Loop Timer

[maxjperkins]

Hello,

I have a loop that executes some functions to run a camera frame by frame. I have successfully used shift registers and a millisecond timer to create a feedback loop that displays the time required to iterate one individual loop run. 

What I am really needing to do from here is to create a timer that will show me how long the loop runs for a total amount of time, given an arbitratry number of iterations. The loop executes when I hit a boolean button that creates a true condition for the case selectector that drives the camera and other code. The loop outside that simply checks the T/F boolean button for changes, and when I deselect the button the loop stops. I am trying to determine the time interval from when I first hit the button to start the loop, it iterates "i" times, and then when I hit the start button again to stop the loop.

Thanks

There are many ways to time your code, but first we'll need to see your code 🙂 I'll take a look if you upload for LV 2012. If you are using a more recent version just go to File >> Save for previous version...

I'm not sure whether I understood the problem clearly.
- you have a loop,inside that there is case structure. You want to get the total time true case executed.
- you can use elapsed time inside true case https://www.ni.com/docs/en-US/bundle/labview-api-ref/page/vi-lib/express/express-execution-control/e...
- use shift register and add this time in true case and false case simply pass it to next iteration.
-you can also use tick counts to get the time true case executed and add that timings.
-hope you are familiar with case structure,shift register and Loop. If not : https://learn.ni.com/learn/article/labview-tutorial
