长沙航空职业技术（2025 届）毕业设计（论文）基于单片机的旋转广告灯的软硬件设计学 院、系： 电子电气工程系 专 业： 应用电子技术 学 生 姓 名： 舒翔 班 级： 电子 1101 学号 12 指导老师姓名： 彭小平 职称 讲师 2025 年 5 月基于单片机的旋转广告灯的软硬件设计摘 要 广告灯是广告的主要形式之一，旋转广告灯系统简单，价格便宜，美观，有较高的应用价值。如何设计旋转广告灯，如何实现让旋转广告灯显示出动态的广告语，怎么样与上位机进行通讯，是讨论的重点。旋转广告灯的硬件设计分为4个模块，单片机模块、通讯模块、显示模块、驱动模块，单片机选用的STC12C5410芯片，通讯模块是CP2101 串口，通过串口，将数据传送到单片机内部，并与上位机进行通讯，这里需要定通讯协议，设定波特率、握手协议、等等。数据在传到单片机内部时，EEPROM 内进行读数据，写数据，将命令传给驱动ULN2803,来控制LED 灯的亮灭，显示出广告语。关键词： 旋转、广告、广告灯、单片机。Four conveyer belts simulation controlAbstractAdvertising lamp is one of the main forms of advertising, advertising lamprotating system is simple, inexpensive, beautiful, have a higher value. How to design arotating advertising lights, how to rotate ads advertising light show dynamic language,how to communicate with the host computer is the focus of the study. The hardwaredesign of rotating ads light is divided into four modules, single chip module,communication module, display module, driver module, optional STC12C5410 chipmicrocontroller, serial communication module is the CP2101, through the serial port,to transfer data to the internal microcontroller, and with the host computercommunication, there need to be communication protocol, set the baud rate, handshakeagreements, and more. When data is transmitted within the microcontroller, EEPROMdata within the read and write data, command passed to drive ULN2803, to control theLED lights light off, showing slogan.
