manipulating variables

[berper]

Hi! I believe my problem is a very simple one, nevertheless i can`t figure out how to solve it. Here it goes: i'm reading the output of a millisecond timer which is in a while cycle. What i would like to do is to be able to subtract the new value with the old one, keeping the new one in order to do the same in the next cycle. Here is an example:

cycle 1: ms count= 1000

             output=1000

cycle 2: ms count=2500

             output=2500 - 1000 = 1500

cycle 3: ms count=3300

             output=3300-2500 = 800

cycle 4: ms count=4000

             output=4000-3300=700

As you con see it seems quite simple, but aint no labview expert.. jje!

Thanks in advance!!!!

shift register.  Don't know what it is?  Now is a good time to find out.

Hey,

You can use shift-registers, as in the following:
