Firstly,the study briefly introduces the knowledge system of the embedded system, reduces the development work of the embedded system with a high-tech threshold, and realizes the agile development ecosystem of embedded artificial intelligence. Then, the embedded development hardware is given and tested. With the intuitive experience of compiling,downloading, and running the first embedded program in a multi-functional embedded integrated development environment, students can start their journey to learn embedded systems. In terms of the hardware system corresponding to the development kit, this study describes the basic principle, circuit connection, and programming practice of some common controlled units in the embedded system, such as color lights, infrared sensors, and the tree structure of assembly project. Furthermore, a simple and practical embedded object recognition system based on image recognition is designed by using the CH32V307 microcontroller, and it can be used as a quick-start system of artificial intelligence. The teaching cases in this study are applicable to the teaching or technical training of embedded systems in colleges and universities,and they can provide a reference for application technicians in developing embedded systems.
