STM32F103的高速以太网接口设计.pdf

STM32F103 ( , 150080) : 现代数据采集和监控系统的网络化, 对信息传输速率和传输距离 出了更高的要求采用STM32F103微控制器 和W5300 芯片搭建的网络系统, 结构简单易于实现文中通过对系统的硬件结构及总线接口的介绍, 阐明了系统的硬 件实现;通过对W5300 的驱动程序及测试方法的详细分析, 明确系统的通信过程该设计能够进行信息的高速远程传 输, 实现以太网接口功能 : STM32F103;W5300; 以太网; I R;TCP; UDP : TP368 : Fast Ethernet Interface Based on STM32F103 Yu Chunxue (Lab of Wireless Communication System,Harbin University of Seience nd Technology,Harbin 150080,China) Abstract: Modern data acquisition and control system network sets higher demands for the information transmission rate and transmis- sion distance.T he network system based on STM 32F103 microcontroller and W5300 chip, and the structure is simple, easy to imple- ment. This paper introduce the structure of the hardware and thebus of the interface, illustrate the hardware implementation; T hrough detailed analysis of drive program and test methods, its clear the systems of communication process. The design can carry out high- speed, long-range transport, T he ethernet interface function is implement.
