Abstract


This article as a starting point to the widespread use of ordinary 8-bit microcontroller , the requirements for embedded systems connected to the Internet , based on the TCP / IP protocol and MCU embedded systems connected to the Internet program is proposed and implemented . The article outlines the first round of the proposed overhaul line network interface module design problem and prospects . Presentation compares the current domestic and foreign several major premise solutions , through a detailed analysis of the standard TCP / IP , and combined with the characteristics of the wheel on the the overhaul line network interface module , proposed a build based 8-bit microcontroller embedded Internet solutions . Paper do in-depth analysis on the basis of the TCP / IP protocol architecture , combined with the AT89C51 microcontroller 's resources , a reasonable simplification of the TCP / IP protocol , so that it can be implemented SCM . Focuses on the agreement of the Internet Protocol IP, User Datagram Protocol UDP, Internet Control Message Protocol ICMP, the physical ARP the ARP . The master of the system using eight AT89C51 microcontroller RTL8019AS NIC and Ethernet physical link , and simplified TCP / IP embedded in the AT89C51 . RTL8019AS NIC chip hardware structure and internal memory structure , as well as its method of sending and receiving data packets in hardware . In order to verify the correctness of the system design , article in C BUILDER design applications based on the TCP / IP protocol to verify the correctness of the system . The system is characterized by low cost through the existing network interface and Internet connection also can easily connect with other embedded devices .
