- Would it make sense to log the data and count it later?
- pre-calculate the zeros() and store them in a variable instead of having the zeros() inside the loop
Can you save all the values of the UserData field of a data acquisition session?

I'm acquiring data through a NiDaq device and have created a data acquisition session.
There are two fields that I created using the UserData (src.UserData.trip_type and src.UserData.trip_counter) .
I'm updating the values of these two fields when certain conditions are met (a voltage threshold) by one of the signals I'm acquiring.
This means that my UserData fields keep changing once those conditions are met, but I would like to constantly record their values, and get the timestamp of when their value changed. Is there a way to do that?

You can use this:
which is going to be identical to
(acqData(end) - acqData(1)) / (length(acqData) - 1)
You can look at "Acquire Timestamped data" section for more info in the following link:
Hope it helps!
