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.
-This firmware converts PS/2 keyboard protocol to 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.

+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.

-Demostration build
-------------------
-In this demo build, you can try several layouts,
-mouse keys and USB NKRO.
+Demonstration of Features
+-------------------------
+In default configuration, you can try several keymaps, mousekeys and USB NKRO.
+Use following magic key combinations to enable some features.
-Special keys:
- Magic+0: Qwerty with mouse keys(default)
- Magic+1: Qwerty
+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
+ Magic+Esc: sends Power Event(Power button)
+
where Magic=(LShift+RShift) or (LControl+RShift)
-Keybinds:
- Fn0+(hjkl): Mouse key move(vi cursor)
+Fn layer function:
+ Fn0+(hjkl): Mousekey move(vi cursor like)
Fn0+(yuio): Mouse wheel(left,down,up,right)
- Fn0+space: Mouse button1
- Fn0+(mnb): Mouse buttons(1,2,3)
+ 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)
+ Fn1+(hjkl): Cursor move(vi cursor like)
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

-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.

+ 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.
