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.
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.
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
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)

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.
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.
