stm32f103定时器中断、外部中断例子

bruce_li_lu

刚刚开始学习stm32f103的那个开发板，用的库是3.5的，现在想写一个定时器中断和外部中断的程序，但是历程里面都没有啊，完全没有头绪，有没有大神能解决一下呢。

基础例程中应该有

里面的基础例程都看过：
int main(void)
{
  RCC_Configuration();
  GPIO_Configuration();
  DMA_Configuration();

  /* TIM1 Peripheral Configuration --------------------------------------------*/
  /* Time Base configuration */
  TIM_TimeBaseStructure.TIM_Prescaler = 0;
  TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
  TIM_TimeBaseStructure.TIM_Period = 2000-1;//72M/x=frq R*C=0.025 R=100K,c=100000p=0.1uf=0.0000001f
  TIM_TimeBaseStructure.TIM_ClockDivision = 0;
  TIM_TimeBaseStructure.TIM_RepetitionCounter = 2;

  TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);

  /* Channel 3 Configuration in PWM mode */
  TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM2;
  TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
  TIM_OCInitStructure.TIM_OutputNState = TIM_OutputNState_Enable;
  TIM_OCInitStructure.TIM_Pulse = 50;
  TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_Low;
  TIM_OCInitStructure.TIM_OCNPolarity = TIM_OCNPolarity_Low;
  TIM_OCInitStructure.TIM_OCIdleState = TIM_OCIdleState_Set;
  TIM_OCInitStructure.TIM_OCNIdleState = TIM_OCIdleState_Reset;

  TIM_OC3Init(TIM1, &TIM_OCInitStructure);

  /* TIM1 Update DMA Request enable */
  TIM_DMACmd(TIM1, TIM_DMA_Update, ENABLE);

  /* TIM1 counter enable */
  TIM_Cmd(TIM1, ENABLE);

  /* Main Output Enable */
  TIM_CtrlPWMOutputs(TIM1, ENABLE);

  while (1)
  {}
}

void RCC_Configuration(void)
{
  SystemInit();

  /* TIM1, GPIOA and GPIOB clock enable */
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1 | RCC_APB2Periph_GPIOA |
                         RCC_APB2Periph_GPIOB, ENABLE);
  /* DMA clock enable */
  RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE);
}

void GPIO_Configuration(void)
{
  GPIO_InitTypeDef GPIO_InitStructure;

  /* GPIOA Configuration: Channel 3 as alternate function push-pull */
  GPIO_InitStructure.GPIO_Pin =  GPIO_Pin_10;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_Init(GPIOA, &GPIO_InitStructure);

  /* GPIOB Configuration: Channel 3N as alternate function push-pull */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_15;
  GPIO_Init(GPIOB, &GPIO_InitStructure);
}
定时器这样写是什么方式啊，不知道中断的话该怎么写

中断服务程序在 sm32f103_it.c 文件可以找到。

能说说怎么初始化配置吗，或者有个例程最好，灰常感谢
