27 //描 述: 单片机利用T1中断在IO口P1.0输出乐曲 //
28 //--------------------------------------------------------------------------//
29 //说 明: //
30 // 单片机用T1中断在IO口P1.0输出乐曲(在P1.0口与VCC间接一喇叭即可听到) //
31 // 1.由于输出的是方波，比较难听:-)你也可以将波形细分用DA输出正弦波 //
32 // 2.由于T1频繁中断，任何其他中断发生都会是乐曲打顿，只适合试验 //
33 // 3.优化音符编码：一个字节中包含节拍、音符、升降调，可区分数据和命令//
34 // 同时人工将音符译为机器码非常容易。(格式看下面实例)//
35 //--------------------------------------------------------------------------//
36
37 //音符码格式:| D7 |D6 D5 D4| D3 |D2 D1 D0|
38 // |变调| 节拍|升降| 音符 |
39
40 //功能码格式:| D7 D6 D5 D4 | D3 D2 D1 D0|
41 // |高4位=0时是功能码|根据低4位散转 |
42 //最后字节为功能码必须==0x00退出
