Re: LIDAR Sensor has arrived!

How would one program the LIDAR Sensor for use via DIO in Java?

I don't know that you can. It's designed to work via PWM output or I2C. The I2C implementation should be pretty similar to the arduino example on their website. The PWM setup will likely just be reading analog input values but don't quote me on that.

Two possible methods:
  1. Use a low pass filter and read through analog (less programming but requires a resistor and capacitor connected to the output, or
  2. Directly measure the pwm pulse and convert the timing to distance (more programming, but the sensor just drops in and works)

I plan on eventually writing up a pwm based class due to the problems teams have had with this sensor and the onboard i2c port.
