近年来，ARM linux应用范围越来越普遍,对Linux底层驱动的软硬件开发也成为硬件工程师们开发设备需要重点关注的问题。I2C总线的控制现阶段已经在嵌入式控制系统中应用越来越普及。尽管I2C的硬件体系结构不是特别复杂,然而I2C体系结构在Linux系统中的实现却特别复杂。在Linux下面编写I2C驱动最常使用的方法包括将I2C设备作为一个普通的字符设备来处理以及通过Linux I2C驱动体系结构来实现两种形式。

In recent years,ARM Linux has been applied more and more widely,has become the problem of hardware engineers develop equipment need to focus on the development of the hardware and software of the Linux driver.Control of I2C bus at present already in the embedded control system is applied more and more widely.Although the I2C hardware architecture is not particularly complex,however,the realization of I2C architecture in Linux system is particularly complex.Preparation of I2C drives the most commonly used methods include I2C equipment as an ordinary character device for processing and to realize the two forms by Linux I2C driver architecture under Linux.
