【设计题目】矩阵LED字符显示控制系统设计【设计目的】1．掌握无操作系统下的硬件软件设计原理和方法；2．进一步熟悉ARM 处理器的基本结构、指令集、存储系统以及基本接口编程；3．熟悉嵌入式系统各部件的硬件初始化过程以及基本IO控制方法。

4．掌握矩阵LED 的应用原理【设计内容】1．利用sys_init初始化程序，利用串口实现PC和开发板的数据通信；2．编写S3C2410X 处理器的点阵屏驱动程序；3．编写S3C2410X 处理器的点阵屏应用程序。

4. 当程序运行等待要求从串口输入学生姓名的字符串在矩阵LED上显示出来。

【实验环境】硬件：Embest EduKit-IV 平台，ULINK2 仿真器套件，PC 机；软件：μVision IDE for ARM 集成开发环境，Windows XP。

【相关知识综述】背景知识、原理算法等一、硬件部分1．点阵屏的结构电路图1点阵屏的结构电路图上QL1-QL16为行驱动信号，每个信号控制一行， LR1～LR16 是点阵屏的列驱动信号，每一个信号控制一列。

当行信号为高电平而列信号为低电平，对应的LED 就会亮。

2，S3C2410与点阵屏的连接LL1 LL8LL7LL9图2 S3C2410ARM处理器与两片CD4094连接得到16位行选信号图以上电路可以通过S3C2410GPIO口把CPU的并行数据（16位两个字节的数据）打入到两个CD4094芯片中并锁存起来变成LL1-LL16的行选信号。

各信号的作用如下表1；3．点阵屏的保护电路图3 点阵屏的保护电路图为了保护LED 屏加了对应的电阻实现行限流作用，即LL1-LL16变为RQ1-RQ164．LED 的驱动加入行驱动电路的目的是实现LED 灯的驱动。

这样由RQ1-RQ16变为行驱动信号QL1-QL16。

Q11-QL16为图1中的行驱动信号。
