LDmicro Forum - Measuring Frequency of Square Wave Input

Measuring Frequency of Square Wave Input (by Lance Barnes)
I just recently downloaded ldmicro and I'm trying to figure out how to measure the frequency of a square wave input signal. I think I could do it if I could use a timer of some sort but I'm just not sure how to do this with the ladder logic on ldmicro. If someone can help I would really appreciate it. Thanks!
