Add trigger control at example continuous sound input vi

[survey]

Hi,

I am new on Labview programming.

I am trying to add trigger control to Labview\example\continous sound input vi but I found that the program will hault or no signal display on graph. Can anyone has any sample program or what's wrong on my vi?

Hi, it seems that you are stopping the task before even starting. From the looks on the code, it would be easier to enclose the Sound Input Read.vi and the Raw Data indicator in a case structure and use a Boolean control to determine when to read or not.

Could you give me an example how to modify my vi?

Try this one...I think this is what you were trying to do. I already test it and it's working.

It has a blink on the graph when the switch state from off to on. Is that possible to prevent?

Right click on the graph and select "Ignore Time Stamp"

It does not work.

Try this instead: take the graph outside of the case and do the same changes shown in the picture attach. The blink on the graph is the data updating in the indicator. The suggestion smooths this operation. I hope this helps
