單片機(jī)課程設(shè)計(jì)報(bào)告電子琴

1、電子音調(diào)發(fā)生器一、實(shí)驗(yàn)?zāi)康?. 了解計(jì)算機(jī)發(fā)聲原理。2. 熟悉定時(shí)器和鍵盤掃描電路的工作原理及編程方法。實(shí)驗(yàn)完成的功能1. 利用鍵盤17進(jìn)行音調(diào)選擇，即按下音符產(chǎn)生對(duì)應(yīng)音調(diào)。2. 事先存儲(chǔ)三首歌曲，并可進(jìn)行選擇播放。3. 譜曲功能：通過按鍵對(duì)LCD菜單選項(xiàng)進(jìn)行選擇，進(jìn)入譜曲界面，通過按鍵17分別輸入音高與幾分音符類型，由按鍵輸入若干數(shù)據(jù)完成譜曲。4. 在播放存儲(chǔ)歌曲與譜曲播放時(shí)，對(duì)應(yīng)音符及其節(jié)奏LCD顯示對(duì)應(yīng)頻譜。5. 在播放音樂時(shí)按“返回”鍵出現(xiàn)返回界面，由鍵盤按“確認(rèn)”鍵選擇返回 主菜單或循環(huán)播放。三、實(shí)驗(yàn)原理1.音節(jié)由不同頻率的方波產(chǎn)生，音節(jié)與頻率的關(guān)系如表（1）所示。要產(chǎn)生 音頻方波，

2、只要計(jì)算出某一音頻的周期（1 /頻率），然后將此周期除以2,即 為半周期的時(shí)間。利用計(jì)時(shí)器計(jì)時(shí)此半周期時(shí)間，每當(dāng)計(jì)時(shí)到后就將輸出方波的 I/O（P1.7）反相，然后重復(fù)計(jì)時(shí)此半周期時(shí)間再對(duì)I/O反相，就可在P1.7腳得 到此頻率的方波。將P1.7經(jīng)過驅(qū)動(dòng)電路與蜂鳴器相連，隨著P1.7 口輸出不同頻 率的方波，蜂鳴器便會(huì)發(fā)出不同的聲音。音樂的節(jié)拍是由延時(shí)實(shí)現(xiàn)的，如果1拍的時(shí)間為0.4秒，1/4拍是0.1秒。只要設(shè)定延時(shí)時(shí)間，就可得到節(jié)拍的時(shí)間。 延時(shí)實(shí)現(xiàn)基本延時(shí)時(shí)間，節(jié)拍值只能是它的整數(shù)倍。每個(gè)音節(jié)相應(yīng)的定時(shí)器初值計(jì)算公式如下：（1/2）*（1/f）=（12/fose）*（216-x）即 x=2

3、 16-（fose/24f）其中，f是音調(diào)頻率，當(dāng)晶振fosc=11.0592MHz時(shí)，音節(jié)“ 1”相應(yīng)的定時(shí)器初 值為x，則可得到x=63777D=F921H其它的可同樣得到。表（1）音節(jié)與頻率的關(guān)系音調(diào)頻率（Hz）X(HEX)1262F9212294F9E13330FA8C4349FAD85392FB686440FBE97494FC5B在編寫歌曲代碼過程中，音高由三位數(shù)字組成：個(gè)位是表示17這七個(gè)音符；十位是表示音符所在的音區(qū)：1-低音，-中音，-高音；百位表示這個(gè)音符是 否要升半音：0-不升，-升半音。音長最多由三位數(shù)字組成：個(gè)位表示音符的時(shí) 值，其對(duì)應(yīng)關(guān)系是：| 數(shù)值(n): |0 |

4、1 |2 |3 | 4 | 5 | 6| 幾分音符：|1 |2 |4 |8 |16 |32 |64音符=2An十位表示音符的演奏效果(0-2): 0- 普通，-連音，-頓音，百位是符點(diǎn)位：0- 無符點(diǎn)，1-有符點(diǎn)。2 鍵盤掃描將單片機(jī)P1.0P1.7(引腳18)與鍵盤上對(duì)應(yīng)引腳相連，其中P1.0P1.3控制 鍵盤的行，P1.4P1.7控制鍵盤的列，這次使用的鍵盤是 4行4列，鍵盤上的第一 行到第四行由8位十六進(jìn)制代碼的低四位控制，即第一行若有鍵按下，則 8位十六 進(jìn)制代碼的后四位為0x8,第二行有按鍵按下，則后四位代碼為0x4,依此規(guī)律類 推；鍵盤上的第一列到第四列由8位十六進(jìn)制代碼的高四位控

5、制，即第一列若有 鍵按下，則8位十六進(jìn)制代碼的前四位為0x8,第二列有按鍵按下，則前四位代碼 為0x4,依此規(guī)律類推。綜上所述，可以根據(jù)8位十六進(jìn)制的高四位和低四位數(shù)據(jù)， 分別確定按下的鍵處于第幾行第幾列，從而確定按鍵的位置，實(shí)現(xiàn)鍵盤掃描的功 能。3. LCD顯示根據(jù)寫命令函數(shù)wrcomd和寫數(shù)據(jù)函數(shù)wrdata分別控制LCD的命令寫入和數(shù) 據(jù)寫入。具體操作方法是由寫命令函數(shù)wrcomd編程控制數(shù)據(jù)輸入的行列，再由寫數(shù)據(jù)函數(shù)wrdata編程寫入需要在LCD上顯示的數(shù)據(jù)或應(yīng)執(zhí)行的操作，結(jié)合兩 個(gè)命令一起控制LCD顯示。四.產(chǎn)品展示五.實(shí)驗(yàn)程序#ifndef _DRIVEFUTION_H_ #de
