摘要
为了设计开发一个性能良好、操作简单、跨平台、通用性强的LED大屏幕控制软件。利用QT技术,实现了从矢量字体库中获取任意大小字符的字模点阵信息,并转换成LED显示屏显示所需要的数据存储格式,完成了LED大屏幕在上位机的显示效果仿真,及上位机与控制卡通信协议的设计与实现。系统解决了目前大部分点阵LED控制软件系统字号大小固定、通用性差的问题,提高了系统的可靠性、通用性,具有较高的性价比。
In order to design a LED large screen control software with good performance,easy to operate,high universality.First,the system achieves the conversion of vector fonts to bitmap fonts,and converts it to the required data storage format of LED dis play.Second,the system use the QT application,it completes LED large screen display,designs and achieves communication pro tocol from the host computer to the control card.The system solves the problems what change the font size difficultly,poor ver satility of most dot matrix LED control software.The system is reliability,versatility,make it have more cost-effective.
