摘要
对Linux的I2C总线体系结构进行了深入讨论,在飞思卡尔半导体的MX51平台上,以MX51的I2C为主控制器,以重力感应芯片LIS33DE为从设备,实现了I2C总线驱动和设备驱动,分析了Linux2.6.31内核下驱动的工作、运行机理。
This paper discusses I2C bus architecture of Linux in detail.Based on MX51 platform of Freescale semiconductor and MX51＇s I2C controller,this paper analyses I2C bus driver and G-sensor chip LIS33DE I2C device driver and their running mechanisms in Linux 2.6.31 kernel.
