单片机IO口播放乐曲，// 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] //
// 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 //
//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 //
//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//
//同时人工将音符译为机器码非常容易。-Single-chip IO I play music,// single-chip microcomputer used in the IO port T1 interrupt output music P1.0 [P1.0 port with VCC in an indirect one speaker can be heard]//// 1. Because of the output are square-wave, more bluntly :-] You can also be broken down by DA output waveform sine wave//// 2. because of the frequent interruption of T1, any other interruption will happen Dayton are playing music, is only suitable for test//// 3. Optimize coding notes: A byte contains rhythms, notes, take-off and landing tune can distinguish between data and command//// At the same time manually translated into binary notes very easily.
