把stm32的库文件都添加进来，然后在main。c 中  加这个：#include "stm32f10x.h" 》。。然后就

/**********************   STM32F10x_CONF_H 文件当中 **********************/

是/* Includes ------------------------------------------------------------------*/
/* Uncomment the line below to enable peripheral header file inclusion */
/* #include "stm32f10x_adc.h" */
/* #include "stm32f10x_bkp.h" */

把用到的外设之类的注释删掉 选择添加就可以了》。。。。gpio的话，至少要选rcc和gpio这两个。
我用到了gpio  iic  usart spi nvic exti 所以选择的较多。。。当然多选了也是没关系的。
