As informationization becomes more and more important, the appearance of all telecommunications industries and network technology pushes the pace of human civilization progress. Meanwhile, there is a dramatic growth of telecommunications industries and network technology and more and more facilities are connected to Ethernet. This design aims to control information passing process of net and Ethernet through Ethernet interface. Communication module applies Cortex-M3 processor STM32F103CDE based on ARM core while Ethernet control chip applies ENC28J60 produced by America Microchip Company, which is 28 pins independent Ethernet controller recently promoted by America Microchip Technology Company. Before, Ethernet control chip was not only expensive but also had many pins, Such as RTL8019、LAN91C111、AX88796L、CS8900A. All of them are only adapt to large-scale research institute, the capsulation of which is over 80 pins and the wiring is complex. However, ENC28J60 applies to IEEE 802.3 protocol and only has 28 pins, which greatly reduces space, as well as providing correspondent function to other Ethernet chip. 【KEYWORD】 The smart home ; ENC28J60；STM32；Networking。 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc294354140 1绪论 PAGEREF _Toc294354140 \h 1 HYPER
