| 摘 要： | 本文提出了一种低成本、高性能的以太网串口服务器的软硬件设计方案。该服务器以Cortex-M3的芯片STM32F107VCT6为核心控制器,采用DP83848CVV以太网控制器处理网络数据,使用通信串行接口RS-232传输数据。同时,将TCP/IP协议移植到uCO/OS-III实时操作系统中,并用嵌入式系统建立实时多任务,使串口服务器能够以TCP/UDP模式在网口和串口端进行相互通信。研究证明,本服务器能实时、稳定地传输数据,并可以与设置好IP地址的网页进行相应数据的通信。

| Abstract: | This paper puts forward a kind of low cost,high performance Ethernet serial server design of the software and hardware solutions.The server uses Cortex-M3 chip STM32F107VCT6 as the core controller,selects the DP83848CVV Ethernet controller to process network data,and makes use of the communication interface RS232 to transfer serial data.At the same time,the TCP/IP protocol is transplanted into uCO/OS-III real-time operating system,and in this system builds the embedded system real-time tasks,and that the server can work in TCP/UDP mode between Ethernet interface and the serial port for write to each other.Research proves that the server can transmit data real-time,steady,and can work with web page set valid IP address for the corresponding data communications. |
