How do I timestamps continuously acquired analog samples?

[neurostu]

I'm playing around with the ContAcq.c example that ships with the C API.  My goal is to be able to acquire voltage continuously while also timestamping each buffer, and then to merge the timestamps with a video feed that I will be acquiring simultaneously.

I am extremely new to DAQmx and am not sure where to start. I've been reading the example programs and the online documentation but I'm not sure what the best way to proceed is.

Hi Neurostu,

Here is a way to add a second column to your data for time that is inserted based on your sample rate and sample size.  Does this help?
