Software design and code generation for the engineering graphical user interface of the ASTRI SST 2M prototype for the Cherenkov Telescope Array
ASTRI is an on going project developed in the framework of the Cherenkov Telescope Array (CTA) An end to end prototype of a dual mirror small size telescope (SST 2M) has been installed at the INAF observing station on Mt. Etna, Italy. The next step is the development of the ASTRI mini array composed of nine ASTRI SST 2M telescopes proposed to be installed at the CTA southern site. The ASTRI mini array is a collaborative and international effort carried on by Italy, Brazil and South Africa and led by the Italian National Institute of Astrophysics, INAF. To control the ASTRI telescopes, a specific ASTRI Mini Array Software System (MASS) was designed using a scalable and distributed architecture to monitor all the hardware devices for the telescopes. Using code generation we built automatically from the ASTRI Interface Control Documents a set of communication libraries and extensive Graphical User Interfaces that provide full access to the capabilities offered by the telescope hardware subsystems for testing and maintenance. Leveraging these generated libraries and components we then implemented a human designed, integrated, Engineering GUI for MASS to perform the verification of the whole prototype and test shared services such as the alarms, configurations, control systems, and scientific on line outcomes. In our experience the use of code generation dramatically reduced the amount of effort in development, integration and testing of the more basic software components and resulted in a fast software release life cycle. This approach could be valuable for the whole CTA project, characterized by a large diversity of hardware components.
