Hello there,
I have a program that uses N analog channels to record data, they start taking data (either finite or continuously) a trigger.
I use the built in digital trigger but a software analog trigger (works well though). For now let's just worry about the digital trigger.
I am trying to record the time elapsed from when I start the program to when the trigger signal is received--that is, when the program actually starts collecting its data.
I've seen the examples of how to put a time stamp at the point of the trigger HERE. However, I have a few differences in my code--mainly that I am collecting N channels of data rather than one, which complicates it. Also I don't necessarily want the time stamp, but the time elapsed from start to receiving the trigger.
Right now I have a few ideas:
1) somehow timestamp the start of the VI, then figure out the time stamp of the trigger in a similar way to the example above, subtract the difference.
2) In debugging code, I find that probes record the last update at a certain point in the code. Is there a way to utilize this in actual code?
3) most difficult. Setting up a new channel that observes the digital channel I am triggering off of so that I can record its data continuously, wire that channel to trigger my analog channels. then i can see the time at which the trigger went off. But I am unsure of how to implement this.
Just looking for opinions as to what would be the easiest way to accomplish this task.
Also, I can post my code if desired-- I didn't because it's quite large and difficult to follow.
Thanks to everyone,
beefcake
