Comparing last two samples read in

[Sam_R]

Hey guys,

before my program begins testing a sample, it has to check that its current temperature is stable

So, I'm reading temperature information from my sample at a very low frequency (once every 5 seconds) and I basically want to compare the last two samples I've read in, and if they are the same allow the next part of the program to begin.

I thought this might involve using the collector function of Labview but I can't seem to see how I'd implement this.

Any help is much appreciated,

Sam.

use a feedback node or shift register.

Write the value to feedback node input and compare to the output
