摘要
介绍了嵌入式领域非常流行的实时操作系统μC/OS-II,分析轻型TCP/IP协议栈lwIP,详细论述在8位处理器Atmega128上μC/OS-II的移植以及网络协议栈的实现过程,指出移植过程中应该解决的重点和难点问题,并给出了相应的解决方法。最后,对该移植过程进行了充分的测试,并对测试数据进行了简要的分析,结果表明μC/OS-II以及lwIP的移植正确,运行稳定,具有较高的网络传输速率和较低的丢包率。
A extraordinary popular real-time operating system μC/OS- Ⅱ was introduced in embedded area.After light weight TCP/ IP stack lwIP was analyzed,the transportation of μC/OS- Ⅱ and the realization of network protocol were discussed on 8-bit processor Atmega128.In succession,important and difficult questions that should be solved in the transportation course were pointed out,and the according solution was given.Finally,adequate test was made for the transportation,and the data got from the test was briefly analyzed.The test result shows the transportation of μC/OS - Ⅱ and lwIP was correct, run stably, and had high transmission speed other than low rate of dropping packet,
