Help with software install of LabWindows/CVI

[Steve Chapman]

The lab I work in just acquired th following: MIO-64E-3, NT v4, and LabWindows/CVI Full Dev Sys V 5.0.1. With this, I would simply like to do continuous data collection and save to a file. (Either 8 digital samples and 6 analog samples per sweep, or 14 analog samples per sweep.) I can't get the install figured out - need help! So many questions... 1) Which should you install first - Ni-Daq or LabWindows? 2)Which version of Ni-Daq is correct to use - 6.11 or 5.05? 3) When you install Ni-Daq, should it install an app. called simply "Ni-Daq"? 4)Where is the Advanced Analysis Library for MaxMin1D? What am I getting wrong? Any guidance would be greatly appreciated.

1) CVI first is easiest. That way NI-DAQ will detect CVI and install CVI support
2) Install the newest NI-DAQ you have.
3) You are using a pretty old DAQ board and version of DAQ. It will install a DAQ configuration software tool accessible in the start menu.
4) The Advanced Analysis library will be in your Library menu in the project window of CVI. If the Advanced Analysis library is disabled in the menu, you have the base package or you should reinstall CVI.

Chris -

After reinstalling CVI and NI-DAQ, I have
neither the Analysis library nor the Advanced
Analysis library in my Library Menu.

I used the typical (default) installation for CVI.
Should I do something different to get one of the
Analysis libraries to work (I'm fairly certain
I read somewhere that the Full Development System
(version 5.0.1) should include the Advanced Lib).

If it's possible to develop a simple program for
continuous data acquisition without calling things
like MaxMin1D, that would be fine. I just can't tell
where to get started. My only experience with A/D
boards is in the DOS environment where you do what
you need by writing directly to registers in the
board. I can't seem to get a handle on how to achieve
any
of this in Windows. I can't even tell if I've got
the tools I need.

I'm trying to find example code, but don't know where to
look. Since it is so straight forward, it seems like
there ought to be quite a few people doing it already.

Any suggestions would be appreciated greatly!!

thanks,
Steve Chapman

Please check in the project window, options >> library options menu that the Analysys checkbox is marked: if it's not, the corresponding item in the Library menu is disabled. Cvi 5.0.1 FDS should ship with Advanced Analysis.

As for DAQ acquisition, I recommend you to look in the \samples\daq directory: you'll find lots of examples from which to start in developing your application.

Thank you very much for the guidance. That was indeed
the problem with the Advanced Analysis library.

Any suggestions on an example program from the samples\daq
directory that would start me on the way to simple,
continuous,(double buffered?) acquisition? I need to
just be able to tell it a file name, then have a start
and stop button.

This forum is the most responsive and helpful that I've
ever come acrosss.Thank you very much!!

As stated before, you are using an pretty old version of NI-DAQ so I'm not sure of all the examples included. There is probably an example called DAQdoublebuf.prj that will show you how to do double buffered acquisition.
