I started with shift registers and 7-segment displays with an arduino board., pretty straight forward and hooks up via usb only just started myself. Got some nice help from here also but you need to read this so your post is able to be answered How to use this forum - please read - Website and Forum - Arduino Forum
From what i saw looking at the link you gave there is tons of info and you have to use a library also i think, was way too much info to read all.
- are you using the microcontroller on the board or a separate one?
2.Have you got the display to light up or even work?
So how are you wiring it up and what code are you trying.
You need to post both for help.
That device can be interfaced in several ways.
