Hi, I am trying to do almost exactly the same process and have managed to write a VI that will acquire data from 2 channels quickly enough to record any relevant data to a spreadsheet file. However, I want to be able to insert a software trigger that relies on a change in one of the files and then reads from within the circular buffer, how can I do this? The change/trigger is a dropping in the voltage signal being acquired. I can get my VI to acquire data but can't get it to wait for the trigger parameters to be met.
