轻型PPP协议在μC/OS-II操作系统中的实现

Implementation of light PPP in μC/OS-II Operating System

针对实时操作系统μC/OS-II没有自己的网络协议栈,提出了基于ARM7TDMI处理器的μC/OS-II操作系统上轻型PPP协议的设计与实现,对μC/OS-II与处理器相关的代码部分进行了修改与编译,实现了μC/OS-II在ARM开发板上移植,为PPP协议的设计与实现提供了系统软件开发平台。通过编写了PPP协议main主模块、LCP模块、PAP模块、NCP模块和PPP等模块代码,在μC/OS-II操作系统中实现了轻型PPP协议。通过测试,验证了ARM开发板的PPP协议的网络通信功能。

Aiming at the μC/OS-II Real-time operating system without its own network protocol stack,a light PPP protocol is presented and implemented in μC/OS-II based on AMR7TDMI processor, by modifying and compiling core cedes related with AMR7TDMI processor, μC/OS-II is ported in ARM development board, which provides software platform for design and implementation of a PPP. In the end, the article introduces the course of design and implementation of a PPP under the software and hardware platform , including design of main module, LCP module, PAP module, NCP module and PPP module.Test result indicated that light PPP can be realized successfully in ARM development board.
