How to stop AO in while loop

[jmarotta]

I just realized that I have a problem with buffered output not stopping. In other words, I write the buffer continuously until a case that I have is true. However, AO Write never stops writing the old buffer! How do I get it to stop if these are set in a while loop, without stopping the while loop?
Thanks!

I'm not very expert in that but I would suggest few things:

- use a small size waveform to feed into the AO Write : you will improve user interface response.
- you may consider to use AO Wait after your AO Write to make sure all your waveform has been written, but you will have a discontinuity in your signal if you do a loop.
- you may need to set up separate loops, one for the AO process, another one for the other processes.

What do you do in the case statement? AO Clear stops the waveformm generation and releases the buffer.

I'm trying to make "on-the-fly" controls for a triangular wave output on 2 channels. I've modeled my VI after the function generator example. If I try to put the AO Clear VI in the case structure (actually in a sequence structure inside the case structure), I get more errors. I think this may be a programming issue, but I'm not entirely clear what the problem is...
Thanks.
