名稱：簡(jiǎn)單洗衣機(jī)控制器設(shè)計(jì)VHDL代碼Quartus仿真

軟件：Quartus

語(yǔ)言：VHDL

代碼功能：

洗衣機(jī)控制器設(shè)計(jì)

要求:

(1)設(shè)計(jì)一個(gè)電子定時(shí)器,控制洗衣機(jī)作如下運(yùn)轉(zhuǎn);定時(shí)啟動(dòng)→正轉(zhuǎn)20秒→暫停10秒→反轉(zhuǎn)20秒→暫停10秒→定時(shí)未到回到“正轉(zhuǎn)20秒→暫停10秒→.....定時(shí)到則停止。

(2)洗滌過(guò)程由“啟動(dòng)”信號(hào)開(kāi)始,若定時(shí)到,需發(fā)出提示音響;

(3)用兩個(gè)數(shù)碼管顯示洗滌的預(yù)置時(shí)間(分鐘數(shù)),按倒計(jì)時(shí)方式對(duì)洗滌過(guò)程作計(jì)時(shí)顯示,直到時(shí)間到停機(jī),用三只LED燈表示“正轉(zhuǎn)”，“反轉(zhuǎn)”?“暫?！比齻€(gè)狀態(tài)。
