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.
Key words
