I just know this has been covered before. Or maybe not because the answer is too obvious and I'm just too blind to see...

The manual states:
" The measured width is placed in Var. If the pulse edge never happens or the width of the pulse is too great to measure, Var is set to zero. "

So how long is "never happens" or "too great to measure"?

When I use PULSIN inside a loop to look for an IR signal it really slows things WAY down....

Thanks
