【摘要】 基于轮机模拟器的以太网通信的要求,提出了一种W5500网络芯片+AVR系列单片机ATmega16L的串口-网口转换器的设计方案,阐述了硬件设计以及通信软件的设计。采用W5500省去了TCP/IP协议集的编程,降低开发难度的同时缩短了开发周期。该模块具有自动更新目标IP地址功能,通过ATmega16L的编程进行SPI时序控制以及以太网配置参数设置。在轮机模拟器上进行现场调试,实现串口与以太网络的数据传输和共享。更多还原

【Abstract】 Because of the requirements of Ethernet communication of the Marine Engineer Simulator,a convert project between serial interface and Ethernet is introduced based on W5500 and ATmega16.The design of hardware,communication software program and related interfaces are described.Eliminate the programming of TCP / IP protocol suite,reduce the development effort and shorten the development cycle.更多还原
