Can somebody tell how to actually capture digital IO data by using NI 6534 card?
I have it hooked up to a data device and I can see bit lights are flashing on signal panel.
Of course, self-test passed. I have got 32 bit data coming in with one bit clock toggling on
REG1. I believe this is a simple pattern IO. Could you tell which software should I use to
start data capture, and operation procedure?
 
Thanks.

hi,
 
i have used NI PCI-6534 for digital data acquisition in Microsoft Visual C++ Console based application....
 
all u need to do is install the driver and check the Microsoft Visual C++ support (or smth like that,,,, i don't remember right now)
and go to examples folder of the National Instruments directory where u ahve installed the driver and see the example  PatternIOExtClk smth like that..... it will help u in accomplishing ur task....
 
if u have more questions u can contact me
 
regards
abid

hello,
 
i'm a beginner with labview and i have some questions to ask
 
1) how can i rename the different channels (dev1/a0....a11) of my PCI 6251 into hydrogen, temperature,....
2) how can i change a XY graph into a waveform or the waveform into a XY graph? I'd like to insert one into the other but it depends of what is possible
3) how can i change a time expressed into string format into a time expressed in dbl format
 
thank you very much for the informations

Kristof,
 
For future reference, if you have a new question we usually ask that you create a new thread.  That being said, here are some answers to your questions.
 
1) You can use the DAQmx Create Channel VI to create a channel and wire the desired name into the "name to assign" terminal.  You can cacade multiple DAQmx Create Channel VI's to create multiple named channels.  An other way to do this is to use the Measurement and Automation Explorer (MAX) to create a virtual channel for each channel that you want to acquire.  Then you can create a task that includes all of your virtual channels.  Once you have this task you can generate LabVIEW code from this task.  To do this please refer to the DAQ Getting Started guide which can be found here.

2) I'm not totally sure what you mean by changing an XY graph info a waveform.&nbsp; An XY graph is meant for taking an array of x points and an array of y points and mapping this on the screen.&nbsp; If you have something of a waveform data type you would probably be better off graphing this on a Waveform Chart or Graph as opposed to an XY graph.
&nbsp;
3) I'm a little confused by this question as well.&nbsp; In what context would you need to convert a time expressed in a string format to a dbl format?&nbsp; What would it look like in dbl format?&nbsp; LabVIEW does have a type called "timestamp" which is usually used to denote a point in time.&nbsp; It's actually the number of seconds since 6pm 12/31/1903.&nbsp; There is a VI to convert from a number to a timestamp called "To Time Stamp" which will convert a number into a timestamp.&nbsp; You can also use the "Type Cast" VI to convert from a timestamp into a U64 integer.
&nbsp;
Something you might want to look at if you're just getting started with DAQmx is the "Learn 10 Functions in NI-DAQmx and Solve 80% of Data Acquisition Applications" Developer Zone article.&nbsp; Here's a link to it...
