Quartus洗衣機(jī)控制器Verilog代碼遠(yuǎn)程云端平臺

名稱：Quartus洗衣機(jī)控制器Verilog代碼遠(yuǎn)程云端平臺

軟件：Quartus

語言：Verilog

代碼功能：

洗衣機(jī)控制器設(shè)計(jì)要求

設(shè)計(jì)一個電子定時器,控制洗衣機(jī)作如下運(yùn)轉(zhuǎn)定時啟動→正轉(zhuǎn)20秒→暫停10秒→反轉(zhuǎn)20秒→暫停10秒,每個循環(huán)1分鐘；

按正計(jì)時方式用兩個數(shù)碼管顯示正轉(zhuǎn)、暫停、反轉(zhuǎn)時間,同時用三只LED燈表示“正轉(zhuǎn)”“反轉(zhuǎn)”、“暫?！比齻€狀態(tài)；

用兩個數(shù)碼管顯示洗滌的預(yù)置時間(分鐘數(shù)),按倒計(jì)時方式對洗滌過程作計(jì)時顯示,時間到停機(jī),停機(jī)指示燈亮；

洗滌過程由“開始”開關(guān)開始,設(shè)置“暫停”開關(guān)。
