stc公司不错的单片机，适合小型应用，赶快下吧，-STC company Singlechip good for small applications, as soon as possible under the bar,

这个是我今天用Keil_C51写的关于MAX5417的底层函数，微控制器可以用其他的（我是用51的，其他的话，只要修改一下头文件就可以了），上层软件只要调用Write_MAX5417()这个函数就可以了，代码简洁，层次分明，注释也不少，非常适合新手学习或者是直接拿来为自己的上层软件服务。-This is what I write today with Keil_C51 on the bottom of MAX5417 function, microcontroller can use the other (I am using the 51 other words, as long as the modified header file you can), and the upper software as long as the call Write_MAX5417 () this function it, the code is simple and structured notes are also many, very suitable for novices to learn, or is directly used for their top software services.

单片机最小系统，两位LED数码管由串口输出接两个164驱动，Lout,Rout为左右声道输出，SET， ALT0， ALT1为三个按键，也可自己在开始的I/O定义改成你想用的I/O口；12M晶振若用89C51则只可装下约14首歌曲，用89C52则可装下近40曲-smallest SCM system, two LED digital serial output from the pipe then two 164-driven, Lout, Rout for about channel output, SET, ALT0, ALT1 to three keys, but also his own in the beginning I/O definition you want to change the I/O port; If using crystal 12M 89C51 can carry only about 14 songs, can be loaded with 89C52 Near 40
