资 源 简 介

I2C总线是由Philips公司开发的用于器件之间连接的2线式双向同步串行总线。Linux内核中针对I2C总线的特性,其设备驱动使用了一种特殊的体系结构。介绍了MPC8250处理器上I2C总线控制器的工作原理,并分析了Linux中I2C总线驱动的体系结构,以MPC8250上的I2C总线为例,给出了I2C总线EEPROM驱动程序的设计方法。 Abstract:  The I2C-Bus is a 2-wire bidirecTIonal synchronous serial bus that allows computer to connect to ICs,which is iniTIally developed by Philips corporaTIon.In Linux kernel,a special I2C driver architecture was developed to support I2C Bus peripheral.Based on the principles of I2C Bus controller in the MPC8250 processor and the Linux I2C driver architecture,for MPC8250′s I2C Bus as an example, the design method about EEPROM driver based upon I2C Bus is present.
