普通LED点阵显示屏动态显示通常采用硬件扫描驱动，这在一些需要特殊显示的场合显得不够灵活。文中提出了一种利用PC机和单片机的通讯来实现显示屏灵活的动态显示和远程监控的设计方法，同时该方法还可以将显示内容在PC机上进行预览。-LED dot matrix display normal dynamic display commonly used hardware scan driver, which in some occasions require special display was not very flexible. This paper presents a way to use PC and microcontroller communication to achieve a dynamic and flexible display screen and remote monitoring of the design method, the method can also display a preview on the PC.
