1、前前前言言言言一、问题的提出:用于图文显示的LED显示屏,如果只显示一些图形、文字,而对图像、动画以及信息的实时显示要求不高,而且信息的内容和屏与屏切换相对比较稳定,不需要固定计算机实时服务,只需要在控制显示屏的单片机中加入存储块,实现信息的保存功能。通过无线发射机和无线接收机进行数据的传输,达到对LED显示屏的控制。二、论文的主要研究内容:通过软件编辑实现图文编辑与传输。采用习惯的Windows窗体,开启文本编辑区,完成图形和文字的编辑工作。在控制系统中实现字模的提取与保存,无需在单片机中加入
2、汉字库。通过采用PC与无线发射机串行通讯方式,无线接受机接收信息发送给LED显示屏,从而完成信息的传输。通过对点阵模块和控制电路的分析,确定LED显示屏的部件构成;通过对单片机及智能控制模块的分析,确定LED显示屏的组成结构和扫描驱动方式,实现LED显示屏的显示。三三三、三、、、本课题系统图本课题系统图本课题系统图本课题系统图PCRS-232 LED1目目目目录录录录······················
