我的想法是，按下按键通过AWD唤醒，我按照例程配置不知道为什么没有唤醒

/*IO初始化*/
void ADC_EXTI_GPIO_Configuration(void)
{
GPIO_InitTypeDef GPIO_InitStructure;

RCC_AHBPeriphClockCmd( RCC_AHBPeriph_GPIOC, ENABLE );
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC ,ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG ,ENABLE);

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_4 ;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AN;
GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL ;
  GPIO_Init(GPIOC, &GPIO_InitStructure);
GPIO_PinAFConfig(GPIOC,GPIO_PinSource4,GPIO_AF_7);
//PC3用于触发
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_3 ;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz;
  GPIO_Init(GPIOC, &GPIO_InitStructure);
GPIO_PinAFConfig(GPIOC,GPIO_PinSource3,GPIO_AF_7);

}

/*ADC配置*/

请问你用的什么烧录工具 stlink 吗
