Streamlined Airborne Software Development for Large UAVs: From Unified Data Collection to Automated Code Generation

Abstract: The aerospace industry has experienced significant transformations over the last decade, driven by technological advancements and innovative solutions in goods and personal transportation. This evolution has spurred the emergence of numerous start-ups that now face challenges traditionally encountered by established aerospace companies. Among these challenges is the efficient processing of digital intra-device communication interfaces for onboard equipment - a critical component for ensuring seamless system integration and functionality. Addressing this challenge requires solutions that emphasize clear and consistent interface descriptions, automation of processes, and reduced labor-intensive efforts. This paper presents a novel process and toolchain designed to streamline the development of digital interfaces and onboard software, which our team has successfully applied in several completed projects. The proposed approach focuses on automation and flexibility while maintaining compliance with design assurance requirements.
