+PS/2 to USB keyboard converter
+==============================
+This firmware converts PS/2 keyboard protocol to USB and for now supports only Scan Code Set 2.
+This will works on USB AVR(ATMega32U4, AT90USB) or V-USB.
+
+
+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.
+
+
+PS/2 signal handling implementations
+------------------------------------
+Following three methods are used to implement PS/2 signal handling.
+a. Simple and stupid wait & read loop(intensive use of cycles)
+    This is implemented with (expected) portable C code for reference. See ps2.c.
+b. Interrupt driven
+    See ps2_intr.c
+c. Using USART hardware module(no cycle needed)
+    This uses AVR USART function to recevie PS/2 signal and be used in V-USB converter.
+    See ps2_usart.c.
+
+
+Build Converter
+---------------
+Connect PS/2 keyboard into Teensy with 4 lines(Vcc, GND, Data, Clock).
+For a. Simple and stupid and b. Interrupt implementaion:
+    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.
+    http://img17.imageshack.us/img17/7243/201101181933.jpg
+For c. USART implementation:
+    In case of Teensny(ATMega32u4) CLock is on PD5 and Data on PD2.
+
+
+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.
+    Use '-f Makefile.pjrc_intr' option to use b. Interrupt.
+    Use '-f Makefile.pjrc_usart' option to use c. USART.
+    Use '-f Makefile.vusb' option to build V-USB converter.
+3. program with Teensy Loader.
+    http://www.pjrc.com/teensy/loader.html
+
+
+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.

+V-USB Support
+=============
+You can also use this converter on ATmega(168/328) with V-USB instead of Teensy.
+The converter on V-USB lacks some features for now: USB NKRO and System/Media control.
+
+To build a firmware use Makefile.vusb instead of Makefile.
