2种模式洗衣机控制器设计VHDL代码Quartus仿真

名称：2种模式洗衣机控制器设计VHDL代码Quartus仿真

软件：Quartus

语言：VHDL

代码功能：

2种模式洗衣机控制器

1、具有2种模式，正常洗涤和轻柔洗涤模式，通过led灯指示

2、可以通过按键设置时间，具有启动按键

3、开始后倒计时显示时间，led指示正转、反转、暂停

4、洗衣结束报警提示

5、正常洗涤模式下，正转20秒，暂停10秒，反转20秒，再暂停10秒，如此循环

6、轻柔洗涤模式下，正转25秒，暂停5秒，反转25秒，再暂停5秒，如此循环

整体仿真图

模式设置为，10代表轻柔洗涤，时间设置为5分钟，启动

轻柔洗涤，电机led[2:0]表示，正转25s，暂停5s，反转25s，暂停5s。倒计时结束后end_led拉高提示。

设置模式为01，代表正常洗涤，时间设置为5分钟，启动

正常洗涤电机led[2:0]表示，正转20s，暂停10s，反转20s，暂停10s。
