簡單洗衣機控制器設計VHDL代碼Quartus仿真

名稱：簡單洗衣機控制器設計VHDL代碼Quartus仿真

軟件：Quartus

語言：VHDL

代碼功能：

洗衣機控制器設計

要求:

(1)設計一個電子定時器,控制洗衣機作如下運轉;定時啟動→正轉20秒→暫停10秒→反轉20秒→暫停10秒→定時未到回到“正轉20秒→暫停10秒→.....定時到則停止。

(2)洗滌過程由“啟動”信號開始,若定時到,需發(fā)出提示音響;

(3)用兩個數(shù)碼管顯示洗滌的預置時間(分鐘數(shù)),按倒計時方式對洗滌過程作計時顯示,直到時間到停機,用三只LED燈表示“正轉”，“反轉”?“暫?！比齻€狀態(tài)。
