Want to toggle an output on and off every minute

Solved!

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...

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.
