change experimental parameters while running the experiment

[ponnaboy]

hi,
I am performing a data acquisition using PCI-6052E card. I am also sending out two waveforms on each of the two analog output channels. I want to change the parameters of the analog output waveforms programatically. The parameters of the analog output waveforms are read from a text file (setup file).The entries in the file are like :
data
waveform1 waveform2 blocks

0.5 v 0.5 v 10
1v 1 v 10
2v 2 v 10

after every 10 iterations I need to change the parametrs. Is it possible to do this without affecting the speed of the original data-acquisition vi ?

Probibly...

A key factor is how fast you are acquiring data, how much you are reading and how fast you need to update the outputs.

Beyond this, it's hard to give specific advice without see your code and/or knowing more about your application. You might be able to do it all in one loop and you might want (or need) to break the output function out into it's own parallel loop.
