I need to make a sound when data is above limit without causing delay

[JakeHappiness]

I have a program that reads values from an arduino at about 1000 hz via VISA.

When a value gets above a predetermined limit, I want to play a .wav file or a tone but have it cease as soon as value is back below the limit.

I also need this monitor function to not make the acquisition thread wait.

Any help is most appreciated.

here is the vi

Hi Jake,

when the playing of those sounds should not interfere with data acquisition then you need to move this into their own loop running in parallel…

(Cleaning up your VI is recommended, too.)

You might find a Notifier useful for communicating the status of your primary loop to the sound-playing loop.

Gerd,

Thank you for your help.

I have been having trouble understanding  the parallel loop.  Are the yellow highlighted loops below parallel to the main one?  If not will you be so kind as to help me understand what a parallel loop is?

Thank you very much!

No.  They are not even loops, they are just case structures.

They aren't even parallel to the bigger case structure since they require an output from the big case structure before they can execute.

I would recommend you learn more about LabVIEW from here. How to Learn LV

PS:  You don't need to duplicate the Index Array.  It is expandable by dragging the bottom border giving you multiple outputs.  By default they'll give you 0, 1, 2, 3 indices if you don't wire up the index terminals.

RavensFan,

Thank you for your thoughts!

Much appreciated!

Thank you Cbutcher,

I'll check that out.
