S3C2410 LCD驱动学习心得-4
3. BMP和JPEG图形显示程序3.1 在LCD上显示BMP或JPEG图片的主流程图首先，在程序开始前。
要在nfs/dev目录下创建LCD的设备结点，设备名fb0,设备类型为字符设备，主设备号为29，次设备号为0。
命令如下：mknod fb0 c 29 0在LCD上显示图象的主流程图如图3.1所示。
程序一开始要调用open函数打开设备，然后调用ioctl获取设备相关信息，接下来就是读取图形文件数据，把图象的RGB值映射到显存中，这部分是图象显示的核心。
对于JPEG格式的图片，要先经过JPEG解码才能得到RGB 数据，本项目中直接才用现成的JPEG库进行解码。
对于bmp格式的图片，则可以直接从文件里面提取其RGB数据。
要从一个bmp文件里面把图片数据阵列提取出来，首先必须知道bmp文件的格式。
下面来详细介绍bmp文件的格式。
图3.13.2 bmp位图格式分析位图文件可看成由四个部分组成：位图文件头、位图信息头、彩色表和定义位图的字节阵列。
如图3.2所示。
图3.2文件头中各个段的地址及其内容如图3.3。
图3.3位图文件头数据结构包含BMP图象文件的类型，显示内容等信息。
它的数据结构如下定义：Typedef struct{int bfType；//表明位图文件的类型，必须为BMlong bfSize；//表明位图文件的大小，以字节为单位int bfReserved1；//属于保留字，必须为本0int bfReserved2；//也是保留字，必须为本0long bfOffBits；//位图阵列的起始位置，以字节为单位} BITMAPFILEHEADER；图3.4 位图文件头的数据结构（2）信息头中各个段的地址及其内容如图3.5所示。
图3.5位图信息头的数据结构包含了有关BMP图象的宽，高，压缩方法等信息，它的C语言数据结构如图3.6所示。
Typedef struct {long biSize；//指出本数据结构所需要的字节数long biWidth；//以象素为单位，给出BMP图象的宽度long biHeight；//以象素为单位，给出BMP图象的高度int biPlanes；//输出设备的位平面数，必须置为1int biBitCount；//给出每个象素的位数long biCompress；//给出位图的压缩类型long biSizeImage；//给出图象字节数的多少long biXPelsPerMeter；//图像的水平分辨率long biYPelsPerMeter；//图象的垂直分辨率long biClrUsed；//调色板中图象实际使用的颜色素数long biClrImportant；//给出重要颜色的索引值} BITMAPINFOHEADER；图3.6 BITMAPINFOHEADER数据结构（3）对于象素小于或等于16位的图片，都有一个颜色表用来给图象数据阵列提供颜色索引，其中的每块数据都以B、G、R的顺序排列，还有一个是reserved保留位。

S3C2410处理器中的LCD控制器内含寄存器 LCDCOM1-LCDCON5。对于LQ080V3DG01，这些寄存 器的具体设置如下： （1）在LCDCON1中，CLKVAL是时钟参数，对于 LQ080V3DG01，该域值取1。PNRMODE是显示模式参数， 该域值取3，表示所用模块是TFT型，BPPMODE是每个象素 的数据位数参数，对于LQ080V3DG01模块，设计时可设置 成16bpp，所以此域值取12。 （2）在LCDCON2中，VBPD对应于表1中的H参数， 该域值取32。LINEVAL对应于表1中的I参数，该域值取479， VFPD对应于表1中的J参数，该域值取9，VSPW对应于表1 中的G参数，该域值取1。

在该显示系统的硬件电路中，S3C2410与LCD 模块的连接是关键，S3C2410内部自带一个LCD驱 动控制器，其接口可以与单色、灰度、彩色STN型 和彩色TFT型的LCD直接相连，但需要根据所连接 TFT LCD 的LCD的类型设置相应寄存器中的显示模式（见下 节Q080V3DG01要求其电源电压Vdd典型值 为3.3V/5V，并且LCD数据和控制信号的高电平输 入电压Vih在2.3-5.5V范围内，低电平输入电压Vil 则在-0.3-0.9V范围内，故可以直接与S3C2410相 连，其电路图如图2所示。

嵌入式Linux下S3C2410的调色板彩色显示
嵌入式Linux下S3C2410的调色板彩色显示对于一个显示设备，数据的更新率正比于画面的像素数和颜色深度的乘积。
在系统中，受处理器资源配置和运算能力的制约，当用法大辨别率显示时(如在一些屏幕尺寸较大的终端上，往往需要640×480以上)，需要降低显示的颜色深度。
否则，因为数据处理负担过重会造成画面的颤动和不连贯。
这时，调色板技术将发挥重要作用。
9内核的在国内的嵌入式领域有着广泛的应用，芯片中带有控制器，可支持多种辨别率、多种色彩深度的LCD显示输出。
在此，将S3C2410的调色板技术，以及嵌入式Linux系统下调色板显示的实现办法举行分析。
1 S3C2410调色板技术概述1．1 调色板的概念在计算机图像技术中，一个像素的色彩是由它的R，G，B重量表示的，每个重量又经过量化，一个像素总的量化级数就是这个显示系统的色彩深度。
量化级数越高，可以表示的色彩也就越多，终于的图像也就越逼真。
当量化级数达到16位以上时，被称为真彩色。
但是，量化级数越高，就需要越高的数据宽度，给处理器带来的负担也就越重；量化级数在8位以下时，所能表达的色彩又太少，不能够满足用户特定的需求。
为了解决这个问题，可以实行调色板技术。
所谓调色板，就是在低色彩深度的模式下，在有限的像素值与RGB色彩之间建立对应关系的一个线性表。
比如说，从全部的16位彩色中抽取一定数量的色彩，编制索引。
当需要用法某种彩色时，不需要对这种色彩的RGB重量举行描述，只需要引用它的索引号，就可以用法户选取自己需要的色彩。
索引号的编码长度远远小于RGB重量的编码长度，因此在彩色显示的同时，也大大减轻了系统的负担。
以256色调色板为例，调色板中存储256种色彩的RGB值，每种色彩的RGB值是16位。
用这256种色彩编制索引时，从OOH～FFH只需要8位数据宽度，而每个索引所对应的色彩却是16位宽度的色彩信息。

六ARM9(S3C2440)的LCD 显示-理论知识
今天和大家一起讨论一下S3C2440 的LCD 显示的问题，希望大家能够多多指教，我说的不对的地方希望大家及时帮我改正，以使我可以增长知识，才
能不至于给别人的学习带来不便，呵呵下面先看一下我从别人那转过来的一篇
文章，我觉得很有用，看完之后我再说一下自己对这一块的了解，也可以先看
看我的理解（下面红字标出）再看开始的这篇文章，因为我说的更通俗，
O(∩_∩)O 哈哈~。
1. LCD 工作的硬件需求：
要使一块LCD 正常的显示文字或图像，不仅需要LCD 驱动器，而且还需要
相应的LCD 控制器。
在通常情况下，生产厂商把LCD 驱动器会以COF/COG 的形式与LCD 玻璃基板制作在一起，而LCD 控制器则是由外部的电路来实现，现在很多的MCU 内部都集成了LCD 控制器，如S 3C2410/2440 等。
通过LCD 控制器就可以产生LCD 驱动器所需要的控制信号来控制STN/TFT 屏了。
2. S3C2440 内部LCD 控制器结构图：
我们根据数据手册来描述一下这个集成在S3C2440 内部的LCD 控制器：
a：LCD 控制器由REGBANK、LCDCDMA、TIMEGEN、VIDPRCS 寄存器组成；
b：REGBANK 由17 个可编程的寄存器组和一块256*16 的调色板内存组成，它们用来配置LCD 控制器的；
c：LCDCDMA 是一个专用的DMA，它能自动地把在侦内存中的视频数据传送到LCD 驱动器，通过使用这个DMA 通道，视频数据在不需要CPU 的干预。

s3c2440的LCD字符显示在上一篇文章中，我们详细介绍了如何驱动LCD，对于在LCD屏上呈现各种简单的图形已经不是一件高不可攀的难事。
但如何绘制字符呢？其实每一字符就是一幅图像，字符的大小对应于图像的大小，字符的笔画对应于图像的内容。
那么如何把字符转换为图像呢？简单的方法是使用“字模提取”之类的软件，它能够把任意的字符转换为一个字节型的数组，数组元素中的每一位代表LCD上的一个像素点，当为1时，表示该位置为字符的一个笔画，需要上色，而为0时，表示不是笔画，不需要上色。
例如，一个字符想要在16×16的面积上显示，即该字符的宽和高各为16个像素，因为每一个像素用一位来表示，因此用字模提取软件生成的字节型数组，一共有16×16÷8＝32个字节。
在字模提取的过程中，还要注意取模的顺序，顺序不同，得到的数组就不同，一般来说是从字符的左上角开始，从左向右，从上到下取模，这样程序编写上会方便一些。
相同字体大小的中文字符和ASCII码字符的宽度还有所不同，一般ASCII码字符的宽度是中文字符宽度的一半，所以显示中文字符的程序和显示ASCII码字符的程序还略有不同。
当把一个字符取模变成一个数组后，只要对该数组中每个元素的每一位依次进行判断，对值为1的位和值为0的位进行不同的上色处理，即可完成一个字符的绘制。
下面的程序给出了一个简单的显示中文字符和ASCII字符的例子，我是用PCtoLCD这款软件来提取程序中想要显示的字符的。
