Read from a csv and output to DAQ Assistant

[opampmaster]

Hi,

I am trying to generate an arbitrary noise file that I have generated into a CSV file. I am trying to output that signal to a DAQ Assistant that is setup to the voltage output of a D to A device(NI9263).

I am not able to read the CSV file with the read from spreadsheet block and I need help.

Any help would be appreciated.

Thanks in advance,

Daniel Han

Unfortunately we could not imagine how the CSV file looks like and why your code does not work with that CSV file

This is my CSV file. I dont know how to connect this and include a dt interval so it can become a signal for my DAQ assistant

Your csv file has 1 row and more than 1 million columns.

Nevertheless, the read function worked when given a comma as the correct delimiter instead of the default tab.

Thank you!

That worked got me a ton of progress.

But it is still not sending the voltages to the DAQ. How would it know the sample rate?

Thanks again, I am very new to all of this and I am still learning

Since the data files don't include any timing information, it'll have to be up to *you* to determine a sensible sample rate and set up the DAQ task accordingly.  I never use the DAQ Assistant, so I can't really speak to the detailed steps involved.  (I'd recommend you try to start using regular DAQmx functions too.  See the shipping examples, right-click a DAQ Assistant and tell it to convert to DAQmx code, and read through this article.)
