Linux系统下基于S3C2410X的液晶显示驱动程序的研究

主要介绍Linux下基于S3C2410X的液晶驱动程序的研究与开发。首先详细介绍LCD控制器工作原理以及S3C2410X的LCD控制器及其管脚,同时给出LCD控制寄存器的设置规则。并根据系统中的液晶参数给出具体的硬件连接图,得到LCD控制寄存器的参数。然后介绍帧缓冲的工作原理,并说明了帧缓冲2个方面的实现,提出了一种适用于S3C2410X硬件的通用的液晶显示驱动程序的编写方法。开发了相应的驱动程序,得到很好的显示效果,可以稳定运行。

Research of LCD Driver Based on S3C2410X under Linux System

This paper mainly introduces the research and development of LCD driver based on S3C2410X under Linux system.At first,a detailed account of the principle of LCD controller and LCD controller and pins of S3C2410X are given.Meanwhile,the set rules of LCD control register is given.And the hardware specific graph paper is given based on the liquid crystal parameters of the system,the parameters of LCD control register are gained.Then it introduces principle of the frame buffer,notes two aspects of the realization of the frame buffer,and develops the corresponding driver.The results show a good,stable operation.The innovation of the paper proposes a LCD driver programming method that is applicable to S3C2410X hardware and universal.
