Create python code to drive a continously rotating servo

[mcolinj]

Ideally, we implement something like this except in python. (could do some more search for python code).

The servo requires different pulse widths for forward, neutral, reverse, so the interface should provide a set() method that takes (1, 0, -1) and then produces the appropriate pulse width using the PWM object.

You'll need to read a little about PWM and ask questions. We'll have a servo and robot for you to play with this.

/**
 * This is a driver for a continuous rotation servo with neutral at 1500us pulse
 * width.
 */

public class ContinuousRotationServo extends PWM {
    public ContinuousRotationServo(int channel) {
        super(channel);

        setBounds(1.0, 1.48, 1.5, 1.52, 2.0);
        enableDeadbandElimination(true);
    }

    @Override
    public void setBounds(double min, double dead_min, double center, double dead_max, double max) {
        super.setBounds(min, dead_min, center, dead_max, max);
    }

    public void set(double value) {
        setSpeed(value);
    }
}
