摘要
通过对ARM11嵌入式系统Linux下的实时网络通信和LCD显示进行研究,分析了网络通信协议和LCD驱动方式。在ARM11嵌入式系统下设计了直接读写GPIO的LCD显示程序,并实现网络终端服务器和客户端双线程的工作模式,解决了网络通信实时性和可靠性的问题。实际应用表明:该方法LCD显示速度快、网络通信实时性强可靠性好、ARM11和计算机的资源利用率高。
According to the research of real-time network communication and LCD display based on ARM11 embedded system working in Linux,the network communication protocol and the LCD drive mode is analyzed.A LCD display program that can directly read and write GPIO was designed in ARM11 embedded system.The working mode of network terminal server and client multi-thread was achieved.It solves the real-time and reliability problems of network communication.The practical application shows that：the method realizes high-speed display of LCD,improves the real-time and reliability of network communication,and resource utilization of ARM and computer.
