Abstract:with the rapid development of network communication technology, extensive requirements of production and life in embedded system terminal can complete the network communication function. This paper adopts ARM as embedded development platform, embedded with network communication function. Using the embedded LPC2200 processor ARM system structure, according to the network communication system, based on various design scheme, select the recipients with TCP/IP protocol embedded operating system ucLinux. Cutting and customization system, building the file system related. On this basis, application program, Socket communication function call system, communication between the server and the client. The implementation of network access function of embedded device, embedded terminal each with network communication function can communicate, effectively improve the application scope of embedded equipment.
