Sonar not responding

1 Attachment(s)

We are trying to use the HC-SR04 Ultrasonic range finder. However, it is not working. Our wiring successfully wires the two signals to separate ports. Our code is attached.

Re: Sonar not responding

What ultrasonic rangefinder are you using?

Re: Sonar not responding

I believe that your rangefinder is the same design as the Daventech SRF04 model and works with WPILib as described here:
http://wpilib.screenstepslive.com/s/...asonic-sensors

Be careful, it has two connections:

Echo pulse output: Causes the sensor to send an ultrasonic "ping"
Trigger pulse input: listens for the echo to return

Be sure to connect it as described in the documentation.
