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
-Single-chip microcomputer used in the IO port T1 interrupt output music P1.0 (P1.0 port with VCC in the indirect one can hear the speaker) 1. As the output is a square wave, more bluntly :-) You can also fine-waveform DA output sine wave with sub-2. Due to the frequent interruption of T1, any other interruption occurs Dayton will be playing music, is only suitable for test 3. optimized coding notes: A byte contains rhythms, notes, take-off and landing tune can distinguish between data and command
