標題: 求助。怎么用STC12C5A60S2的蜂鳴器放音樂
求助各位大神，怎么用STC12C5A60S2的蜂鳴器放音樂啊，雖然有學過C語言，但是看到好多類似的單片機程序還是一臉蒙蔽。。。頭一次接觸單片機。謝謝各位大神了

通過控制蜂鳴器的開關時間來生成調子，網上有很多蜂鳴器的曲譜，改改用就好了

從網上直接搜索例程，現在這種做蜂鳴器的很簡單

給你一個例程看看。

本實例利用無源蜂鳴器發出音樂聲音。
還用到了定時計數器0

先讀通單片機原理，C語言再好只是語言好，與懂不懂單片機無關！

利用IO口輸出PWM波來驅動三極管，從而驅動蜂鳴器，曲子的話，網上都能百度到的

謝謝各位，太感謝了

找到你需要的曲譜在稍微修改，在單片機中運行看看看看效果咋樣。
