摘　　要：介绍一种以计算机和单片机为主从结构的小型LED显示系统。上位机设计的重点和核心是提取汉字点阵数据,并利用红外串行通信将显示内容发送到单片机。下位机是LPC900系列单片机和LED显示屏的硬件驱动电路,实现LED点阵屏的动态显示效果。该LED显示系统性价比高,广泛应用于自动化仪器仪表的面板及传感器的在线显示。该显示系统具有体积小(45×80×3 mm3)、重量轻、功耗低、使用方便等特点。A small-sized LED display system based on the computer and SCM was introduced.The key to design host computer was matrix data acquisition of Chinese character and then sent them to MCU through the infrared serial communication,the lower computer acted as the hardware-driver circuit for LPC900 SCMs and LED screen and made the LED display dynamically.The high performance-price ratio,45×80×3mm3 in dimension and low-power make it be widely used in instruments and serve their on-line display.
