fn0+(hjkl): Mousekey move(vi cursor like)
    Fn0+(yuio): Mouse wheel(left,down,up,right)
    Fn0+space:  Mouse left button
    Fn0+(mnb):  Mouse buttons(m=left, n=right, b=middle)
    Fn0+(zxc):  Media control(Volup, Voldown, Mute)
    Fn1+(hjkl): Cursor move(vi cursor like)
    Fn1+(nm,.): Cursor move(Home,PageDown,PageUp,End)

    where Fn0=;, Fn1=/


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.
To define keymap layer switching may needs a bit of your effort at this time.
