摘要
根据嵌入式系统与软、硬件结合紧密的特点,在基于ARM微处理器的嵌入式系统上移植实时内核μC/OS-II操作系统,并以此平台为基础,针对μC/OS-II操作系统不支持TCP/IP网络通信的问题,实现了将免费开源的TCP/IP协议栈LwIP移植到μC/OS-II操作系统上,解决了μC/OS-II操作系统的网络通信问题。开发板和局域网中的PC机网络通信实验表明,实现了嵌入式系统下TCP/IP协议栈的基本功能。构成一套完整的嵌入式系统网络通信平台,为嵌入式系统与In-ternet的网络互连提供了一种解决方法。
According to the advantage that the embedded systems link with hardware/software closely,a real time kernel μC/OS-II operation system is transplanted on the ARM micro-processor.Based on this platform,in the light of the problem that the μC/OS-II does not support TCP/IP network communication,the free TCP/IP stack and LwIP are transplanted to the μC/OS-II operation system,which realizes the μC/OS-II operation system network communication.The network communication experiment of study kit connecting with PC machine in LAN shows that the basic TCP/IP function is realized.Then an embedded network communication platform is established,which provides a method for connecting the embedded system with Internet.
