中文摘要: 本文介绍了嵌入式Linux帧缓冲设备驱动程序的体系结构，详细分析了其核心数据结构和编写方法。结合在ARM9处理器S3C2440平台上的开发实例，讲述了Linux2.6.33内核基于Platform总线的帧缓冲设备驱动的实现原理及开发流程。最后给出了用户空间应用程序访问帧缓冲设备的一般方法。
Abstract:This paper introduces the systematic structure of embedded Linux framebuffer device driver, and gives a detailed analysis of the key data structures and writing method. Through the example of Linux framebuffer device driver based on ARM9-CPU S3C2440, implementation principle and development process of Linux framebuffer device driver based on Platform bus in the Linux2.6.33 kernel is analyzed. Finally, it gives the general methods about the access to framebuffer device by user-space application.
keywords: framebuffer embedded Linux LCD driver platform ARM9
