I have a quick question Mike Dubreuil. YOu ping the sonar with Ping_Sonar and turn the timer on. Then once it interrupts it goed into Hardware_Interrupt_Sonar an into the switch statement for SONAR_WAIT status and you turn the timer on again. Then it goes into the switch statement for SONAR_TIMING for the next interrupt and get phase width as a measurement. Is the phase_width the time it takes for the actuall sound wave to go through the sonar, not the echo from the wall? If it is the echo value, then why start the timer in SONAR_WAIT?

Thanks Stephen
