摘要
设计了护栏管显示与控制系统,给出了它们的硬件电路图。结合驱动芯片P9816的通信协议,编写了相应程序来控制护栏管的显示。系统采用控制器读取SD卡中的数据并进行处理,将处理后的数据送入护栏管,护栏管即可显示丰富多彩的内容。
The paper introduces the LED hurdle lamp display and control system, and provides the hardware circuit diagram. With the communication protocol of P9816, programs are compiled to control the display of LED hurdle lamp. In the system, the controller reads and processes the SD card data,and then sends them into LED hurdle lamp; thus the LED hurdle lamp can display a variety of patterns.
