Parallax PING))) Java Coding

[yash101]

Our team bought the Ping))) sensor for distance sensing. As per this forum post, we could use a PWM Y-cable to connect it to the digital sidecar. How do we code this in Java? I believe that the WPILib Ultrasonic class is meant for those sensors with an input and output.

The Ping))) has a built-in SX microcontroller with the job of generating the pulse and patiently waiting for that pulse to make it's way back. It then sends back a pulse, with a width that translates into the distance, by the multiplication of a specific constant, 2260 for centimeters and 890 for inches.

Note that the time units are in microseconds.

How do I send 30 microsecond pulse to a digital output and read back the input pulse, probably from a different pin if I use the Y-cable method?
