/******************************************************************
|
|
* 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.
|
|
* 1.9
|
|
* Kurt - Added detection and recovery from dropping from analog mode, plus
|
|
* integreated Chipkit (pic32mx...) support
|
|
