（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.
