Sparkfun buttonpad SPI.


I just bought a few of these : Button Pad Controller SPI - WIG-09022 - SparkFun Electronics .

I'm having trouble interfacing it with arduino.
Sparkfun gives no example code, and all the code I can find is either incomplete or broken.

Has anybody here ever got it to work with arduino and would like to share code ?

Thanks a lot !

SparkFun has some good stuff, but their documentation is always pretty minimal or at least not in the tutorial mode, where you can learn how, not just what.

c.f., adafruit tutorials!
