面向单片机应用系统中的网络功能,根据ENC28J60适于嵌入式应用的简洁、低功耗、小封装的特点,以及Microchip TCP/IP协议栈的支持,从TCP/IP协议的配置选择和资源支持等方面,对当前流行的通讯转换器、嵌入式Web server(仪表、现场采集系统等)、交易终端I、P电话等应用进行了分析,并结合在研项目给出了硬件原理、协议裁剪、主体流程等设计。分析表明,ENC28J60用于小型的嵌入式系统,特别是基于MCU的应用系统,接口简单、开发方便、成本低。
According to ENC28J60 for embedded applications, simple, low power, small package features, as well as Microchip TCP / IP protocol stack support, from the TCP / IP protocol configuration options and resource support In the aspect, the application of the current popular communication converter, embedded Web server (instrument, field collection system, etc.), trading terminal I and P phone is analyzed. Combined with the research project, the hardware principle, protocol tailoring, Process design. Analysis shows that, ENC28J60 for small embedded systems, especially MCU-based applications, the interface is simple, easy to develop, low cost.
