VI

[klpf]

Hi,

it doesn't work. why ?

Hi,

It looks like it should run to me.

As to "it doesn't work" - what do you want it to do? What does it currently do? In what way does it "not work"?

THINK Dataflow and initialize the shift register with a starting value. Otherwise it will start with zero for the first execution of your VI. And 0*2 = 0...

Of course it doesn't work. A picture can't be executed...

You're definitely going to have to provide more information. I suspect that it does exactly what you programmed it to do - put out an array of 5 zero's and a numeric zero. I'm sure this is not what you want, but until you tell us what you want us to do it is impossible to tell you how to make it work.

Actually, it will start with whatever was in the shift register last, making it even worse.  (On the first run, of course, it will be zero.)

The most annoying thing about being a software developer is that code does what you tell it to do, and not necessarily what you want it to do.  The more experience you have, the more likely it is for those two results to converge...
