** Mostly rewritten Paul Stoffregen <paul@pjrc.com> 2010, 2011
** Modified for use beginning with Arduino 13 by L. Abraham Smith, <n3bah@microcompdesign.com> *
** Modified for easy interrup pin assignement on method begin(datapin,irq_pin). Cuningan <cuninganreset@gmail.com> **
** Custom version modifed by Tomasz Rękawek <tomek@rekawek.eu> to only provide scancodes.
for more information you can read the original wiki in arduino.cc
at http://www.arduino.cc/playground/Main/PS2Keyboard
or http://www.pjrc.com/teensy/td_libs_PS2Keyboard.html
Version 2.4 (March 2013)
- Support Teensy 3.0, Arduino Due, Arduino Leonardo & other boards
- French keyboard layout, David Chochoi, tchoyyfr at yahoo dot fr
Version 2.3 (October 2011)
- Minor bugs fixed
Version 2.2 (August 2011)
- Support non-US keyboards - thanks to Rainer Bruch for a German keyboard :)
Version 2.1 (May 2011)
- timeout to recover from misaligned input
- compatibility with Arduino "new-extension" branch
- TODO: send function, proposed by Scott Penrose, scooterda at me dot com
Version 2.0 (June 2010)
- Buffering added, many scan codes can be captured without data loss
if your sketch is busy doing other work
- Shift keys supported, completely rewritten scan code to ascii
- Slow linear search replaced with fast indexed table lookups
- Support for Teensy, Arduino Mega, and Sanguino added
