Acquiring continuous data, but read LVM only reads first 100 points.

[GMik]

Thanks, for your help. I am currently using Labview 7.1.  Is there any way to not have the header specify 100 samples?

You can always open up the LVM after completion and change it to your own number of samples.

That is what I did with your test lvm and VI and it works fine reading all of them.

I'm just beginning to work with Labview, should I be doing this not using the DAQ Assistant instead?  Im not sure I'd know how to have it do everything I need (read/display/write) just yet completely on my own...

That's the same as specifying it in the read LVM express vi.  Can I remove the number of samples from the header completely? or do I have to specify a number?

Maybe someone can convert my VI to 7.1 for you ;).  Although, I'm not sure what changes to the LVM format NI has done from 7.1 to 8.0.  I remember between 8.2 and 8.5 they added a line to the header info which made me have to do a check to see if this change was present or not.

Hi everyone,

Nickerbokcer,

I can convert your VI to 7.1 but I'm missing your Convert to Timestamp subvi to complete the conversion. I do have to warn everyone, there were some major changes to some of the vi's and there's a chance that it won't work quite the same way as in 8.x.

GMik,

I've ran the program that you have posted up in both 7.1 and 8.x and all the data seems to be read from the file all at the same time.

I think the vi I posted (I can't open it now) has set in the read lvm to read a certain number of data points (that was the last way I saved it) and not set to "read entire file" Maybe thats why it worked?  Or actually, if it's set to read entire file it will still work and display a graph, but it only shows part of the data...?  I don't know why it works, unless there is a difference in how it works from 7.x to 8.x
