Wait in While loop

[seafood]

Hi

I want my while loop to excute according to the time constant I set in an array, but it won't follow exactly.

For example, I set the time as 1000,1000,3000,3000...: but it's more like 1000,1000,1000,3000....sometimes. but sometimes seems correct...

What's Wrong?

Thanks in advance

Hi seafood,

use the "wait" function instead of the "wait until ...". Is your vi on a RT target? If the loop runs more, then available elements in your array, then you'll get 0 as wait time.

Thanks Mike, It works

Now I wonder how accurate this 'wait' could be? in micro seconds region or even smaller?

Hi seafood,

the help says you get a milliseconds value. If you need it more exact, then you should think about a RT target.

Bingo! If you use a RT target, you can get a subtle accuracy!
