using measurement studio with my own circuit

[Bader]

Im a computer engineering student

I have designed a circuit which do analog-digital convertor and the computer reads the digital value from the parallel port, and Im looking for an application

I found this nice topic in your site : Measurement Studio Analog Output -- Waveform Generation in Visual Basic
http://zone.ni.com/devzone/conceptd.nsf/webmain/9C9F9227D165EF6C8625687E006CEFF5

and I hope that I can do it for my project

my question is : can I use the parallel port of the PC instead of National Instruments data acquisition (DAQ) hardware in the measurement studio 6.0 ??

thank you alot .

Hello,

It sounds like your question is really if you can access the parallel port from your Measurement Studio Environment. The answer is yes, and one way to do this is using NI-VISA. In general, I imagine you will be performing viOpen, viRead, and viClose operations on your parallel port. The following discussion forum links should help you get more well rounded on the idea: (note: many of these forum posts have helpful links as well!)

my friend what you are saying is correct

I need to access the measurement studio through the parallel port

so can I use the CWGraph to plot the data which read on the parallel port ??

or I have to use the Labview for this scope ??

but i dont have the labview ... is there an evolution version for it ?


thanks alot

Bader,

Once you have gotten the data from your device using the parallel port and VISA as described above, you can easily view this on a graph. You will simple want to take a single double or an array of doubles and plot them using the CWGraph.PlotY function. Let us know if you have any other questions.
