介绍了单片机与LON神经元芯片的接口方法 ,给出了采用双口RAM器件CY7C132为中间桥梁来完成单片机89C51与LONMC143150两个CPU之间进行数据通讯的实现方案。同时给出了通过双口RAM使单片机挂接到Lonworks现场总线控制系统的部分程序
The interface between MCU and LON neuron chip is introduced. The realization scheme of using CY7C132 dual - port RAM device as the bridge to complete data communication between two CPUs, 89C51 and LONMC143150, is presented. At the same time, it gives the part program that the single-chip microcomputer is connected to Lonworks fieldbus control system through dual-port RAM
