2、）工作原理及設(shè)計(jì)思路音節(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，只要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/0 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 I/O 腳得到此頻率的方波。 在 ZKS-03實(shí)驗(yàn)儀上，產(chǎn)生方波的 I/O 腳選用 P1.7，通過(guò)跳線選擇器 JP1 將單片機(jī) 的 P1.7 與蜂鳴器的驅(qū)動(dòng)電路相連。 這樣 P1.7 輸出不同頻率的方波， 蜂鳴器便會(huì) 發(fā)出不同的聲音。另外，音樂(lè)的節(jié)拍是由延時(shí)實(shí)現(xiàn)的，如果 1 拍為 0.4 秒，

3、1/4 拍是 0.1 秒。只要設(shè)定延時(shí)時(shí)間， 就可求得節(jié)拍的時(shí)間。 延時(shí)作為基本延時(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 X 可按下法計(jì)算：（1/2 ）*（1/f）=（12/fose）*（216-x）即 x=216-（fose/24f）其中 f: 音調(diào)頻率，當(dāng)晶振 fose=11.0592MHz 時(shí)，音節(jié)“ 1”相應(yīng)的定時(shí)器初值為 x, 則可得 x=63777D=F921H其 它的可同樣求得。表1音調(diào)頻率（ Hz）X(HEX)1262F9212294F9E13330FA8C4349FAD85392FB686440FBE97494FC5Bi523FC8F四）實(shí)現(xiàn)功能設(shè)計(jì)實(shí)現(xiàn)兩
