I just have some basic skills regarding to the labview. i download the program to help me to build my own eeg signal collecting program. but I dont really understand how the two programs are built and how to get those two to work. Would some please explain this to me?

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!
