嵌入式网络模块PPP TCP 运行库参考手册

norflash 代码！--norflash source code.

应用背景有关于嵌入式的多线程通信编程源代码和嵌入式网络通信源代码，代码是原创的，特别清晰，使我们的有关嵌入式的实验内容，该代码已经在arm机上运行编译通过了，如果有什么问题，运行出现什么问题，应该也是编译环境的原因，都是小问题，调试几遍就可以了。关键技术该源代码运用了嵌入式多线程通信的关键和基础技术，代码都很简单，容易看得懂，运用了信号量作为资源使用情况的标志，而且，在多线程中，有些小的变量可以自己更改。在网络通信中，有客户端代码和服务器端代码，用到了socket编程，整个建立通信连接的技术代码都有。

本源码是综合网上一些教程，成功把FreeRTOS（1.4.0）操作系统移植到STM32F4上，源码有详细的注释，相信一般都能看懂，能为后期的开发做铺垫，移植之后只需要修改一下LED的GPIO就能运行，创建多任务都可以的。

Welcome to PMOS. PMOS is a set of modules, mostly written in Modula-2, to support multitasking. PMOS was designed primarily with real-time applications in mind. It is not an operating system in the conventional sense rather, it is a collection of modules which you can import into your own programs, and which in particular allow you to write multi-threaded programs. -Welcome to PMOS.
