Filter Wheel
[ACS Components Examples]


Description

The class FilterWheel is a very simple example of a component that simulates the behavior of a generic filter wheel.  
The description of the wheel is on the CDB using the format dictated by the schema definition. It has one asynchronous method: moveFilterInBeam(...) that rotates the wheel to put selected filter in the beam. The adjust method moves the whell of the amount of steps passed as parameter. The adjust is used to calibrate the position of the filters and the slots. It also has three read-only properties: position, desc, slots.

What can I gain from this example?
