Are you wanting to capture data real-time? VisualAnalog does have the capability to save up to 64k samples to a text file from the Samples canvas. On the graph window, you can just select the Save icon.
Thanks for the reply. At some point soon I do have the need to process in real-time. This is for an industrial imaging application and I'd like to push the data into MATLAB to test post-processing/mapping algorithms.
