Given the widespread application of embedded systems in various fields, this article combines them with real-life scenarios to conduct in-depth reform and exploration of practical teaching for embedded systems. An experimental teaching system based on the embedded Android system has been designed, comprehensively covering key aspects such as underlying hardware operations, upper-level software development, hardware-software co-design, and comprehensive practical projects. This teaching system not only systematically imparts core knowledge and skills in embedded system hardware and software development but also effectively strengthens students’ practical abilities through a series of progressively challenging experimental content. It refines their thinking and approach to solving complex engineering problems and enhances their engineering literacy. Overall, this experimental teaching system is highly practical and plays a significant role in cultivating innovative and practically-minded embedded talents.
