八、总结和结论
一、设计任务要求
1、基本要求：
1.固定红色显示一个汉字或图形，显示亮度4级可调，用一个btn按钮实现亮度调节，亮度变化视觉效果要尽量明显。
2.用从红到绿8级渐变色显示一个固定汉字或图形。
3.分别用单字循环显示、左右滚动显示、上下滚动显示三种显示方式单色显示四个汉字或图形，显示过程中，显示方式用一个btn按键进行切换。
4,。
显示的图形或汉字要尽量饱满美观。
2、提高要求：
1.滚动显示过程中实现四种显示颜色的自动变换，颜色变化视觉效果要尽量明显。
2.自拟其它功能。
二、系统设计
1、设计框图
1、系统结构框图
本系统主要由三个模块组成，其中控制器用于控制程序运行、储存当前状态并控制输出显示，点阵用于显示游戏界面，按钮输入用于输入控制信息。
2、逻辑划分方框图
3、系统流程图
4、MDS图
游戏运行状态的具体状态转移图
三、仿真波形及波形分析
逐行扫描，并点亮红灯，改变红灯的占空比可以得到不同亮度的显示。
逐行扫描，并点亮红绿灯，改变红绿灯的占空比可以得到不同颜色的显示。
上下及左右滚动显示，因为显示变化时延过长，波形过密，不方便显示。
按一次键，只产生一个脉冲，脉冲宽度为防抖动时钟的脉宽。
