Abstract: Cultivating students’ ability to solve complex engineering problems is the basic requirement of professional certification in engineering education. Focusing on the problem of how to cultivate the innovation ability of electronic information professionals, a single-chip practical teaching case is designed to train students’ ability to solve complex engineering problems. The paper elaborates on the engineering background, design goals, project organization and implementation, and project design schemes. From the perspective of practical teaching effect, the use of teaching cases designed to cultivate students’ ability to solve complex problems can not only enable students to deepen their understanding and mastery of single-chip technology, but also enhance students’ circuit design ability, system design ability, software and hardware development ability and the ability to solve complex problems.
