摘要
介绍了一种基于ARM7结构微处理器和μC/OS-Ⅱ操作系统的嵌入式系统网络通讯的实现方法.介绍了如何在ARM7结构微处理器LPC2214上移植实时操作系统μC/OS-Ⅱ,重点讨论了网络接口的硬件设计及其驱动程序的建立过程,在此基础上引入小型TCP/IP协议栈lwIP,实现了嵌入式设备的网络通讯功能.
An Ethernet communication method for the embedded system, which based on a processor of ARM7 and an OS of μC/OS-Ⅱ , is introduced in this paper. How to migrate μC/OS-Ⅱ onto LPC2214, an ARM7 processor, is firstly described. Then design of the net interface and its drive were particular discussed. Based on these, a little weight TCP/IP stack was imported and communication between the Ethernet and the embedded system has realized.
