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.
Keymap
------
You can change a keymap by editing code of keymap.c like following.

PS/2 to USB keyboard converter with V-USB
=========================================
2011/02/07
NOT COMPLETED
development was suspended.
TODO:
PS/2 library: losts data from keyboard occasionally,
should use interrupt thoroughly for communication.
Code cleaning: merge code changed here to other subprojects and common modules.

* PS/2 Scan Code Set 2: Exceptional Handling
*
* There are several keys to be handled exceptionally.
* The scan code for these keys are varied or prefix/postfix'd
* depending on modifier key state.

* Insert, Delete, Home, End, PageUp, PageDown, Up, Down, Right, Left:
* Num Lock: off
* modifiers | make | break
* ----------+---------------------------+----------------------
* Ohter | <make> | <break>
* LShift | E0 F0 12 <make> | <break> E0 12
* RShift | E0 F0 59 <make> | <break> E0 59
* L+RShift | E0 F0 12 E0 F0 59 <make> | <break> E0 59 E0 12
*
* Num Lock: on
* modifiers | make | break
* ----------+---------------------------+----------------------
* Other | E0 12 <make> | <break> E0 F0 12
* Shift'd | <make> | <break>
*
* Handling: ignore these prefix/postfix codes
*
*
* Keypad-/:
* modifiers | make | break
* ----------+---------------------------+----------------------
* Ohter | <make> | <break>
* LShift | E0 F0 12 <make> | <break> E0 12
* RShift | E0 F0 59 <make> | <break> E0 59
* L+RShift | E0 F0 12 E0 F0 59 <make> | <break> E0 59 E0 12
*
* Handling: ignore these prefix/postfix codes
*
*
* PrintScreen:
* With hoding down modifiers, the scan code is sent as following:
*
* modifiers | make | break
* ----------+--------------+-----------------------------------
* Other | E0 12 E0 7C | E0 F0 7C E0 F0 12
* Shift'd | E0 7C | E0 F0 7C
* Control'd | E0 7C | E0 F0 7C
* Alt'd | 84 | F0 84
*
* Handling: ignore prefix/postfix codes and treat both scan code
* E0 7C and 84 as PrintScreen.
*
* Pause:
* With hoding down modifiers, the scan code is sent as following:
*
* modifiers | make(no break code)
* ----------+--------------------------------------------------
* no mods | E1 14 77 E1 F0 14 F0 77
* Control'd | E0 7E E0 F0 7E
*
* Handling: treat these two code sequence as Pause
