wait a 'while loop' until new order

[vicens]

Hi,

the VI added works OK. My doubt is that: How I do to execute in only 2 loops?

This VI should do, in the first loop, switch ON the led. Soon after, when the user wishes, stop the program (and switch OFF the led) in a second loop.

Looks good to me and don't see the problem.

There aren't any problem... but I want to optimize the VI: when I stop the program it has do XXXXXX loops. I want to do 2 loops: the first to switch ON and the second to switch OFF.

Hi vicens,

you can do it like this...

I would use an event structure. Modify as needed.

(Of course it seems a bit overkill to even use a while loop for exactly 2 iterations. If you know the numer of iterations beforehand, a FOR loop is usually more appropriate. Can you explain in a few sentences what the purpose of all this is? Maybe there is a much better solution :))
