中断向量, flash, vi, NVIC, ic, ni

void NVIC_Configuration_TIM5(void)
{
  NVIC_InitTypeDef NVIC_InitStructure;
  NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x0000);
  NVIC_InitStructure.NVIC_IRQChannel = TIM5_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);

}
void NVIC_Configuration_RTC(void)
{
  NVIC_InitTypeDef NVIC_InitStructure;
  NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x0000);//这里的flash地址应该设置为多少这个我不知道怎么算  前面的TIM5 已经是从0000开始了
  NVIC_InitStructure.NVIC_IRQChannel = TIM5_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);
