/******************************************************************
* Super amazing PS2 controller Arduino Library v1.8
* details and example sketch:
* http://www.billporter.info/?p=240
*
* Original code by Shutter on Arduino Forums
*
* Revamped, made into lib by and supporting continued development:
* Bill Porter
* www.billporter.info
*
* Contributers:
* Eric Wetzel (thewetzel@gmail.com)
* Kurt Eckhardt
*
* Lib version history
* 0.1 made into library, added analog stick support.
* 0.2 fixed config_gamepad miss-spelling
* added new functions:
* NewButtonState();
* NewButtonState(unsigned int);
* ButtonPressed(unsigned int);
* ButtonReleased(unsigned int);
* removed 'PS' from begining of ever function
* 1.0 found and fixed bug that wasn't configuring controller
* added ability to define pins
* added time checking to reconfigure controller if not polled enough
* Analog sticks and pressures all through 'ps2x.Analog()' function
* added:
* enableRumble();
* enablePressures();
* 1.1
* added some debug stuff for end user. Reports if no controller found
* added auto-increasing sentence delay to see if it helps compatibility.
* 1.2
* found bad math by Shutter for original clock. Was running at 50kHz, not the required 500kHz.
* fixed some of the debug reporting.
* 1.3
* Changed clock back to 50kHz. CuriousInventor says it's suppose to be 500kHz, but doesn't seem to work for everybody.
* 1.4
* Removed redundant functions.
* Fixed mode check to include two other possible modes the controller could be in.
* Added debug code enabled by compiler directives. See below to enable debug mode.
* Added button definitions for shapes as well as colors.
* 1.41
* Some simple bug fixes
* Added Keywords.txt file
* 1.5
* Added proper Guitar Hero compatibility
* Fixed issue with DEBUG mode, had to send serial at once instead of in bits
* 1.6
* Changed config_gamepad() call to include rumble and pressures options
* This was to fix controllers that will only go into config mode once
* Old methods should still work for backwards compatibility
* 1.7
* Integrated Kurt's fixes for the interrupts messing with servo signals
* Reorganized directory so examples show up in Arduino IDE menu
* 1.8
* Added Arduino 1.0 compatibility.
