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。
Based on TCP / IP protocol, this paper introduces a method to realize the single-chip computer Internet access technology, and analyzes the internal structure of RTL8019AS chip of REALTEK company. The hardware design scheme is given based on the characteristics and working principle of RTL8019A S chip. The software The realization and the main program flow chart. The unit can be achieved between the MCU or the monitoring system interface functions. The entire design using TCP / IP protocol and limited storage resources to better achieve the SCM resource sharing network.
