2-3-1.`STM32F10x`固件库文件分析

在这里插入图片描述

1-汇编编写的启动文件
startup_stm32f10x_hd.s:设置堆栈指针、设置PC指针、初始化中断向量表、配置系统时钟、对用C库函数_main最终去到C的世界

2-时钟配置文件
system_stm32f10x.c：把外部时钟HSE=8M，经过PLL倍频为72M。

3-外设相关的
stm32f10x.h：实现了内核之外的外设的寄存器映射
xxx：GPIO、USRAT、I2C、SPI、FSMC
stm32f10x_xx.c：外设的驱动函数库文件
stm32f10x_xx.h：存放外设的初始化结构体，外设初始化结构体成员的参数列表，外设固件库函数的声明

4-内核相关的
CMSIS - Cortex 微控制器软件接口标准
core_cm3.h：实现了内核里面外设的寄存器映射
core_cm3.c：内核外设的驱动固件库

NVIC(嵌套向量中断控制器)、SysTick(系统滴答定时器)
misc.h
misc.c

5-头文件的配置文件
stm32f10x_conf.h：头文件的头文件
//stm32f10x_usart.h
//stm32f10x_i2c.h
//stm32f10x_spi.h
//stm32f10x_adc.h
//stm32f10x_fsmc.h
......

6-专门存放中断服务函数的C文件
stm32f10x_it.c
stm32f10x_it.h

中断服务函数你可以随意放在其他的地方，并不是一定要放在stm32f10x_it.c
#include "stm32f10x.h"   // 相当于51单片机中的  #include <reg51.h>

int main(void)
{
	// 来到这里的时候，系统的时钟已经被配置成72M。
}

2-8.配置魔术棒选项卡

在这里插入图片描述

在这个选项中添加宏，就相当于我们在文件中使用“#define”语句定义宏一样。在编译器中添加宏的好处就是，只要用了这个模版，就不用源文件中修改代码。
STM32F10X_HD宏：为了告诉STM32标准库，我们使用的芯片类型是大容量的，使STM32标准库根据我们选定的芯片型号来配置。
USE_STDPERIPH_DRIVER宏：为了让stm32f10x.h包含stm32f10x_conf.h这个头文件。
