此源码程序主要用于单片机开发中，当我们需要对一些重要的数据进行保存时，我们一般会考虑将数据写入MMPROM中，如24c02中，此时这个程序可以供大家直接当做子程序调用，框架清晰，简单易懂！-This source is mainly used for microcontroller development process, when we need to save some important data, we generally consider to write data MMPROM, as 24c02, in which case the program can be directly used as a subroutine call for everyone, framework is clear, easy to understand!
