USB interrupt timeout event handling

[Peter Huang]

Hi all,

I am new to labview, I am doing PIC and PC USB data transfer. I am wondering is there any way I can handle the timeout event generated by "VISA wait on Event" VI, so that when there is no coming data within certain time, it would continue proccess other code rather than generate a error. I am thinking of why VISA USB intterupt has a timeout. Interrupt can only be trigger whenever it is requested, any method to link a USB interrupt event to EVENT Structure rather than polling, which makes more sense to me.

Thanks & Regards

Difficult to understand your message and could you elaborate to it more exactly to problem.

Intaris means check out the USB nugget links in his signature. They take you here and here. There is some great information there about using VISA with USB. Kudos Intaris!

Yeah, sorry for being so cryptic.

I indeed meant the USB nuggets linked to in my signature.  I assumed once I had mentioned it they would be found.......  Sorry.

You should find an example of using Interrupt functions in there.
