EDA设计报告彩灯控制器（老师：宗汝）班级：学号：姓名：一．设计要求设计能让一排灯（8只）自动改变显示花样的控制系统。

可将实验板上的一排发光二极管作为彩灯用。

控制器应有两种控制方式：◆规则变化。

变化节拍有0.5秒和0.25秒两种,交替出现,每种节拍可有8种花样,各执行一或二个周期后轮换。

彩灯变化方向有单向移动,双向移动,跳跃移动等。

◆随机变化。

变化花样相同，但节拍及花样的转换都随机出现。

二.设计方案(1).分频模块。

要产生快慢两种节拍，则首先需要有分频器模块，0.5秒和0.25秒两种则可选择四分频和八分频。

通过按键进行选择切换。

则clk为输入时钟信号，需经分频器分频并输入到LED显示电路；clr为复位清零信号，高电平有效，有效时，电路无条件的回到初始状态；OPT为频率快慢选择信号，低电平节奏快，高电平节奏慢；（2）LED显示模块。

经过分频的时钟信号输入LED显示电路中，使电路有规律的输出按照设定的各种花样变化。

xuan为选择彩灯变化花样信号，便于改变彩灯花样。

而最后就是输出彩灯变化花样led。
