OpenServo Features

The OpenServo has a rich feature set enabling you to finely control the movement of a servo.

TWI/I2C Protocol	A standard and establised protocol to communicate with OpenServo
Configurable position	Set and forget position
High resolution position	10 bit position for high resolution control
Readable servo parameters	including, current position, speed, voltage and current
Configuration of servo	Optimise your servo with PID and motor control
Curve following	Send complex curves and trapeziod controls to the servo for advanced path following
RC PWM input	Control the OpenServo from a standard R/C pack, and still access I2C configuration

You can read a lot of information from an OpenServo, here are some live graphs captured from a Moving servo.

A short movement

Movement over a few position cycles

The OpenServo allow for fine control over the servo, including following curves. You can see the image below for a better idea of how the servo curve following functions work.

The X axis is the duration of the servo movement in ms, and the Y axis is the servo position.
