labview stop-watch

[5616]

If I want to create a stop-watch in labview, what should I do?
Is there any example related to this in its library?

Hi 5616

Use the "Tick Count" VI in the Time & Dialog section.
Read the count when you press your "Start" button and read again when you press "Stop" and subtract to give you a count in milliseconds.

Hi,
Which version of LV are you using if its7 or above then inthe functions pallet yuo have a vi called elapsed time which you can make use as a stop watch.
else ifs a lower version all you have to do is use a present time before a loop and keep reading the present time inside the loop and when the elapsed time is equal to the stop time then you can stop the VI.
hope it helps
cheers

I am using the Labview version 6.1

If I am going to design a stop-watch which run "Start" and "Stop" with only one button such as a Boolean,

what should I do?

P.S. Thanks all the reply.

Hi again,

I've attached a picture of a very simplified solution using a single bool and an event structure.
The numeric displays the tick count as you press the button which can be ignored.
On release the bool displays the lapsed time. Very simple, hopefully it will give you enough of an idea.

Good luck
Neil

Can your stop watch be used as a subVI?

I'm trying to create a stop watch in Labview also. What if I wanted to save or write the time to a file or a spreadsheet. For example  I stop the watch at a certain instant of time, I want to write this instant of time to a spreadsheet. How can I do that in labview?
