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-T1 chip Computer IO interruption in output P1.0 mouth music (P1.0 mouth with a loudspeaker indirectly VCC can be heard) / / / / 1. As the square wave output, more bluntly : -) You can also use sub-DA waveform output sine wave / / / / 2. As T1 frequently interrupted, any other interruption occurred will be playing music Kingston, it is only suitable for testing / / / / 3. Code optimization notes : a byte contains rhythms, musical notes, movements emphasize that can distinguish between data and orders
