Re: data reader for cards

I'm not sure what your problem is. The VI you posted works fine and reads the text file you posted as well (and is actually not bad for someone who just started). If the problem is reading from an analog channel, that will depend on which card it is. If it's made by NI, you can probably read it by using the DAQmx VIs.

 

In any case, you should post the question to the LabVIEW board. You can also try posting it in your native language (in the same thread), as some people there probably speak it.

 

If you want to learn more about LabVIEW, I suggest you try looking at some of these tutorials.

I will let people in the LabVIEW board answer this.
