Imitate boolean switch behavior using an event structure on a front panel indicator

[LordSnow]

Hi,

I am looking for a possibility to imitate the bevhavior of a boolean switch with an event structure. To be more precise, I want a boolean value to change each time I click on the front panel indicator and then remain constant until I click again. I have not worked with shift registers in a while loop yet, but could this be a way to find a solution?

Hi Snow,

definitely yes...

Okay, I figured it out, BUT I still have a problem. Before I first trigger a mouse event on the front panel indicator, I already need the case structure to be executed once. Therefore I assume that I need some kind of default value, but since the event structure does not create any output at first, I have no idea how to do that.

One method to get this type of behavior is to use the timeout event for initialization

Are you talking about the shift register you just created?  You can while in a default value on the left shift register ndoe.  It is wired outside of the loop.
