IAR软件main.c文件中函数先后组织次序，我一般将主函数放到最终，调用的函数放在上面。这样能够省去了被调函数的声明。

以GPIO为例，main.c中只需包括一个文件：stm32f10x_lib.h

这个看着比较了解，如同在哪见过，没错，在stm32f10x_map.h中就有这些界说，这便是为什么，在stm32f10x_config.h中将DEBUF宏界说注释起来时，也能编译曩昔的原因。






在stm32f10x_lib.h上右击鼠标，open “stm32f10x_lib.h”，该文件包括了其他一切头文件，而其他所需头文件主动参加。




标明符：_ADC，表明假如界说了_ADC，在stm32f10x_lib.h就包括stm32f10x_adc.h，不然，不包括stm32f10x_adc.h，那么，标明符_ADC是在哪界说的呢？是在stm32f10x_conf.h中界说的。

在stm32f10x_map.h上右击鼠标，open “stm32f10x_map.h”，翻开stm32f10x_map.h文件。


stm32f10x_map.h文件界说了一切外设的寄存器数据结构和存储器映像。

在stm32f10x_conf.h上右击鼠标，open “stm32f10x_conf.h”，翻开stm32f10x_conf.h文件。


stm32f10x_conf.h文件是项目装备头文件，该头文件设置了一切用到的外设，没有用到的外设能够将其屏蔽掉，以节约编译时刻。


提示：假如修正不了stm32f10x_conf.h文件时，是因为该文件是只读特点，在特点中修正即可。




注意到main函数中有






#ifdef DEBUG
debug();
#endif




这段代码，那么DEBUG标明符是在哪界说的呢？是在stm32f10x_conf.h中界说的。


还有，单片机的外部高速晶振HSE，不同的开发板能够有不同的值。那么HSE的值是在哪界说的呢？仍是在stm32f10x_conf.h中。
