We are trying to use the LIDAR sensor via PWM. How would we program this using Java? Right now we are trying to time the pulse length of the DigitalInput (would be PulseIn in Arduino), how would we accomplish this?

Can you link to a datasheet for the sensor?

Just so you know, there's an example code written by a ChiefDelphi user in Java (although it uses I2C).

I wasn't able to find the equivalent function to pulseIn.

The Semi-Period mode of the counter class should do this. http://wpilib.screenstepslive.com/s/4485/m/13809/l/241874-counters-measuring-rotation-counting-pulses-and-more
