使用电位器模拟传感器，进行模数转化，将AD值转化为温度值，实时显示在LCD上。汉字使用48*48字模，字符使用24*48字模。通过软件PCtoLCD2002提取字模。这里主要用到ADCCON寄存器。首先要使能预分频器，因为太快会没转化完，所以降低频率，设置分频比，然后是选择模拟输入通道。然后启动AD转换，该位在开始后自动清零，通过ECFLG位检查是否转化结束。ADCDAT0低10位用来存放转化来的数据。

S3C2440 启动流程及汇编代码知识
1、框架 2、启动过程 大多数ARM芯片从0地址启动 NOR启动：NOR Flash 基地址为0，片内 RAM 地址为 0X4000,0000 CPU 读出Nor上第一个指令(前四个字节)，执行 CPU继续读出其他指令执行 Nand启动：片内 4K RAM 基地址为0，Nor Flash 不可访问 2440硬件把Nand前4K内容复制到片内 RAM 然后 CPU 从0地址取出第一条指令 例如：（汇编代码） ldr sp, =4096 /* nand启动 */ ldr sp, =0x40000000+4096 /* nor启动 */ 3、几条常用汇编指令 LDR： 读内存 LDR R0， 读取地

ARM总线架构（S3C2440）
S3C2440集成了丰富了外设控制器(LCD控制器、USB Device控制器、USB Host控制器、NAND FLASH控制器、I2C控制器、SPI控制器等)。要控制这些外设就要设置相应控制器的寄存器以产生相应的驱动时序。学习S3C2440，主要是如何配置寄存器。下面是S3C2440特殊功能寄存器地址： #define rBANKCON0 (*(volatileunsigned *)0x48000004) //Boot ROM control #define rBANKCON1 (*(volatileunsigned *)0x48000008) //BANK1 control #define rBANKCON2 (*(vo

u-boot2009.11 s3c2440移植手记
奋战了好几天了 U-BOOT终于有点眉目了，虽然nandflash还没有弄好，目前还不支持从nandflash启动。先来张图片吧哈哈。 u-boot作为现在主流的bootloader同样分为boot 和 loader两部分。 boot：（靴子呵呵基础支撑作用）为第一阶段，主要是硬件设备的初始化。 loader：（装载机）为第二阶段完成初始化后将flash的内容搬运到内存ram中运行。 具体步骤我就不说了 网上很多大侠都说过了 我第一阶段boot的调试方法：点灯 （1）——cpu/arm920t/start.S 汇编 完成第一阶段后点一个灯，现象是LED1亮 （2）——board/..../xx2440.c 在init bo

s3c2440之IIS(4)S3C2440的I2S控制器
一、I2S控制器结构框图 S3C2440A的Inter-IC Sound (IIS)总线接口作为一个编解码接口连接外部8/16位立体声音频解码IC用于迷你碟机和可携式应用。IIS总线接口支持IIS总线数据格式和MSB-justified数据格式。该接口对FIFO的访问采用了DMA模式取代了中断。它可以在同一时间接收和发送数据。 图1 结构框图 1 、总线接口，寄存器组和状态机（BRFC）：总线接口逻辑和FIFO 访问由状态机控制。 2、5 位双预定标器（IPSR）：一个预定标器用于IIS 总线接口的主时钟发生器，另外一个用作外部编解码时钟发生器。 3、64 位FI
