Description: 作者：华清远见嵌入式学院。《Linux设备驱动开发详解》（08&09年度畅销榜TOP50）第15章、Linux的I2C核心、总线与设备驱动。I2C总线仅仅使用SCL、SDA这两根信号线就实现了设备之间的数据交互，极大地简化了对硬件资源和PCB板布线空间的占用。因此，I2C总线被非常广泛地应用在EEPROM、实时钟、小型LCD等设备与CPU的接口中。Linux系统定义了I2C驱动体系结构，在Linux系统中，I2C驱动由3部分组成，即I2C核心、I2C总线驱动和I2C设备驱动。这3部分相互协作，形成了非常通用、可适应性很强的I2C框架。6.1节对Linux I2C体系结构进行分析，讲解3个组成部分各自的功能及相互联系。6.2节对Linux I2C核心进行分析，讲解i2c-core.c文件的功能和主要函数的实现。6.3节、6.4节分别详细介绍I2C总线驱动和I2C设备驱动的编写方法，给出可供参考的设计模板。6.5节、6.6节以6.3节和6.4节给出的设计模板为基础，讲解S3C2410 ARM处理器I2C总线驱动及挂接在其上的SAA7113H视频模拟/数字转换芯片设备驱动的编写方法。-Author: HuaQing vision embedded institute. The Linux device driver development "(08 and 09 sep TOP50) annual list of best-selling chapter 15, Linux the I2C bus and core, device drivers. The I2C bus use only the two root, SDA SCL signal will achieve the data interaction between equipment, greatly simplified the hardware resources and PCB wiring space take up. Therefore, the I2C bus is very widely used in EEPROM, real clock, small LCD equipment and CPU interface. Linux system defines the I2C drive system structure in Linux, system, the I2C driven by three parts, namely the I2C core, the I2C bus driver and the I2C device drivers. The three parts of the cooperation and formed very general, can vary adaptive the I2C framework. Section 6.1 the I2C system for Linux analyzed the structure, the explanation is 3 part of their respective functions and to each other. Section 6.2 to Linux Platform: |
