Sattu,
In windows platforms you can use Microsoft's Speech Software
Development Kit (SDK). This is basically a library to convert text to
speech and speech recognition. Creating your ouw speech recognition
ruotines in LabVIEW is possible, however you will need advanced DSP
knowledge, and a lot of
Matt,
You can also use a datalog file. LabVIEW can write and read clusters
to a file, and as long as the cluster don't change you should be fine.
Basically your code would grab the value of each control, bundle it
into a cluster and save that cluster to a file. For reading, you read
your
Hi,
Take look at this example:

Crashing LabVIEW when calling external code is usually the way you
know that some parameters are wrong. What function are you calling?
may be I can give it a try here.
All of the suggestions here are very valuable when calling external
code. Make sure you have the right calling convetion, use C
Hi,
This is definately possible, however it may taka some work. It may
also require a C or C++ compiler to create a dll that LabVIEW can call
to get the results.
Some of the Windows SDK functions that you would need to call are
GetFileSize(), GetFileTime(), GetFileTitle(), GetFileVersionInfo().
Hi,
If you want to create AVI files from the graph, there are some tools
on the web that allow you to generate a movie out of what is displayed
in certain area of the screen; you could set one of those for the
graph and then start rcording the area where the graph is.
Just my 2 cents.

Hi,
I'm not familiar with k-Means but I have some tips that you could use:
The Sound and vibration toolset and the Signal processing toolset
offer a Zoom FFT tool that you can use to extract more detailed
information on frequency range with the same number of points. It uses
a donw-conversion

I'm not very familiar with envelope spectral analysis; however there
are a couple of links that I can recommend:

This is a good colection of customer solutions and general information

Sure, just go to http://www.ni.com/examples you can serach ther for
serial and limit your results to CVI. You should get about 12 hits
with different implementations of serial communication.
Good luck!

Hi,
CVI has a very complete library for serial communication. Programming
your own terminal would not be very hard, actually CVI ships with an
example that can give you a good idea on where to start.
You should be able to find the example at strongC:\Program
Files\National
Hi,
First the disclaimer...My knowledge of the Sun environment is very
limited. Given that; it may be possible to use launch your browser
with LabVIEW and pass it a comman line argument to print the desired
HTML file.
Just my 2 cents,

Hi,
The power spectrum will be in units of Vrms^2 which are power units.
There is a very usefull VI that you can use to easily transform the
units of your spectrum; the VI is called strongSpectrum Unit
Conversion.vi/strong. You select the type of spectrum that you have
and the units that you want
Hi,
Unfortunatelly LabVIEW does not support .NET events, if you must catch
NET messages you can probably create a dll that catshes those events
for you and transfers them to LabVIEW somehow.
You may want to look at ActiveX to send data to LabVIEW, there is a
quite complete interface that allows
Hi,
A subVI allows having up to 28 terminals and sometimes becomes hadr to
wire them. I LabVIEW 7 you have the option to view the subVIs as Icons
or as large express format. You can change any subVI (native to
LabVIEW or custom) to the express view by right clicking on it and
disable the View ans
Wayne,
Looks like a sweep sine analysis should give you a good idea about the
frequency response. Make sure that you measure the input and output
signals of the circuit; this way you can just compeir RMS values and
get the frequency response.
Another method that you may want to look into is a
Hi,
The VI IIR Cascade Filter with I.C. actually let's you pass to the
filter the initial condition of the filter's circular buffer. This
feature will help you pass any initial data for the buffer.
The use of the initial condition is reserved for cases where you are
performing a filter and you
