analog signal smoothing

SO obviously I am not sure how to do that, maybe you can shed some light on it. Once I acquire the data from my daq assistant, convert it to a 1d array of scalars ...????

Also, I am only using one channel of the daq, channel 0

Ok so I was able to get more data points by queueing the data, but now I want to be able to zero the reading, which I am trying to do with a shift register, but after it initially goes to zero, it reverts back to the original value

I think you need to get away from the express VIs.  Converting to and from the dynamic data type just adds unneeded complexity.  I've attached a simplified VI that runs a DAQmx task and saves the data to a text file.  Hopefully this will be a good starting point for you.

I'm not sure what you are talking about with "zero the reading".  Are you trying to remove the DC offset?

Yes, I am trying to remove the offset so I have a zero starting point. I was actually able to do it by negating the initial data in a case structure, then indexing that array from the shift register and adding the negated initial value to the current value. Thanks for all your help.
