【正文】 表示，若查表結(jié)果為0xff，則表示曲子終了；若查表結(jié)果為0x00，則產(chǎn)生相應(yīng)的停頓效果。根據(jù)計(jì)數(shù)次數(shù)就可算出計(jì)數(shù)初值。這可以用延時(shí)程序delay()來實(shí)現(xiàn)。通過子函數(shù)連續(xù)不斷的調(diào)用音樂代碼就產(chǎn)生了動(dòng)聽的音樂。圖1思路圖如圖1所示按鍵部分有三個(gè)鍵，根據(jù)count1的值來決定花樣燈的種類。播放音樂，及花樣燈均通過調(diào)用子程序來實(shí)現(xiàn)?？傮w設(shè)計(jì)電路，如圖2。圖3硬件圖4軟件設(shè)計(jì)根據(jù)設(shè)計(jì)要求及其原理繪制程序流程圖，如圖4，,根據(jù)流程圖，在Keil中編寫程序，并不斷編譯跟調(diào)試，直至沒有任何錯(cuò)誤和警告。程序見附錄2。在keil中生成HEX文件，裝入單片機(jī)中運(yùn)行，按key1可看到花樣燈閃爍，每按一次變化一種樣式。按key3可以同時(shí)關(guān)閉燈跟歌曲。6總結(jié)例如我對(duì)單片機(jī)的中斷系統(tǒng)就了解不夠深，這使得我在設(shè)計(jì)按鍵控制的時(shí)候，面臨很大的問題，最終我通過重新翻閱課本及相關(guān)資料，克服了這一困難。最終我通過向老師答疑得以解決。 總之可以說是收益匪淺。//按key1可切換花樣sbit key2=P3^3。//總開關(guān)，用于總體控制花樣燈跟歌曲。//蜂鳴器連續(xù)到I/O口P3^7上//六種花樣燈閃爍代碼uchar code huayang1[]={0x7f,0xbf,0xdf,0xef,0xf7,0xfb,0xfd,0xfe, 0xfd,0xfb,0xf7,0xef,0xdf,0xbf}。//花樣燈2uchar code huayang3[]={0x7f,0x3f,0x1f,0x0f,0x07,0x03,0x01,0x0, 0x80,0xc0,0xe0,0xf0,0xf8,0xfc,0xfe,0xff}。 //花樣燈4uchar code huayang5[]={0x3f,0xfc,0x9f,0xf9,0xcf,0xf3,0xe7, 0xcf,0xf3,0x9f,0xf9,0x3f,0xfc}。 //花樣燈6uchar count1。//歌曲標(biāo)志 uchar timeh,timel,i。字節(jié)低位控制該音調(diào)持續(xù)的時(shí)間，//代表多少個(gè)十六分音符。uchar code yldbwdx[]={ //月亮代表我的心0x02,0x82,0x16,0x32,0x54,0x02,0x52,0xA6,0x32,0x54,0x02,0x52,0x64,0x74,0xB6,0x64,0x52,0x5C,0x32,0x22,0x16,0x12,0x14,0x32,0x22,0x16,0x12,0x14,0x22,0x32,0x26,0x12,0x94,0x22,0x32,0x2C,0x32,0x52,0x36,0x22,0x14,0x54,0xAC,0x92,0xA2,0x96,0xA2,0x96,0x82,0x3C,0x54,0x36,0x22,0x14,0x54,0xAC,0x92,0xA2,0x16,0x12,0x14,0x22,0x32,0x2C,0x02,0x82,0x16,0x32,0x56,0x12,0xA6,0x32,0x56,0x52,0x66,0x72,0xB6,0x62,0x1C, 0xff//結(jié)束標(biāo)志}。uchar code lzh[]={//國歌0x03,0x04,0x04,0xc2,0x14,0x12,0x12,0x12,0x11,0x11,0xc2,0xd1,0xe1,0x14,0x02,0x32,0x12,0x21,0x31,0x52,0x51,0x51,0x54, 0x32,0x31,0x31,0x12,0x11,0x31,0x52,0x51,0x31,0x24,0x24,0x24,0x64,0x54,0x24,0x34,0x52,0x32,0x21,0x31,0x12,0x11,0x21,0x34,0x04, 0x52,0x51,0xd1,0x12,0x12,0x32,0x31,0x31,0x52,0x51,0x51,0x22,0x22,0x22,0xd2,0xd1,0x24,0x22,0xc2,0x14,0x12,0x34,0x32,0x32,0x54,0x54,0x54,0x54,0x12,0x11,0x31,0x52,0x51,0x51,0x64,0x54,0x32,0x31,0x11,0x52,0x52,0x52,0x32,0x02,0x12,0x02,0xc4,0x14,0xa2,0xa1,0x11,0x52,0x52,0x52,0x32,0x02,0x12,0x02,0xc4,0x14,0xc4,0x14,0xc4,0x14,0x14,0x04,0x04,0x04,0x04,0x04,0xff}。uchar code qnzl[]={ //千年之戀0x12,0x22,0x34,0x84,0x74,0x
