这是我写的程序，但是这里显示找不到库函数。后来我在网上找了答案，有人说库函数写进了核心文件里，但是我在主函数文件里编译了核心文件还是不行。如果我要用这种库函数的形式写应该怎么做？




#include"stm32f10x.h"
#include"core_cm3.h"
#define unsigned char uchar
void RCC_Configuration()
{
   ErrorStatus a;
   RCC_HSEConfig(RCC_HSE_ON);
   a=RCC_WaitForHSEStartUp();
    if(a==SUCCESS);
   {
     RCC_HCLKConfig(RCC_SYSCLK_Div1);
     RCC_PCLK1Config(RCC_HCLK_Div2);
     RCC_PCLK2Config(RCC_HCLK_Div1);
     FLASH_SetLatency(FLASH_Latency_2);
     FLASH_PrefetchBufferCmd(FLASH_PrefetchBuffer_Enable);
     RCC_PLLConfig(RCC_PLLSource_HSE_Div1,RCC_PLLMul_9);
     RCC_PLLCmd(ENABLE);
     while(RCC_GetFlagStatus(RCC_FLAG_PLLRDY)==RESET);
     RCC_SYSCLKConfig(RCC_SYSCLKSource_PLLCLK);
     while(RCC_GetSYSCLKSource()!=0x08);
    }
   RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB,ENABLE);
  }
  void GPIO_Configuration()
  {
    GPIO_InitTypeDef a;
    a.GPIO_Pin=GPIO_Pin_All;
    a.GPIO_Speed=GPIO_Speed_50MHz;
    a.GPIO_Mode=GPIO_Mode_Out_PP;
    GPIO_Init(GPIOB,&a);
  }
  void SysTick_Configuration()
  {
    SysTick_CounterCmd(SysTick_Counter_Disable);
    SysTick_CLKSource(SysTick_HCLK_Div8);
    SysTick_CounterCmd(SysTick_Counter_Clear);
    SysTick_SetReload(9000000);
  }
   void Dealy_StsTick(uhar delay)
  {
    uchar i;
    for(i=0;i<delay;i++)
   {
      SysTick_CounterCmd(SysTick_Counter_Enable);
      while(SysTick_GteFlagStatus(SysTick_FLAGG_COUNT)==0);
      SysTick_CounterCmd(SysTick_Counter_Disable);
      SysTick_CounterCmd(SysTick_Counter_Clear);
    }
  }
int main(void)
{
    RCC_Configuration();
    GPIO_Configuration();
    while(1)
   {
      GPIO_WriteBits(GPIOB,GPIO_Pin_0,(BitAction)1-ReadOutputDataBit(GPIOB,GPIO_Pin_0));//&para;&Aacute;&Egrave;&iexcl;&micro;±&Ccedil;°&para;&Euml;&iquest;&Uacute;&Ouml;&cedil;&pound;&not;&Egrave;&raquo;&ordm;ó&Egrave;&iexcl;·&acute;.
      Delay_SysTick(1);
    }
  }


然后就报错了。

后来我又试着自己写了一个操作寄存器的程序(只有延时函数写的寄存器)，但写完后他提示我说找不到寄存器名的定义。然后我就彻底不知道怎么办了。

我没有用视屏中的那个SYSTEM文件夹里的程序，想自己写。请各路大神告诉我解决方法~~最好是寄存器和库函数的方法都说一下。谢谢 此帖出自小平头技术问答
