针对现有方案自主可控性不足的弊端,提出了基于RT-Thread Nano操作系统完成LwIP以太网协议栈的移植实现以太网通信功能方案。首先,给出了RT-Thread Nano操作系统的移植方法,分析了RT-Thead Nano自动初始化机制的原理,并改进了串口控制台的数据发送方式。在操作系统的基础上完成了LwIP的移植,并测试验证了TCP通信和UDP通信。测试结果验证了基于自主RTOS的LwIP移植方案的有效性。
Abstract
In order to address shortcoming of poor independence and controllability in the current solution,a new solution is proposed to realize ethernet communication,which is the porting of LwIP stack code based on the RT-Thread Nano.Firstly,the method of porting of RT-Thread Nano is provided.Principle of automatic initialization in RT-Thread Nano is analyzed,and improves the data transmission method of the serial console.After the porting of RT-Thread Nano,the porting of LwIP code is completed.Both TCP and UDP communications are tested,and the test results have verified the effectiveness and efficiency of this solution.
