I installed labview 8.0 student addition and when when putting a DAQmx vi on the block diagram it takes 2-3 minutes to just put in on. if using a DAQmx start vi it shuts the whole program down on an error.  I am trying to make something to read and display the frequecy  inputed from a usb 6008 DAQ board it someone knows how, thanks.

Hello,

You might try opening a LabVIEW DAQ example and see if that works when the VIs already exist.  To open an example in LabVIEW go to Help >> Find Examples.  Then you can browse according to Task >>Hardware Input and Output>>DAQmx>>Analog Measurements>>Voltage.  Then you can select a simple example such as Cont Acq&Graph Voltage-Int Clk.vi.   Run this example program to acquire data from a channel and then use some of the analysis VIs in LabVIEW to determine what frequency the signal is.

The speed problems that you are having might be computer related.  If this is an older computer you are working on you might check to see if it satisfies all of the minimum system requirements needed by LabVIEW.  If it is a fast comptuer it might be slowed down by other programs running in the background.  Is it just the DAQ VIs that are causing the program to run slow or do other LabVIEW functions run slow as well?  Do any other programs besides LabVIEW run slow?  Sometimes reinstalling the software or driver might also help depending on the problems you are experiencing.   Hopefully some of my suggestions help.  Please let me know if you are still encountering problems.

Have a great day,

Hi awpostal,

have you done a mass compile of the LV 8 directory (be aware it takes a night long done with LV, this tool limits the time)
if not, every time you load a daqmx VI it recompiles all vi's inside (which can be a lot)
