Engine knock example work with 7.1?

Question

I am attempting to use the engine knock example program for the signal
processing toolset with version 7.1.1.  It still can't find
several subvi's dispite me installing most of the toolsets.
my setup:
Dell Laptop: P4m 2.2ghz 1g RAM: winXP SP2
LabVIEW 7.1.1 student edition complete install
Controls / image / signal processing toolsets
I have downloaded the "Mod B LV 60.llb "  version for LabVIEW 6
but  recieved the following errors on loading the main program:
Errors:
cannot find:   AI Read.vi - AI Start.vi - AI config.vi - AI
clear.vi - generate pulse train.vi - read from digital line.vi -
synthesis filter bank.vi - reconstruct one path 1D.vi - wavelet design
globals.vi
is there an updated version of this sample program for use with
7.1.1?  Where can I get the needed files to use this program?

Answer 1

Hey Todd,
The four vis that you listed are a part of the traditional DAQ driver. It looks like you don't have that driver installed or that you don't have support installed. One quick way to check and see if you have the traditional DAQ driver installed is to go to LabVIEW, then pull up the functions palette. Go to NI Measurements>>Data Acquisition. If you don't have the "data acquisition" option, then either support or the driver itself isn't installed. The next step is to go to the Measurement and Automation Explorer (Start>>Programs>>National Instruments>> Measurement & Automation). On the left hand side of the window, you'll see a directory structure. Under My system, you'll see a "software" directory. Expand it. Look for something called "Traditional DAQ". If you don't have it, then you don't have the traditional DAQ driver installed and that's the problem. To install the driver go to the following web site http://search.ni.com/nisearch/nisearchservlet?nistype=default&filter=+%2BProductLine%3A41+%2BDownloa.... I'm assuming you're using WinXP. Download and install the driver. If you have hardware physically installed in the computer when you install the driver, that adds another step. You'll have to perform a repair of the driver once it's installed. You can do this by going to Start>>Settings>>Control Panel>>Add Remove Programs>>NI Software. Then select change. That should create a list of currently installed software. Select "NI-DAQmx" and then hit the repair button.
One last note. When installing the driver, make sure you select to install support for LabVIEW. You should now see the vis that you were missing in LabVIEW and therefore the program should now run.
