Beginner trying to Learning CVI

[tdk]

Hi All,

What's the best way to begin learning LabWindows/CVI.  Any good online tutorials or books?  Thanks.

Cheers

Hi!

   At first, you should learn C programming language.  If you are not yet familiar with it, you can find many tutorials on-line, and good reference books.

    Relating CVI, take a look at LabWindows manuals, from ni: http://sine.ni.com/nips/nisearchservlet?nistype=psrelcon&sortby=localesort&nid=11107&lang=US&filter=%2B%28locale%3Aen%29+%2B%28phwebnt%3A1802+phwebnt%3A1801%29+%2Bnicontenttype%3Aproductmanual+%2Bmanualstatus%3Acurrent+-doctype%3Aspecifications&title=NI+LabWindows%2FCVI+for+Windows+Manuals

   There you find the quick reference http://digital.ni.com/manuals.nsf/websearch/5C157069BCE13FA786257085006B698C , and getting started, http://digital.ni.com/manuals.nsf/websearch/0FFBB89B4FB653CF8625707B0005D09A that are really useful for a first touch!

    Then, you can look NI examples, that comes with CVI, that cover many common programming tasks. You find examples in LabWindows menu, Help -->  Find examples...

   Please, let me know if this helps! Have a nice day!

Hello tdk,

In addition to Graziano's comments, National Instruments offers training courses in different regions and self-paced training on CVI.  More information on these courses can be found on the Customer Education website.

Thanks

Hi, thank you first.

but the manual you point out is so basic, i can't found some manual about CVI function(such as a "function referance") and detail infomation on CVI workflow.

could you give me some ebook link about CVI.

thanks in advance.

Thanks Graziano,  you're information was most useful!

You're welcome!

CVI used to come with some useful literature that in most recent releases is no more available, either moved to other resources or simply no more upgraded.

Among such literature there were both a User Interface Reference (here the link to the most recent manual I found in NI site, dated 1998) and a Programmer Reference (here the link: 2001). Anyway, this sum of knowledge is not lost: you will find a lot of useful resources browsing the Development Library , where you can find a huge deposit of tutorials, application notes and code samples that can help you deeping inside CVI world. Some of the application notes are also included in CVI distribution: you can find them in the LabWindows/CVI bookshelf item created in Start menu by the installation program or simply browsing the CVI directory and looking for PDF documents stored inside it.

Hi tdk,

I find that actually doing "hands-on" work is the best training / motivation to learn a new language.  A bit rough, mind you, but very effective.. 😉  I then look at examples on how to do what I am not familiar with.  This approach has a few drawback, one being that you need to find an actual project to work on.   You could look at the available examples and try to create your own version.  Plus this forum is an excellent source of help.

Roberto,

Those manuals that you refer to are no longer distributed in paper form or in .pdf with each copy of CVI, but their content is nevertheless fully included in the CVI online help. For example, you can find the Programmer Reference by selecting Help>>Contents, then clicking on the Contents tab and opening the Programmer Reference book. And you can find the User Interface Reference, also under the Contents tab, by navigating to Library Reference>>User Interface Library.

Hey All,

Thanks for the information, I am getting my hands dirty as we speak.  Upon becoming more with this environment I had afew questions I was wondering if you would be able to answer.

- What is the difference between the library and instruments
    I was trying to read in an analog waveform and found two methods.  One the old (labview way) where I define a task and start, read, stop it.  The other using the instrument file "daqmxio.fp"  where I use the function (NIDAQ_newchannelAI). Is there any difference?

- How would I implement a double buffering scheme in CVI?
  Does the DAQmx do this for me or would I have to implement it through code somehow?

Cheers,
tdk
