摘　　要：本文介绍利用一体化数字与模拟混合处理器PSOC提供的I2C固件元件来实现主节点和从节点间的数据通信。主节点通过通用串行接口UART完成与上位机的信息交换,通过I2C接口将上位机的数据转换成从节点能接受的格式,起到协议转换器的作用。从节点接收主节点的命令和数据后,对命令进行解码,采集传感器的数据并进行信息处理,将数据发送给主节点,并对本节点的外设进行驱动和控制。利用PSOC的I2C设计的测控网络结构简单、功能强、图形化集成开发环境提供原理图设计、API函数和中断支持,是一种有发展前途的I2C测控网络实现方法。This article introduces a method of using I^2C element which are produced by integrative digital and analog mixed processor named PSOC to realize data communication between host node and slave node. The host node carries out the information exchange with the upper computer via the universal serial bus UART. It fulfills the functions of the protocol converter by converting the data to the format that the slave nodes can accept via the Izc interface. After receiving commands and data from the host node, the host node decrypts the commands, collects the data from the sensor and deal with the information. In the following steps, it transmits the data to the host node while it drives and controls the peripherals from current node. For the merits of simple structure, powerful functions, graphical integrated development environment for schematic design, API functions and interrupt support, it is a promising approach to I^2C measurement ＆ control network.
