Most of the single-chip microcomputer experiments for engineering applications are conducted in open laboratories, and the process assessment has always been the difficulty of the assessment for open laboratory courses. In the post-epidemic era, the less gathered requirement and the lack of experimental teachers further increase the difficulty of the process assessment. In view of the above problems, an experimental teaching management system is designed and implemented for single-chip microcomputer experiment, which includes the hardware platform and the host computer. The hardware platform takes dual advanced RISC machine (ARM) as the core, which communicates with the experimental board designed by students via the serial interface, and uses the unified communication command to authenticate the experimental board. It also automatically stores the experimental data, which improves the flexibility for students to carry out experiments. Teacher can find out and read the experimental data through the host computer software, comprehensively tracking the progress of the students’ experiment, which alleviates the difficulties of process assessment. The experience can be extended to other experimental courses.
