摘要
结合应用广泛的以太网物理接口和TCP/IP网络通信协议,设计了一个基于ARM Cortex-M3的嵌入式网络通信系统;系统选用源代码开放的RT-Thread操作系统,配合其中的LwIP协议栈,最终实现与远程网络设备间的数据通信。通过网络应用及测试表明,该系统能满足实时性和多任务的要求,并保证数据传输速率与可靠性。
An embedded network communication system with the widely used ethernet physical interface and TCP/IP proto- col is designed. Based on ARM Cortex - M3 and RT - Thread, an opened real - time operating system achieve the data com- munication between itself and remote internet equippment with the help of LwlP protocol stack. The communication test shows the system can meet the requirements of real - time and multi - tasking, and ensure the speed and reliability of data transmission.
