摘要
介绍了以ARM9处理器芯片S3C2410为基础搭建的LCD(液晶显示器)硬件电路,以及在此基础上移植嵌入式Linux之后,基于帧缓冲(Framebuffer)的LCD驱动程序的实现方法。讨论了Framebuffer的处理机制及底层驱动的接口函数,并针对具体的LCD面板,介绍了如何在μCLinux中编写帧缓冲设备的驱动程序。系统功能丰富,为各种扩展提供了基本的软硬件基础。
This paper introduces a general method to form a LCD circuit based on the platform of ARM9 $3C2410, and how to take advantage of Framebuffer for LCD drivers under Embedded Linux. It describes how the Framebuffer works and the related usage of the lower level drivers. Various functions are provided by systerm which supplies the hardware and software basis for deeper development.
