calling producer/consumer subvi using main vi for image grab acquire

[Han Yen]

Hi Bjorn,

Sorry to bother you again. I am just wondering should the IMAQWindraw be in the Consumer Loop or Producer Loop? When it is in the producer loop under timeout, no images appear. It seems to me that the image data from consumer was not passed to the Producer Loop.

But when I change it into the Consumer loop, the image did appear. So, I am just wondering whether is it better to display all the images that I get using the consumer loop?

Thanks again for all your advice and comments.

Cheers,

Han Yen

Hi Han,

The problem is that I could test this VI  My bad, ALWAYS test a VI 😉

It should work in the consumer loop cause the image data is not in the Image reference.  Like it says, it's just a reference.

What might be the problem is that it's done in the timeout.  This is not a good thing to do, if I think about it a little bit more.  because It's constantly updating even if there is no update of the image.

You can put it in the producer loop and that will work fine as you mentioned yourself, but for some reason it doesn't feel good to me to put it there.

But Hey, if it works for you and you're happy with it, GO FOR IT 😉

I don't think it will give you that much overhead, of will give you anu problems.

Have fun 😉
