多路彩灯控制器
综合训练内容要求
设计一台基于FPGA的多路彩灯控制器的设计。要求如下
1.彩灯从左到右逐次闪亮。然后从右到左逐次熄灭
2.彩灯两边同时亮两个,然后逐次向中间点亮
3.彩灯从左到右两个两个点亮,然后从右到左两个两个逐次点亮
4.彩灯中间两个点亮,然后同时向两边散开
5.设置节拍选择按钮,控制彩灯变化节奏
1. 工程文件
2. 程序文件
原理图
代码
3. 程序编译
4. RTL图
5. 仿真图
整体仿真图
模式1,先从左到右,再从右到左
模式2,两边同时亮2个,然后逐次向中间点亮
模式3,从左到右拉高点亮,再从右到左两个点亮
模式4,中间2个点亮,再向两边散开
分频模块
控制模块
