PS2 Controller Library for the Raspberry Pi

This project is built from bits and pieces I've found on the Internet, including, but not limited to Bill Porter madsci1016/Arduino-PS2X c-herring/PiPS2

For some reason, I couldn't get the PiPS2 library to work with my Chinese knockoff PS2 controller, so I sat down and hacked it beyond recognition. I've probably thrown a dozen babies out with the bath water, but now

IT WORKS FOR ME

To compile, you need the wiringPi library, and if you want to run the curstst program, you'll need the curses library. I've included two shell scripts for your convenience.

Usage

There's a messy way and a clean way.

The messy way

Create spaghetti code
LOOP
	Read PS2 Controller
	See if this button is pressed
	See if that button is pressed
	Clutter up the code with more of these
END LOOP

For an example, see the file messy.cpp

The clean way

Register all your functions as actions
LOOP
    Read PS2 Controller and dispatch actions
END

For an example, see the file clean.cpp

setXAction(xaction, user_data)

Register a function void xaction(int pressure, void *user_data) to be called when the X button is pressed. The pointer user_data can point to anything.

TODO

See if I can get pressure mode and native mode to work. Find a better way to ensure valid data
