stm32l1xx_it.c中未定义TimingDelay_Decrement

八度空间 · 发表于 2014-5-14 10:09:08

TimingDelay_Decrement所在的头文件没加到stm32l1xx_it.c中或者stm32l1xx_it.h中

代码是：

#include "STM32L1xx.h"                  // Device header
#include "main.h"

void delay5ms(void)   //delay 500 us
{
unsigned char a,b;
for(b=71;b>0;b--)
  for(a=2;a>0;a--);
}

int main(void)
{
GPIO_InitTypeDef  GPIO_InitStructure;
/* GPIOD

eriph clock enable */
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOD, ENABLE);

/* Configure

D0 and

D1 or

D3 and

D7 in output pushpull mode */
   GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5;
   GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;
   GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;
   GPIO_InitStructure.GPIO_Speed = GPIO_Speed_40MHz;
   GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL;
   GPIO_Init(GPIOD, &GPIO_InitStructure);
GPIO_SetBits(GPIOB,GPIO_Pin_5);

  while(1)
{
  GPIO_ResetBits(GPIOB,GPIO_Pin_5);
//Delay(3000000);
delay5ms();
GPIO_SetBits(GPIOB,GPIO_Pin_5);
delay5ms();
//Delay(3000000);
}
}
