摘 要
旋转LED显示屏是利用机械转动动态扫描代替传统逐行扫描方式,是一种新型的显示屏,具有成本低,可视范围大的特点,是LED显示屏的一个新的发展方向。其实质就是与机械转动配合起来的动态扫描显示技术。主控芯片为AT89S52,以及电机模块,时间模块,温度模块,显示模块,速度模块等辅助组件而成。本次“旋转LED显示屏”的制作用于我的毕业论文,它提高我的实践能力和专研能力,激发我对学习兴趣,引导自主学习及培养创新能力、协作精神、工程实践素质。这次的设计利用高速旋转中控制LED的亮灭,进行字符的显示,温度的监控(主控DS18B20),简单图形的显示,速度控制(主控霍尔3144),以及控制器采用单片机,完成显示内容的传输、字库的转换、显示等功能。
