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.

（个人原创）这个是我在Keil下写的MAX5532--MAX5535通用的驱动代码，由于我编写的时候，考虑到通用性，所以当你使用的时候，需要根据你的器件特性几乎不用修改函数提来调用我的函数模块（我在需要调用的注释和注意点已经写的很清楚了），缩短你的工程开发周期。-(Personal original) This is what I wrote in under Keil GM MAX5532 MAX5535 driver code, as I am prepared when taking into account the general, so when you use when you need to almost do not modify the device characteristics mentioned function to call I have a function module (I need to call attention to the comments and points have been written very clearly), and shorten your project development cycle.
