摘要
Linux驱动是目前研究的一个热门领域,为了设计出可靠的设备驱动,设计一个基于zlg7290的字符驱动.首先设计了硬件电路,然后在此基础上给出了Linux驱动.在该驱动程序中编写了S3C2410X的IIC接口驱动程序,实现对外围器件zlg7290的读取功能,解决了驱动的稳定性和可靠性问题.对字符驱动的接口函数和数据结构做出分析,在硬件电路基础上设计如何对外围器件的收发.
Linux driver is a hot research field,in order to design a reliable device driver;a zlg7290 based character driver is designed.Firstly,the hardware circuit is designed,and then the Linux driver is given.In this driver,the IIC interface driver of S3C2410 X is written,to realize the reading function of ZLG7290,which solves the problem of stability and reliability.To character driven interface functions and data structure analysis,on the basis of hardware circuit design of peripheral devices to send and receive.
