STM32标准库文件使用

1. stm32fxx.h

main.c 开头包含 

#include "stm32f2xx.h"

#include "stm322xg_eval.h"

#include "stm322xg_eval_lcd.h"

#include <stdio.h>

stm32f2xx.h开头有

#if !defined  (USE_STDPERIPH_DRIVER)

/**

 * @brief Comment the line below if you will not use the peripherals drivers.

   In this case, these drivers will not be included and the application code will 

   be based on direct access to peripherals registers 

   */

  /*#define USE_STDPERIPH_DRIVER*/

#endif /* USE_STDPERIPH_DRIVER */

stm32f2xx.h结尾有

#ifdef USE_STDPERIPH_DRIVER

  #include "stm32f2xx_conf.h"

#endif /* USE_STDPERIPH_DRIVER */

如果想使用标准库只需要去掉  /*#define USE_STDPERIPH_DRIVER*/前后的注释

stm32f2xx_conf.h中包含了各个外设标准库的头文件

#include "stm32f2xx_adc.h"

#include "stm32f2xx_can.h"

#include "stm32f2xx_crc.h"

#include "stm32f2xx_cryp.h"

#include "stm32f2xx_dac.h"
