Capture Bean

Started by Thomas June 7, 2005
Hello Everyone, I was wondering if anyone has used the timer capture
bean in PE. For some reason I have configured it wrong or
misunderstand what the rising and falling edge settings stand for. I
would think that Rising edge times from Rising edge to rising. and
falling edge to falling edge, and Rising/falling edge to time that the
pulse is high. The later is what I'm trying to figure out. How do i
configure PE capture bean to measure the length from Rising edge to
falling edge(the time the pulse was high). I get weird results when I
do it. They maybe right but the measure only goes from 10us-1500us
and I only get a Delta of a couple thousand. I'm going to try it
again tomorrow with my stingray to make sure the pluses are what I
think and can monitor on the input of the scope. It seems no matter
what i configure it as it measures the rising2rising edge. Is there a
better bean to do this or should I start writing my own bean?

Thanks,
