摘要
从设备驱动程序的作用、分类及文件操作,对设备驱动开发的相关知识作了简单介绍。通过对LCD和Framebuffer原理的说明,以ARM处理器S3C2410嵌入式芯片为平台,设计了嵌入式Linux下的基于帧缓冲的LCD设备驱动程序。通过测试程序的编译运行,在LCD上显示了彩色条纹,完成了驱动设计的要求。
The development of the device driver is introduced from the aspects of the device driver's role,classification and file operations.By introducing the theory of LCD and the framebuffer,the LCD device driver based on the framebuffer embedded in Linux is designed with the ARM processor S3C2410 embedded chip as the platform.In compiling and running the test program,the LCD displays the color stripe and the requirements of the driver design are met.
