+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.
+ http://www.pjrc.com/teensy/loader.html
+
+
+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.
