|
摘要
物联网的大规模形成和高速发展,使得基于以太网通信的嵌入式系统开发成为物联网应用的一个实际课题;文章设计了一种以STM32F407作为主处理器的以太网通信模块;利用32位闪存微控制器STM32F407与以太网模块CH395实现串口通信;采用CH395控制芯片内置的TCP/IP协议栈与上位机LabVIEW客户端建立数据通信,并实时发送测试数据进行实验研究;实测结果表明:基于STM32F407的以太网通信嵌入式系统工作稳定,数据传输可靠,能够满足系统设计需求。
With the large-scale formation and rapid development of Internet of things,the development of embedded system based on Ethernet communication has become a practical subject of application of Internet of things.This paper designed an Ethernet communication module with STM32 F407 as the main processor.It used 32 bit flash microcontroller STM32 F407 and Ethernet module CH395 to achieve serial communication.It was established data communication by using TCP/IP protocol stack built-in CH395 control chip and LabVIEW client.Experimental studies were obtained by sending test data in real time.The experimental results show that Ethernet communication embedded system based on STM32 F407 was stable.Data transmission is reliable and it can meet system design requirements.
