ARM11嵌入式系统实时网络通信和 PWM 波输出控制的实现

摘要

通过对ARM11嵌入式系统Linux下的实时网络通信和PWM波输出控制进行研究，分析了网络通信协议和PWM波的驱动方式。在ARM11嵌入式系统下设计了PWM波控制程序，并实现网络终端服务器和客户端双进程的工作模式，解决了网络通信实时性和可靠性的问题，以及双线程工作模式数据交互冲突的问题。实际应用表明：该方式网络通信实时性强可靠性好，ARM11和计算机的资源利用率高，可远程灵活控制PWM波的输出。%Based on research about the real‐time network communication and the control of PWM wave in Linux based on ARM11 embedded system ,this paper analyzed the network communication protocol and PWM driver. A work model of double process of both server and client was designed to meet the requirements of real‐time and reliability of network commu‐nication and avoid the problem of date interactive of double thread work model. The application indicated that using this method had advantages of real‐time and reliability ,the utilization of ARM11 and computer was considerable ,and the PWM wave was easily controlled.
