標(biāo)題: 跪求一個完整的歌曲播放代碼的設(shè)計思路
哪位大佬能簡單的指導(dǎo)一下我啊,求個大致的思路想靠自己的能力制作出來,提升自己的電子技術(shù)水平！C語言！希望大佬幫幫孩子要求：

基于51單片機的代碼，主要I為C芯片：89C51/2、DAC0832
將歌曲先寫入89C52的存儲區(qū)域，再經(jīng)DAC0832輸出到放大電路驅(qū)動speak或者beep。

51hei論壇就有很多可參考的啊！
例如：

將歌曲轉(zhuǎn)換成頻率值存進數(shù)組，再用頻率值驅(qū)動喇叭，這樣做出來只有音調(diào)，而且89c52也存不了多長時間的音樂，想放音樂最好學(xué)學(xué)SD卡的使用
