说明：  RTC芯片驱动 正点原子公众号 之前和大家分享了一下几个时钟芯片的驱动代码还有原理图什么的“发一个之前玩过的几个RTC芯片程序” 最近因为一个项目原因，全部更新了PCF8563这个芯片的驱动代码，主要是直接在函数设置BCD格式和BIN格式的转换输出，全部操作利用结构体的思路，更加清晰明了。
(RTC chip driver Before the punctuation atomic public number, I share with you some driving codes of several clock chips, as well as the schematic diagram of "a few RTC chip programs that have been played before". Recently, because of the reason of a project, all the driver codes of PCF8563 chip have been updated. The main function is to directly transform the output of BCD format and BIN format directly in function, and all operations are clear and clear by using the idea of structure.)
