I have problems to understand how to connect a MAX5481EUD+ Digital-Potentiometer.

It looks like you can control it in two ways?
So my problem is what to do with SPI and DIN.

Hello, I had the same problem when I started working with this part. I created a module that uses both SPI and the manual push-button options. Look here for a reference for my project, it shows how to hookup both ways. If you use the manual method(NON SPI, pushbutton) be careful of the de-bounce!! I learned the hard way. I ended up using an RC based approach I got from another forum. If i do less the 3 clicks a second it works ok, more then that it will DOUBLE the value.
