蜂鸣器实验-音乐程序。单片机用T0中断在IO口P1.5输出乐曲

1.由于输出的是方波，比较难听:-)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 使用晶振12M-Buzzer experiment- music program. Microcontroller IO port P1.5 T0 interrupt output music

1 Since the output is a square wave, more bluntly :-) can output sine waveform segments with DA

2 Because T1 frequently interrupted by any other interrupt occurs Dayton will be playing music, only for test use crystal 12M
