Loading Files in to arbitrary waveform

[Dhomfray]

I want to create a a waveform and stored it in an .lvm using ArbSigGen.vi.

in ArbSigMainProg I would like to load the .lvm into 'simulate arbitrary signal' everytime I press a button.

When I click on the 'simulate arbitrary signal', I click on 'define signal' and then 'load data', an error box pops up saying unable to load file. Any suggestions??

What I really want to be able to do is to load any waveform in and then adjust the duration of that waveform so the same waeform could last 0.1s to a minute

Nice

Heres ArbSigGen as well

When you write the lvm file, you need to configure it to write a header. Now the "simulate express VI" can load it just fine.

excellent, got it loaded but using ArbSigMainProg and adding a graph to the output of the 'simulate arbitrary signal' it doesn't seem to output anything. Any ideas

once again thanks

I was getting the same type of message.  I included the header as suggested and that did away with the unable to load message, but Labview does not respond when I click on the OK button.  I think this may be because I am using 10001 data points.  Is there any limitation to how many data points can be used?  Maybe this is a memory problem.  Is there any way to assign more memory to LabVIEW?  Thanks.

10001 data points in not much. Can you show us some code?
