【摘要】 以太网控制器驱动程序,是基于以太网的网络协议运行的基础。CP2201是一款专门针对8位MCU应用而设计的高性能以太网控制芯片。为了开发基于CP2201的嵌入式以太网应用,应当首先设计其驱动程序。文中介绍了CP2201基于C8051F340驱动程序的设计和实现;此外,在驱动程序设计的基础上,为了验证驱动程序的正确性、合理性和可靠性。结合TCP/IP协议的相关内容和原理,移植了ARP、IP、UDP等网络协议,实现了TFTP服务器程序。CP2201驱动程序的设计例程具有一定的实用价值,对后续的研究、开发和应用有着重要的意义。更多还原

【Abstract】 The driver of an Ethernet controller is the basic software module on which to run the network protocols for applications based on Ethernet.A new Single-Chip Ethernet Controller CP2201 is specially designed for the application based on the 8 bit MCU.In order to develop the Embedded Ethernet application of CP2201,the driver design is the first step.This paper introduces the driver design of CP2201 in detail.The microcontroller used in this design is C8051F340.In order to improve the design’s practicality,TCP/IP Network communication protocols are presented briefly and the implementation of ARP,IP and UDP are studied in detail.The implementation of the TFTP sever is also discussed.Experiment results also prove the accuracy,rationality and effectiveness of the design.The design is of great practical value,so it makes great sense to the development of applications based on CP2201.更多还原
