| 摘 要： | 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I^2C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。

| Abstract: | Limit In the design of attitude measurement and data storage system for some military vehicle, I^2C driver is developed for microprocessor＇s gathering data from HMC5843. In this paper, the connection between ARM microprocessor and HMC5843 is firstly introduced. Subsequently, the concept, working principle of I^2C bus and the module of streaming driver of WinCE is introduced. Finally, using the tool of Platform builder 5. 0, I^2C driver is developed. The realization of Interrupt Service Thread （IST） and IIC_Read reading function is mainly detailed. Corresponding experiments show that the driver words well and the communication between ARM9 and HMC5843 is realized as expected. |
