If you give us a little bit more information on what device you're using, we could help a lot more.

SPI is extremely straight forward.  The Atmel controllers have a hardware SPI port which sends 8 bits at a time.  So, depending on how your device works, it could be as simple as sending 3 bytes using the SPI port.
