Timing option

[Alloush]

Hello,
I am completely new to labview but allready developed a VI and got it to run. I am using it for finite data aquisition. In my VI I click a run button to gather data, save to save it etc... as you can see from my front panel. I would like to add a timing option to when I click run. i.e I would like to have the option to run the aquisition for an amount I specify, or run it until I stop it. Should I implement this in the initialize state of the state machine, or shall i add some timing to the while loop in the run state, and how would be the best way to do it?

Thank you
Alloush

Hello Alloush!

In this case you can ask only few samples continuosnly.

But yes, you must initialise with that.

Hi Alloush,

Thanks for posting on the NI forums!

As Carmo has noted you will most likely need to include the setup of your DAQ task in a 'setup' or 'initialise' state seperate to your 'run' state. As to the exact ins and outs of what you need to do to implement this will depend on what functionality/behaviour you would like to get out of your application.

By my understanding you are looking to present your users a choice between continuous acquisition, i.e. acquire until they hit a stop button; and a finite acquisition with an option to abort the process, i.e. acquires data and will cease only when a certain number of datapoints have been acquired or when an 'abort' button is pressed. Is this correct? If I have mis-read your description then please let me know.

Thanks,

Rob
