我的基于单片机的公历转农历函数终于写出来了～

这段时间我都把精力投入到单片机编程开发上面，经常熬夜，有时感觉好累，又怕耽误了其他其他事情。最近一直在做一个基于单片机的超级万年历，用LCD12864作显示屏。虽然网上都有很多人做过了，但是我没做过，所以我也要做，要自己一个字一个字的的编写，不管是成功还是失败，这个过程总能让我学到很多东西，我认为。曾经在一个个网友的程序上面看到这个这么一句话：未曾尝试，就不能说失败。尝试对一个人的成长是很重要的。至少我前几天的努力就证明我尝试过了，也成功一大半了。万年历中的公历转农历的计算是个难点之一，现在我经过努力编写出来了，相信有信心有奋斗下去的勇气，接下来的工作会更成功的。

为了纪念我这次成功，我把这个公历转农历的函数放在这里，给自己的成长留点记印：

库名：gton.h
