public class MiniWheel
extends MotorController
implements Positioning

The class provide a simple interface for the mini filter wheel operation locates in the STELLA-SES top unit. The two important method can set the wheel in its zero position and (then) in arbitrary position specified by the wholes in the wheel. The class has syslog capabilities through the protomatter syslog classes. It is a copy of the FilterWheel class updated with the proper motor parameters.
