lewkw,
There are many great examples that get installed for the 6552 when the NI-HSDIO driver is installed. If you plan on using this hardware in LabVIEW the examples can be found in the NI Example Finder under Hardware Input and Output>>Modular Instruments>>NI-HSDIO. You may want to look at the Dynamic examples depending on whether you need hardware timing or not. These VIs allow you to specify the logic family to use as well as the pattern that you would like to write out using the 6552. I hope this helps!
