[Linux-Unixlcd_driver-framebuffer

Description: 本文研究论述了基于S3C2410 LCD控制器的Linux驱动程序设计与实现,介绍了S3C2410的LCD控制器的数据和控制管脚,并给出了LCD的控制流程和LCD的控制器设置规则,参照TFT-LCD LQ092Y3DG01的逻辑要求和时序要求设计了其驱动电路,设置了主要LCD寄存器;论述了在嵌入式Linux中基于FrameBuffer机制的LCD驱动程序的实现方法。主要研究了Linux帧缓冲设备驱动程序框架,详细分析了帧缓冲设备驱动程序层次结构、核心功能模块和数据结构,设计了FrameBuffer的处理机制以及底层驱动的接口函数针对具体的LCD面板如何在嵌入式Linux中编写帧缓冲设备的驱动程序。最后在FrameBuffer机制的基础上,基于三星公司S3C2410处理器的开发平台系统地开发了嵌入式Linux下的LCD显示驱动程序,实现了简单的嵌入式GUI图形API的设计,并在LQ092Y3DG01上显示了清晰稳定的图像和汉字。测试表明该驱动通用性好,能驱动大部分的LCD;可移植性强,经过少许修改即可应用在其他嵌入式系统中,是S3C2410驱动LCD的一套较佳的解决方案
