摘　　要：为了实现AVR单片机对LED点阵显示系统的控制,采用ATmega128作为下位机MCU,通过接收上位机发送的显示内容和显示模式的串行信号,实现16×32高亮点阵屏的一行多个文字或符号的显示。系统实际运行稳定,显示效果良好,便于多块点阵屏的扩展,作为高职学生的大学生实践创新有较高的实践意义。In order to control LED matrix screen systems by AVR SCM,the display of characters and symbols in one line on 16＆#215;32 highlight matrix screen was realized by using ATmega128 as the lower computer MCU,and receiving the display con-tent and display mode serial signal form host computer. The system is stable and its display effect is good. It is convenient for ex-pansion of more lattice display screen,and has high practical significance for innovative practice of higher vocational college stu-dents.
