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?
- the example shows how to read and write specific informations from the CDB using DAO, DAL and WDAL
