Post a link to the device you bought.

This is the one I've got which is based on a MCP23017 I2C GPIO driver
http://www.modmypi.com/raspberry-pi/bre ... -board-kit
it's really easy to program that.

If you don't have the MCP23017 it's going to need 16 GPIOs from your RPi to drive it.

If it really is just the raw 8*8 led matrix it is going to be a bit of work driving it from the Pi.
It might be worth googling around for the max7219 chip, or 74HC595, to see what is commonly done with this type of part.
On ebay many 8*8 matrix are sold for a couple of quid as a kit including the max7219 chip, although some soldering is required.
I had a Sunfounder kit of bits, with just the 8*8 with it, to be used with the 74HC595s, but the max chips make things a lot easier, you don't have to worry about multiplexing. Here's the Sunfounder video:

plenty of wiring up, whereas the max kits just need 3 wires plus power and can easily be cascaded.
