Want to toggle an output on and off every minute

[sean m]

Hi All,

What's the easiest way to setup a loop so that an output is toggled on/off every minute?

 Thanks.

Use the wait for next multiple (ms) function.

OK, I still don't understand how to wire it up so it will toggle each cycle through the loop?

You can either use 'wait for next multiple' in a while loop and specify how often you want the code to operate.

Or you can put all the code in a case structure, and use the current ms time for some boolean logic.

But I think the first option is a little easier.

Hi sean,

this is really very basic:

I would suggest you to visit the Academics section of NI's website to attend the free online LabView courses they offer!

Edited:

Instead of 1000ms you should wait for next 60000ms multiple. Or use an inner for loop, that waits 1000ms 60 times...

Heres one way to do it

Just check if the elapsed time is a multiple of 2 minutes (ie is divisible by 120 seconds with no remainder).

If thats true, run the case structure.

***Note this is only example code, your while loop should have a wait in it.

Thanks guys, I was able to get it working by doing a modulus 60 on the system tick count.

Thanks again for the good responses.
