use read status to stop while loop

[jmannnh]

Disclaimer: I am relatively new to LabView so this may be simple but I haven't been able to figure it out.

I want to run a chip until it generates the signal of interest. I've come up with the attached code where the while loop generates all of the inputs to the chip including a software timed clock. When PFI5 is asserted (PFI5in button pressed) the top path captures the data. When the capture process is complete I would like to terminate the while loop. Right now I get and display the data but I haven't been able to figure out how to stop the while loop.

How would I configure this diagram to get that to happen? I thought I could look at the DAQmx Read properties and look for the buffer to fill up but all I ever get is zero in the different status indicators.

Thanks

Hi,

You could use a functional global variable. Set it to false at start of top loop and true at end of top loop.

Inside the while loop read the functional global variable for a true to stop loop..

Code attached..Not tested - shud work..

Thanks,

Shane.
