Rising edge of square wave

Hi all,

 

I'm wondering how I would go about finding the rising edge of a square wave. I can trigger true when the rising edge of a sine wave occurs but it doesn't work for a square wave. 

Any ideas would be excellent!

Post your VI.  If your data is a digital waveform it should be easy enough to say if the value at N+1 is True and the value at N is False then you just saw a rising edge.

How do you detect it with a sine wave?  I'm guessing you compare the value to 0, which is halfway between the max and min.  So you do the same for the square wave, compare it to half its amplitude (assuming the square wave's min is 0).
