单片机音乐盒按键系统

① 单片机开发板有什么用途

1、可以作为烧写器（即编程器），将自己写好的程序写入单片机中，但烧写单片机的种类单一 ，型号也不会太多。

2、可以利用开发板上的一些硬件做一些单片机实验（不需要自己搭建实验电路）有利于初学者使用。

单片机的学习需要理论和动手，理论与实践并重。

单片机开发板介绍

单片机开发板是用于学习51、STC、AVR型号的单片机实验设备。

根据单片机使用的型号又有51单片机开发板、STC单片机开发板、AVR单片机开发板。

常见配套有硬件、实验程序源码、电路原理图、电路PCB图等学习资料。

例如电子人单片机开发板，针对部分学者需要特别配套有VB上位机软件开发,游戏开发等教程学习资料，开发此类单片机开发板的公司一般提供完善的售后服务与技术支持。

④ 想在单片机中烧一首歌(MP3）做音乐盒 需要哪些器材 怎么做

呃，。。

这个比较复杂，
存在的问题如下：

1.一般的单片机的容量有限，几K到几十K甚至上百K不等，而一首MP3一般要几M大小。。。这个差距你也能看的出来。。。除非外扩存储空间，比如说flash，比如说SD卡之类的。。。

2.MP3是压缩格式，按你说的做成音乐盒的话，肯定要解压缩，一般的单片机的RAM也很有限，运算速度也很一般，软解码的话不现实；除非选择硬解码，这样的话就要外加芯片。。。

再这样分析下去估计你做成的就不是一个音乐盒了，而是一款“MP3”了。。。

生活中常见的那些会唱歌的玩具呀，短暂录音的喇叭呀，汽车上那种“倒车请注意”或者语音报站之类的东西呀，都不是用你想象的方案实现的，用的是专门的语音录制芯片。。。

当然，也可能是在下的见识有限，没有接触过能实现你这个要求的方案，

还有就是有个“凌阳”的单片机，似乎在语音方面比较擅长（本人也没用过，不敢妄断），你可以在网上了解一下。

希望以上回答能对你有所帮助。

我想知道你还想了解哪方面的？

⑤ 单片机音乐盒MOV DPTR,#DAT ;表头地址送DPTR 怎样送

如：MOV DPTR,#07EE
MOV @DPTR #0056
的意思是把立即数（DAT）送到DPTR中，其中DPH是高8位，DPL是低8位，
然后DPTR的内容作为地址，就是将0056送到07EE这个单元中。懂了么，不懂的话， 可以找我，QQ：309570317
