摘　　要：汽车用LED流水灯不仅能够承担相应照明、信号显示等功能,还兼具酷炫的装饰性能,目前已广泛应用于汽车前照灯、转向信号指示灯、制动指示灯、后视镜灯、仪表盘灯、车内氛围灯等诸多场景。本文基于STC(宏晶)公司的51单片机STC89C52RC,对单片机最小系统及8位LED硬件电路进行设计,并利用Keil uVision5集成开发环境进行C语言软件编程设计,分别采用位输出操作、移位操作及循环移位操作3种控制方案实现8位汽车用LED流水灯仿真设计,经过调试验证,3种控制方案均能有效实现流水显示效果,其中循环移位操作控制程序最为简洁。The LED flow lamp for automobile can not only bear the corresponding lighting,signal display and other functions,but also have cool decorative performance.At present,it has been widely used in many scenes such as automobile headlights,steering lights,brake lights,rear-view mirror lights,instrument panel lights,and interior atmosphere lights.Based on the 51 SCM STC89C52RC of STC company,this paper designs the minimum system of the SCM and the 8-bit LED hardware circuit,and uses the Keil uVision5 integrated development environment to carry out the C language software programming design.The three control schemes of bit output operation,shift operation and cyclic shift operation are respectively used to realize the simulation design of the 8-bit automobile LED running water light.After debugging and verification,the three control schemes can effectively achieve the running water effect.And the control program of cyclic shift operation is the most concise.
