As embedded systems become more widespread in industry it is important to investigate new ways of maintaining these systems that are less time consuming and conform to the industry standards for quality assurance. One of the key software components in many embedded systems is the controller logic whose responsibility is the coordination of sensors, actuators, user interfaces and machine interfaces. Making changes to the controller logic without having to recompile the entire system can offer major benefits to the development process. This paper introduces a lightweight scripting language for embedded systems, SC-xScript, and the environment that supports the compilation and interpretation of Sc-xScripl programs. Using Sc-xScript, application engineers can rapidly and safely test changes to the control logic, customize a product for different customers or applications, and add extra functionality to applications, all without requiring a new release of the underlying embedded software product. The strength of SC-xScript is its small size, simplicity and portability making it suitable for embedded systems. SC-xScript combines procedural constructs with matrix driven data structures.
