1、如題,再附加上程序的控制說(shuō)明.是用GW48教學(xué)實(shí)驗(yàn)箱仿真的如果對(duì)你有幫助,請(qǐng)大家頂上.程序直接貼上了控制說(shuō)明：1、電子琴：程序設(shè)計(jì)采用八個(gè)輸入端口，分別與實(shí)驗(yàn)箱上的按鍵81引腳相連接，采用一個(gè)輸出端口，與揚(yáng)聲器的引腳連接，時(shí)鐘頻率采用6MHz和4Hz。按鍵71分別用于中音的七個(gè)音符的發(fā)音（DO，RE，MI，F(xiàn)A，SO，LA，SI），按鍵8用于控制樂(lè)曲的播放。程序的編寫(xiě)采用狀態(tài)機(jī)的編寫(xiě)方法，對(duì)按鍵的狀態(tài)進(jìn)行判斷，對(duì)應(yīng)相應(yīng)的音符或樂(lè)曲。2、電子鐘：程序的設(shè)計(jì)模塊有：時(shí)鐘初始化模塊、時(shí)鐘工作模塊、時(shí)鐘設(shè)置模塊、鬧鐘設(shè)置模塊、閏年的月份天數(shù)判斷模塊、數(shù)碼管顯示模塊、鬧鐘鈴聲模塊及其它的設(shè)置模塊。程序使

2、用8個(gè)輸入分別與8個(gè)按鍵連接，用按鍵8對(duì)應(yīng)時(shí)鐘工作狀態(tài)（work_state），當(dāng)work_state為0時(shí)，時(shí)鐘正常工作，當(dāng)work_state為1時(shí)，進(jìn)入時(shí)鐘設(shè)置狀態(tài)。按鍵7對(duì)應(yīng)輸入端口display_set控制時(shí)鐘顯示狀態(tài)（display_state），每按2次（用于產(chǎn)生上升沿觸發(fā)）則數(shù)碼管的輸出不同。Display_state與work_state相結(jié)合使用，以區(qū)分設(shè)置的參數(shù)。按鍵64對(duì)應(yīng)輸入個(gè)腳in_set，該參數(shù)共有三位，用以表示三個(gè)狀態(tài)：state_yorh （設(shè)置年或小時(shí)）、state_morm（設(shè)置月份或分鐘）、 state_dors（設(shè)置日期或秒鐘）。按鍵32對(duì)應(yīng)數(shù)值設(shè)置端

3、口up各down。Up用于產(chǎn)生上升沿觸發(fā)，當(dāng)down為0時(shí)，則每一個(gè)上升沿產(chǎn)生時(shí)，相應(yīng)的參數(shù)加1，當(dāng)down為1時(shí)，則每一個(gè)上升沿產(chǎn)生時(shí)，相應(yīng)的參數(shù)減1。按鍵1與輸入端口clock_on相連，用于鬧鐘的開(kāi)與關(guān)，當(dāng) clock_on為1時(shí)開(kāi)鬧鐘，否則關(guān)鬧鐘。揚(yáng)聲器與輸出端口speaker相連，用于輸出鬧鐘鈴聲。附錄：源程序一、 電子琴：module piano(in,clk_6MHz,clk_4Hz,song,speaker); input in,clk_6MHz,clk_4Hz,song; output speaker; reg speaker; reg7:0 state; reg song_
