這個單片機最小系統播放音樂的例子真不錯

ID:73477 · 發表于 2015-2-10 20:16

學習單片機，制作單片機最小系統是每個單片機愛好者的都經歷過的階段，單片機最小系統制作好有什么用呢？為提高單片機愛好者學習制作單片機最小系統興趣，這里介紹一個有趣的單片機小程序，就是用單片機最小系統播放歡樂頌及最炫民族風片段。在按下圖制作好單片機最小系統后，再增加三只元件：1個電阻、1個S9012三極管，1個8歐的小喇叭后，即可完成這個單片機最小系統播放歡樂頌及最炫民族風片段的小試驗，單片機愛好者通過這個小試驗后，一定會大大增強對單片機學習的興趣。這個單片機最小系統播放歡樂頌及最炫民族風片段的小試驗，由于電路比較簡單，所以這里就不畫出原理圖了，直接給出試驗的PCB圖，感興趣的愛好者可以按圖進行焊接制作，制作好后向單片機內燒寫程序后安裝上去就可以工作，感受一下單片機的無窮勉力。

老師BUZZER取僅只用于常量，程序中有兩次賦值，到底是變量還是常量呀%

如果只是播放旋律而已的話，那么只要有你們想要播的歌曲的譜子，然后再懂得看譜子的話就可以編了。我一開始以為是播放全歌，認真看完之后才知道只是旋律。不過樓主已經好厲害了，寫的程序比較易懂。謝謝
