then you have to select the positioning of your 8x8 led matrix and all other components according to your PCB...

Building the 8x8 Med Matrix

you can get instructions how to build an LED matrix on many pages on the internet, here is the process, by which i made it....

Making Connections

its the hardest part of building the hardware, and you must be careful about making the exact same connections as i made, otherwise the code wont work on it, i have uploaded an eagle's schematic file, with the diagram which shows the essential connections which are to be made EXACTLY the same way...
