摘　　要：针对单片机原理课程中数码管动态显示方式的教学难点,设计了一种可通过按键改变扫描频率的教具,直观展示了动态扫描的工作原理。教具以8051单片机为核心,涵盖了系统的软硬件设计和数码管的动态驱动原理。该教具与单片机原理课程联系紧密,使用简单,能激发学生学习兴趣,促进学生能力牵移。It’s difficult for students to understand the numeric display unit using dynamic scan. A kind of teaching aid is designed, and it can directly show the working principle of dynamic scan by pressing the button to change the scanning frequency. With the core of 8051 SCM（Single Chip Microcomputer）, the teaching aid covers the hardware and software design and the dynamic driving principle of the numeric display unit. Closely related to the course of SCM Principle, it is easy to use, stimulates students’ interests in learning the course, and promotes students’ ability shift.
