求助各位大神，怎么用STC12C5A60S2的蜂鳴器放音樂(lè)啊，雖然有學(xué)過(guò)C語(yǔ)言，但是看到好多類似的單片機(jī)程序還是一臉蒙蔽。。。頭一次接觸單片機(jī)。謝謝各位大神了

通過(guò)控制蜂鳴器的開關(guān)時(shí)間來(lái)生成調(diào)子，網(wǎng)上有很多蜂鳴器的曲譜，改改用就好了

從網(wǎng)上直接搜索例程，現(xiàn)在這種做蜂鳴器的很簡(jiǎn)單

給你一個(gè)例程看看。

先讀通單片機(jī)原理，C語(yǔ)言再好只是語(yǔ)言好，與懂不懂單片機(jī)無(wú)關(guān)！

利用IO口輸出PWM波來(lái)驅(qū)動(dòng)三極管，從而驅(qū)動(dòng)蜂鳴器，曲子的話，網(wǎng)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(jī)中運(yùn)行看看看看效果咋樣。
