toggle when either of two inputs go high

[Rhayes]

I have two inputs when the conditions from either are met they will go high, I'm looking for logic that will toggle the output state when either of them go high but not toggle when they return back to low. I tried a JK flip flop but that's not what I'm looking for.

Please post as graphic not vi, I'm using 4.0

thanks

Ron,

Here's a couple ways. There are undoubtedly many other possibilities. Whenever either of the inputs transitions from low->high the output state will toggle, regardless of the state of the other input.

Method 1 uses the nifty (and IMHO underutilized) 'x implies y' logic block, though granted it isn't as easy to glance at and understand the behavior.

Method 2 uses logic that's more straightforward to interpret.

Hi Ron -- here is another way -- three images for all the case structures. thanks VNIU

I am sorry, I attached the stage 1 file wrong .. here is the correct one

Thanks for the code.

What are the objects with the arrows in them (in1&2 and output?), I'm new to labview and I have never seen them before. Do they exist in 4.0?

Input1 and Input2 are just boolean controls, and Output is a boolean indicator.
The arrows got added (~v6?) to help users tell controls from indicators. Back in v4 etc, you can only tell by the border
