There are many devices successfully using PICs to decode DMX but I think you need to read up more on the subject.

The only places a DMX address exists is within the controllers memory and as a setting on the DIP switches of the dimmer pack/lighting fixture.

The data travelling along the DMX cable does not contain ANY explicit address information, it is merely a stream of bytes indicating the levels for all the channels starting at the first channel. You have to count the number of bytes being received and act upon the byte(s) that correspond to the address your receiver is set to.
