Can some explain this diagram connections

[proaudiosoft]

can someone explain this diagram to me. its a pic microcontroller connection to a 360 controller. I understand the 3 volts going to the pic, but why the resistors and 3 volts past the switches? is it a workable circuit?

The two 2.2k resistors going to 3.3V are called pull-ups. They keep those lines at a high logic state until something else pulls them low. The remaining two series resistors limit current, and are likely for protection of the PIC chip.

I don't know if it's workable. I don't know what the rest looks like, nor what a 360 controller is. But fundamentally it looks fine.

Thanks corey, I appreciate you time. since your input I am def goint to give this a try.
