  2. The Sardana device pool for SPEC lovers - BLISS Seminar - January 15, 2007 Agenda • What is Sardana • Guidelines • Structure • Sardana and other systems • Adding new features • Examples • Current state • Future

  3. The Sardana device pool for SPEC lovers - BLISS Seminar - January 15, 2007 What is Sardana? A software system for instrument control and data acquisition • Client-server architecture • Event driven architecture • Plug-in architecture • Scriptable • Multi-user • Open source Runtime add/update of new SW features • Enables creation of lightweight, platform rich client interfaces: • Java/ATK • IPython • PyQT • C++/QT,C++/MFC • etc Efficient, reliable, time consistent information feedback to the user Easy creation and deployment of new SW features Where have I heard this before?

  4. The Sardana device pool for SPEC lovers - BLISS Seminar - January 15, 2007 Guidelines • Long lifetime usage • Core is HW independent • HW specific code written as plug-ins • Performance • Minimize HW calls
