單片機音樂盒按鍵系統

① 單片機開發板有什麼用途

1、可以作為燒寫器（即編程器），將自己寫好的程序寫入單片機中，但燒寫單片機的種類單一 ，型號也不會太多。

2、可以利用開發板上的一些硬體做一些單片機實驗（不需要自己搭建實驗電路）有利於初學者使用。

單片機的學習需要理論和動手，理論與實踐並重。

單片機開發板介紹

單片機開發板是用於學習51、STC、AVR型號的單片機實驗設備。

根據單片機使用的型號又有51單片機開發板、STC單片機開發板、AVR單片機開發板。

常見配套有硬體、實驗程序源碼、電路原理圖、電路PCB圖等學習資料。

例如電子人單片機開發板，針對部分學者需要特別配套有VB上位機軟體開發,游戲開發等教程學習資料，開發此類單片機開發板的公司一般提供完善的售後服務與技術支持。

④ 想在單片機中燒一首歌(MP3）做音樂盒 需要哪些器材 怎麼做

呃，。。

這個比較復雜，
存在的問題如下：

1.一般的單片機的容量有限，幾K到幾十K甚至上百K不等，而一首MP3一般要幾M大小。。。這個差距你也能看的出來。。。除非外擴存儲空間，比如說flash，比如說SD卡之類的。。。

2.MP3是壓縮格式，按你說的做成音樂盒的話，肯定要解壓縮，一般的單片機的RAM也很有限，運算速度也很一般，軟解碼的話不現實；除非選擇硬解碼，這樣的話就要外加晶元。。。

再這樣分析下去估計你做成的就不是一個音樂盒了，而是一款「MP3」了。。。

生活中常見的那些會唱歌的玩具呀，短暫錄音的喇叭呀，汽車上那種「倒車請注意」或者語音報站之類的東西呀，都不是用你想像的方案實現的，用的是專門的語音錄制晶元。。。

當然，也可能是在下的見識有限，沒有接觸過能實現你這個要求的方案，

還有就是有個「凌陽」的單片機，似乎在語音方面比較擅長（本人也沒用過，不敢妄斷），你可以在網上了解一下。

希望以上回答能對你有所幫助。

我想知道你還想了解哪方面的？

⑤ 單片機音樂盒MOV DPTR,#DAT ;表頭地址送DPTR 怎樣送

如：MOV DPTR,#07EE
MOV @DPTR #0056
的意思是把立即數（DAT）送到DPTR中，其中DPH是高8位，DPL是低8位，
然後DPTR的內容作為地址，就是將0056送到07EE這個單元中。懂了么，不懂的話， 可以找我，QQ：309570317
