可更新的汉字点阵显示系统上位机设计

摘要

介绍了一款以PC机为控制器的LED点阵显示系统的上位机设计。上位机发送控制命令,下位机接收并处理控制命令,由显示驱动模块驱动LED点阵显示屏的扫描显示。该系统可实现中英文字符显示、字符滚动、字体设置并可根据实际需求实现任意规格LED点阵的拼装。系统经试验后运行稳定,功耗低,且有很大的扩展空间。%This paper describes an upper computer design of LED dot matrix display system taking PC as controller.The host computer sends control commands;the next bit machine receives and processes it.And the display driver module drives the LED dot matrix display for scanning display.The system can achieve the display,a character scroll and font settings both in English and Chinese characters and according to the actual demand to realizes the LED lattice assembly of arbitrary specifications.System operation after testing is stable,low power consumption,and has lots of space for expansion.
