【正文】 3． 最后要提一點(diǎn)建議，希望下一次課程設(shè)計(jì)中，每個(gè)人都能有一塊實(shí)驗(yàn)開(kāi)發(fā)板，這樣能使每個(gè)人都能得到充分的鍛煉！六、參考文獻(xiàn)[1]徐泳龍. 單片機(jī)原理及應(yīng)用. 機(jī)械工業(yè)出版社 [2]曹天漢. 單片機(jī)原理與接口技術(shù). 電子工業(yè)出版社 [3]張有德，趙志英，涂時(shí)亮. 單片微型機(jī). 復(fù)旦大學(xué)出版社25。2． 在一個(gè)好的氛圍里才能踏下心來(lái)做東西，在這幾天課設(shè)的時(shí)間里，實(shí)驗(yàn)室的氛圍對(duì)我們的影響很大，大家一起努力，這也是我們能完成課設(shè)的動(dòng)力。d. 改進(jìn)方案：若采用可以定時(shí)時(shí)間更長(zhǎng)的單片機(jī)，可以避免所有問(wèn)題。b. 當(dāng)音樂(lè)為全4拍起始時(shí)，此時(shí)音樂(lè)節(jié)奏與定時(shí)器T1中斷頻率錯(cuò)開(kāi)，LCD顯示和音樂(lè)播放都會(huì)好一些。解決辦法：將定時(shí)器1設(shè)定在工作方式1，16位計(jì)數(shù)，計(jì)50ms,效果有很大改觀。6． 編程前要加流程圖，這樣會(huì)使思路清晰，例如數(shù)字音樂(lè)盒的設(shè)計(jì)思路完全可以按著MP3的工作方式列寫流程圖。4． 編程過(guò)程中要注意加注釋或分割線，否則，在程序過(guò)長(zhǎng)時(shí)容易變得很亂，不便于查找或更改。當(dāng)用JNZ指令時(shí)，跳轉(zhuǎn)范圍比較少，這時(shí)要用一個(gè)標(biāo)號(hào)中轉(zhuǎn)。TABLE100: DB 02H,91H,0A1H,16H,21H,11H,0A6H,81H,0A1H,9CH,02H,91H,0A1H,16H,21H,31H,24H,21H,0A1H,11H,0A1H DB 9CH,02H,11H,21H,36H,32H,24H,21H,0A1H,11H,0A1H,9CH,02H,91H,0A1H,14H,11H,11H,21H,11H,0A4H,04H,04H,02H,0A1H,11H,0A1H,93H,92H DB 02H,61H,71H,0B4H,0B2H,0B1H,0B1H,76H,0B1H,71H,6CH,02H,61H,71H,0B6H,0B1H,0B1H,76H,0B1H,71H,6CH,02H,51H,61H,56H,61H,51H,54H,51H,0B1H,71H,0B1H DB 72H,62H,68H,02H,61H,51H,66H,62H,58H,0CH,02H,51H,41H,5FH DB 02H,91H,0A1H,16H,21H,11H,0A6H,81H,0A1H,9CH,02H,91H,0A1H,16H,21H,31H,24H,21H,0A1H,11H,0A1H DB 9CH,02H,11H,21H,36H,32H,24H,21H,0A1H,11H,0A1H,9CH,02H,91H,0A1H,14H,11H,11H,21H,11H,0A4H,04H,04H,02H,0A1H,11H,0A1H,93H,92H DB 02H,61H,71H,0B4H,0B2H,0B1H,0B1H,76H,0B1H,71H,6CH,02H,61H,71H,0B6H,0B1H,0B1H,76H,0B1H,71H,6CH,02H,51H,61H,56H,61H,51H,54H,51H,0B1H,71H,0B1H DB 66H,62H,54H,0B2H,71H,61H,6CH DB 00 END 實(shí)驗(yàn)控制流程圖如下：初始化變量及LCD接口初始化計(jì)數(shù)器T0,定時(shí)器T1LCD顯示英文歡迎字符等待按鍵，是否有按鍵？包括播放鍵，暫停鍵，停止鍵歌曲號(hào)及播放時(shí)間顯示在LCD上主程序開(kāi)始依據(jù)按鍵碼演奏對(duì)應(yīng)的歌曲YN使用說(shuō)明：鍵盤如下：0123456789ABCDEF按鍵功能說(shuō)明：1~A：十首歌曲C：上一首歌曲D：下一首歌曲E：歌曲暫停F：開(kāi)機(jī)畫面四、調(diào)試程序調(diào)試中出現(xiàn)的問(wèn)題及解決的辦法：1． 有時(shí)會(huì)出現(xiàn)程序一點(diǎn)錯(cuò)誤也沒(méi)有，但就是不能正常運(yùn)行的現(xiàn)象，最后我們發(fā)行是因?yàn)槌绦蛑杏械闹噶顣鴮懙貌灰?guī)范導(dǎo)致的，例如有的RET返回指令一定要按正確格式書寫或在兩行指令間最好不要留空行。第九首十年。TABLE80: DB 86H,92H,12H,22H,32H,52H,68H,63H,52H,34H,62H,0B2H,0B2H,62H,51H,61H,51H,31H,54H DB 62H,0B2H,0B2H,62H,52H,32H,52H,52H,51H,61H,51H,31H,34H,52H,62H,74H,32H,52H,52H,32H,21H,31H,21H,11H,24H DB 32H,52H,52H,32H,22H,12H,24H,32H,52H,52H,32H,62H,52H,61H,51H,31H,21H,21H,31H,21H,11H,1CH DB 21H,31H,22H,23H,31H,21H,18H,02H,0B2H,0BCH,0B4H,72H,61H,51H,72H,61H,71H,61H,51H,61H,71H,61H,6FH DB 86H,94H,12H,22H,32H,52H,64H,62H,51H,31H,52H,21H,31H,21H,33H,62H,0B2H,0B2H,62H,51H,61H,51H,31H,54H DB 62H,0B2H,72H,61H,51H,51H,61H,51H,31H,54H,61H,0B2H,72H,61H,51H,51H,61H,51H,31H,32H,21H,11H,32H,51H,61H,54H DB 02H,32H,24H,32H,52H,52H,32H,22H,31H,21H,11H,24H,32H,52H,62H,0B2H,72H,61H,51H,61H,51H,31H,32H,52H,52H,32H,62H DB 51H,31H,31H,21H,11H,91H,23H,31H,21H,1CH,12H,24H,32H,62H,51H,31H,34H,0B4H,72H,61H,51H,63H,71H,64H DB 0B2H,54H,72H,62H,71H,61H,54H,61H,51H,31H,21H,34H,73H,61H,54H,22H,32H,52H,22H,36H,52H,62H,61H,31H,32H,21H,11H,21H,11H,91H,81H DB 94H,52H,62H,52H,42H,32H,22H,32H,52H,0B4H,74H,64H,52H,61H,51H,41H,5CH,02H,52H,0B4H,74H,63H,51H,61H,51H,31H,21H DB 00。第七首世上只有媽媽好。TABLE60: DB 32H,22H,38H,02H,22H,32H,22H,18H,04H,92H,12H,24H,22H,32H,22H,12H,92H,92H,88H,04H,32H,22H DB 38H,02H,22H,32H,22H,18H,04H,92H,12H,24H,22H,32H,22H,21H,92H,12H,28H,04H,32H,22H DB 38H,02H,22H,32H,22H,18H,04H,92H,12H,24H,22H,32H,22H,12H,92H,91H,11H,88H DB 04H,32H,52H,58H,02H,52H,62H,52H,38H,04H,22H,22H,24H,22H,32H,22H,12H,92H,92H DB 12H,12H,1cH,08H,02H,52H,52H,62H,0b2H,72H,72H,62H,32H,22H,22H,22H DB 38H,02H,32H,32H,52H,64H,64H,02H,92H,32H,22H,28H,04H,32H,52H,52H,32H,54H,02H,0b4H,72H DB 62H,72H,34H,02H,62H,62H,72H,62H,52H,32H,22H,02H,32H,22H,32H DB 58H,02H,52H,52H,62H,0b2H,72H,72H,62H,32H,22H,22H,22H DB 38H,02H,32H,32H,52H,64H,64H,02H,92H,32H,22H,28H,04H,32H,52H,52H,32H,54H,02H,0b4H,72H DB 62H,72H,34H,02H,62H,62H,72H,62H,52H,32H,22H,02H,84H,92H,1cH DB 00。第五首《大海》。TABLE40: DB 88h,14h,24h,36H,42H,34H,14H,28H,14H,94H DB 1fH,88H,14H,24H,34H,32H,42H,54H,14H DB 46H,32H,54H,22H,32H,32H,22H,2CH,38H,54H,74H DB 76H,62H,68H,54H,52H,62H,74H,62H,52H,3fH DB 46H,42H,54H,64H,54H,
