  • We proceed to develop the control software of GMACS, which is a wide-field, multi-object, moderate-resolution optical spectrograph for the Giant Magellan Telescope (GMT). Flexure Compensation System (FCS) prototype is one of the electronics and mechanical prototypes for GMACS. In this poster, we present the software design for the FCS prototype by using the software system modeling language, SysML. We also show two development tools to control the prototype that communicates via EtherCAT: using TwinCAT and Visual C++ on Windows 10, and GMT Software Development Kit (SDK) and C++ on Linux. We discuss the way to design the GMACS control software, which would not depend on the development tools.

  • GMACS is one of the first light instruments for the Giant Magellan Telescope (GMT). The development of GMACS control software follows Agile software development process, and the design of the software is based on the Unified Model Language (UML). In this poster, we present the architecture of the GMACS software and the development processes. As an example of the software development, we show the software of the Slit Mask Exchange Mechanism Prototype (SMEM-P) which is part of the GMACS Device Control Package (DCP).

  • We present the control software and its development process for a prototype of the Camera and Grating Articulation System (CGAS) for GMACS, a wide-field, multi-object, moderate-resolution optical spectrograph for the Giant Magellan Telescope (GMT). The CGAS prototype is currently designed for the camera articulation controller as a miniature model of the GMACS. The camera articulation package (CAP) is a software that controls two stepper motors to adjust the camera angle. The package is developed using Visual C++ and runs on Windows 10. We discuss the architectural design and communication route between the high-end user software and the electronics hardware.
