摘要
以TCP／IP协议为基础,介绍了一种单片机上网技术实现方法,初步分析了REALTEK公司的RTL8019AS芯片的内部结构,并结合RTL8019A S芯片的特性和工作原理给出了具体的硬件设计方案、软件的实现和主要的程序流程图。该单元可以实现单片机之间或者与监控系统的接口功能。整个设计利用TCP／IP协议和有限的存储资源较好的实现了单片机资源的网络共享。
Base on TCP/IP protocol, this paper introduced a kind of realization method of MCU connecting to Ethemet, the RTL8019AS chip interior configuration is analyzed which made by REALTEK company. Refedng to the characteristics and the operation principle of RTL8019AS, the concrete scheme of hardware design, realization of program and program diagram is given. This unit can be use for interlace among MCU＇s or between monitor system and MCU. The design uses TCP/IP protocol and limited buffer to share MCU on network.
