摘要
基于8031单片机,研制出一种低成本的串行口扩展的LED显示接口电路,介绍其硬件电路与程序。实际运行表明,该电路可以成功地应用到以8031单片机为核心的显示设备中,且显示清晰稳定。
A low cost serial I/O driver circuit for LED Array Displayers based on single-chip 8031 is presented. Both hardware and software of the system is discussed in the article. The system worked well, providing clear and steady display.
