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
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/6KRO.(Not tested on Mac.)
You can tolggles NKRO feature.
Keymap customization
You can customize keymaps easily by editing source code.
You can customize keymaps easily by editing source code. See keymap.c.
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.
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
3. program Teensy.
Just type 'make' in a terminal.
3. program with Teensy Loader.
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.
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)

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.

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.
