Recording data

Hi,
I wonder if anyone could help. I want to be able to record some data
that I am continuously receiving through the serial port and am wondering
what the best way of doing this is. Could anyone give me some advice? I
want to be able to analyse the data after receiving it. I thought about
using ActiveX to dump the data in excel but wondered whether labview had any
functions to allow analysis.

Regards,
Martin.

That depends on what the data is and what type of analysis you want.
There are a wide range of functions available in the Math Analysis package
which I believe ships standard with version 5.1. Unless you have some specific
need to use Excel, then I would suggest using the functions in LabVIEW.

Hi. Doing the same sort of thing. If you just want to use LabView
to capture data that you will analyze later you could do a simple
serial receiver put the info into an array and use the dataloging
feature of Labview. The r
eason for doing this is no extra programming
involved and to me it would be the fastest method of storing data.
You can then write another vi to get the data and then do what you
want with it. Again this is just a fast method of getting data from a
serial port.

After that you can use LabView to write the data out to a
spreadsheet this is quite simple.

You can save your data as a binary vi and us MatLab to read the data
for your analysis. They say this is a faster method of saving data
and again it makes sense because there is no conversion and formatting
going on.

I guess I'm not sure if you want to do offline or online processing
and what sort of speeds is your data coming in at?
