摘　　要：LED点阵由于其独特的显示效果在单片机教学中深受学生喜爱,8×8点阵模块可满足课程学习的需要但不适合单片机课程的实训教学。利用74HC138和74HC595芯片设计了一种可级联的16×16室内LED点阵模组,使用单片机作为控制芯片,将12个显示模组级联,搭建了一个32×96室内用LED显示屏实训系统并进行了显示效果实验。此系统模块化设计,可根据需要自由组合,搭建简易,学生可将主要精力集中在显示效果的程序实现中,也可满足不同系统中对LED显示的要求。The LED dot matrix experiment is popular among students because of its unique display effect. The 8*8 dot matrix module can meet the needs of the course learning but is not suitable for the practical training teaching of MCU. Using 74 HC138 and 74 HC595 chips, a cascaded 16*16 indoor LED dot matrix module is designed, and a single chip microcomputer is used as the control chip. A 32*96 indoor LED display system was built by cascading 12 display modules and the display effect experiment was carried out. The modular design of the display system can be combined freely according to needs and is easy to set up. Students can concentrate on the program realization of display effect to meet the requirements of LED display effect in different systems.
