Sending an external trigger to LabView

Solved!
Go to solution

Dear all,

I'm quite new to LabView and I hope my question is not answered elsewhere, but I didn't find much.

 

I have a VI that does something in a loop, will receive an external (TTL) trigger and then breaks the loop. This is not a time-critical step and it doesn't matter whether it takes 10ms or 1s. Is there a (simple) way of implementing this on a PC without additional hardware required?

Hi Tho,

No.

You need some hardware capable to read a TTL signal…

Well it's possible to use the Parallel Port as an Input/Output Channel but I can't say I have ever tried it.

Hi RTSLVU,

 

I consider a parallel port as "additional hardware" nowadays…

(No simple office computer had such a port in the last 10 years.)
