：在某型军车的“姿态测量与数据存储系统”设计中，为实现嵌入式微处理器对数字罗盘集成电路HMC5843
的数据的采集，需开发运行于WinCE操作系统下的I2C驱动程序。文章首先论述了ARM9微处理器与HCM5843的
连接关系，随后论述了I2C总线的概念、工作原理与WinCE的流驱动模型等基本知识，最后以Platform Builder 5．0为
开发工具，开发了I2C驱动程序，并主要从中断服务线程IST与读函数IIC Read两个方面，介绍了驱动程序的具体实
现。实验表明，该驱动程序工作良好，顺利实现了ARM9与HMC5843之间的通信。-: In a certain type of military vehicle of the " attitude measurement and data storage systems" design, in order to achieve the embedded microprocessor integrated circuits HMC5843 digital compass data collection, to be developed to run on WinCE operating system of the I2C driver. The article first discusses the connection ARM9 microprocessor with HCM5843 relationship, and then discusses the concept of the I2C bus, working principle and WinCE stream driver model and other basic knowledge, and finally to Platform Builder 5.0 to develop tools to develop the I2C driver and mainly from the interrupt service thread function IIC Read IST and read the two aspects of the driver described the specific implementation. Experiments show that the driver works well, the smooth realization of the communication between the ARM9 and HMC5843.
