7 Segment Display using SPI

Thanks guys. As far as the wiring goes I am all set. I have the three displays wires all on the same bus except for the Slave "CSN" wire which is on a different pin on the Arduino. For me, that was the easy part.

The code on the other hand is what I am trying to learn how to do. I was looking for more example code to help me figure this SPI thing out.

@Ran, I was wondering if Slaveselect in Busaboi's code was a special function from the library, so you cleared that up for me. And yes, I need all three displays to simultaneously display constantly updating information.

Also, Busaboi doesn't call up the SPI.h library that I have seen. Is it unnecessary to do so?
