Event driven

[saurabh1989]

Hello,

Basically I am trying to count the number of click by the user.For that I am using an Event structure but I want that our main loop should not be halted while waiting for the event and for that an additional loop also created.But when I am click the button, count value  is not increasing and I am not able to understand why.

Word of advice:  Save your code for an older version before you post.  Most of us can't open your VI since we haven't upgraded yet.

You can directly check for the value change event of the boolean button on whose value change you want to increment the counter. look at the code and let us know if that is what you need.

I currently have LV 2011 installed. The copy saved in LV 2009 works fine.

Event are not triggered by indicator changes, but by user interactions. Associate your event with "clickB" instead of the LED.

• For counting, you should use integers.
• If you use switch until released, you will get two events, one for the press and one for the release.
• Use a more reasonable mechanical action (e.g. switch when pressed).
• The other loop should have a small wait.
• If you don't use the timeout, you also don't need a timeout event frame.
• You don't need any local variables for this

Attached is a cleanup, see if it makes sense.

I really forget that thing(compatibility).

I am uploading the vi for earlier version.

Your version is still 2012.

My solution above is also in 2012. Did you have a chance to look at it?
