電子定時(shí)器洗衣機(jī)控制Verilog代碼Quartus 睿智FPGA開發(fā)板

名稱：電子定時(shí)器洗衣機(jī)控制Verilog代碼Quartus? ?睿智FPGA開發(fā)板

軟件：Quartus

語言：Verilog

代碼功能：

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.....

2.若定時(shí)到，則停機(jī)發(fā)出音響信號(hào)。

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)洗滌過程作計(jì)時(shí)顯示，直到時(shí)間到停機(jī);洗滌過程由“開始”。

4.三只LED燈表示“正轉(zhuǎn)”、“反轉(zhuǎn)”，“暫?！比齻€(gè)狀態(tài)。

定時(shí)器定時(shí),數(shù)碼管顯示預(yù)置分鐘數(shù),led燈顯示三個(gè)狀態(tài),定時(shí)結(jié)束發(fā)出音響信號(hào)。
