Hey,
Did you put the .llb files from in the _express folder as described in the directions? If so, your next steps is to open a blank VI. When viewing the block diagram, right click and navigate from the functions palette to User Libraries > Express User Libraries > Palette Menu > EEG subVi. Drag this VI onto your diagram (1, or 19 lead). If you open the context help for this object, it will tell you what each terminal is for. I recommend for now to create controls for the terminals on the right (so you can set the patient state and the # samples to read from the Front Panel).
If using the 1 lead vi, you'll want to connect the EEG data output to a Waveform Chart input.
If using the 19 lead vi, you'll want to take the data from each EEG channel and connect it to a Build Array function. Take the single output of the Build Array function and connect that to a Waveform Chart input.
If you would like to know the Sampling Rate, you can right click on the EEG vi's samping rate terminal and create an indicator.
I hope this helps you get started!
