7 Segment Display using SPI

Fred, try changing the spi bus freq by sending (<<SSPR0) instead of (1<<SPR1). This will divide by 16 and not 64.

Also, check these pins (ref Arduino.cc SPI library page)

pin 13 SCK SPI clock
pin 12 MISO SPI master in, slave out
pin 11 MOSI SPI master out, slave in
pin 10 SS SPI slave select

Hope this helps!
