摘　　要：在嵌入式中,Linux渐渐成为一种流行操作系统,Linux驱动开发也成为嵌入式开发中的必备环节。介绍Linux环境下基于I2C协议的RTC驱动程序开发与实现。首先研究了Linux环境下字符设备驱动程序框架,然后介绍I2C协议,在此基础上开发基于I2C协议的RTC字符设备驱动程序。对于驱动程序,这里详细介绍其整体架构和各模块实现细节。最终成功实现了基于I2C协议的RTC驱动程序,并移植到Linux操作系统中。In embedded field,Linux OS has been more and more popular, the development of Linux driver is becoming a constituent job. Reaserch and development of RTC driver based on I^2C under Linux OS are introduced. First, research on the character device driver framework is given. Then, I^2C protocol is introduced, RTC driver based on I^2C under Linux OS is developed,the scheme and realization are proposed. Finally,RTC driver based on I^2C is realized and transplanted into Linux.
