Difference between 2 time in case structure

[amirdifraxe1]

Hello Guys,

i want to know How long the LED ( pin 13 ) was on? in this format (Minute:Second). When i click on the button, start counting the times until when i click again. i need to calculate the 2 times between the True and False case structure.

Use a shift register to hold a timestamp. Set the timestamp in one case and subtract in the other case…

Btw. we cannot edit/run/debug images with LabVIEW!

Thank you Dear, i will test it

thank you , i have attached my VI. if its possible for you can you do it like example for me ? because when i subtract it between two case error me.

Hi amir,

many of us aren't using the most recent LabVIEW version because of changes in the license scheme, so you better attach a downconverted version of your VI! (File->Save for previous)

Suggestion:

There might be simpler solutions… 😄

oh sorry Dear, i forgot it. i have attached Version 2016.

Excuse me Dear, what is the name of these components?

First one is "feedback node", under Programming -> Structures

Second one is "Boolean crossing PtByPt.vi", under Signal processing -> Point by point -> Other functions

Thank you Dear

could you please to explain these schemes? 

when i press the button(button=1), the input of crossing will be false-True then, on the selector, select True and start timing.  but on the 2 selector and feedbacks i don't understand whats happened.if i know the concepts of this method will be ok.
