.c文件是驱动程序和C语言
.h文件是库文件，包含接口定义和函数声明
定义变量、定义函数都放在pbdata.h
函数体都放在pbdata.c
以下是pbdtada.h文件
如果之前没有定义过—pbdata—H函数
则定义—pbdata—H函数
·······················································································
以下是pbdtada.c文件
要在pbdata.c中输入#include“pbdata.h”引入pbdata.h文件
······················································································
例如：main.c文件中要引入#include“stm32f10x.h”STM32的头文件，才可以进行下一步操作，创建了自定义公共函数库pbdata，就可以将#include“stm32f10x.h”从main.c放置pbdata.h，仅在main.c中引入#include“pbdata.h”即可。
······················································································
引入头文件可以放在.h文件里
······················································································
例如：定义变量 定义函数
在.h里面定义变量、函数时，要加“；”
在.c里面添加函数体时，不需要加“；”
pbdata.h中
pbdata.c中
main.c中
