我将两个外部IO口分别是GPIOG的10脚和14脚设置为下降沿中断
RCC_APB2PeriphClockCmd( RCC_APB2Periph_GPIOG | RCC_APB2Periph_AFIO, ENABLE);
EXTI_InitStructure.EXTI_Line = GPIO_Pin_14;
EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;
EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Falling;
EXTI_InitStructure.EXTI_LineCmd = ENABLE;
EXTI_Init(&EXTI_InitStructure);
EXTI_InitStructure.EXTI_Line = GPIO_Pin_10;
EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;
EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Falling;
EXTI_InitStructure.EXTI_LineCmd = ENABLE;
EXTI_Init(&EXTI_InitStructure);
/* Enable the EXTI15_10 Interrupt */
NVIC_InitStructure.NVIC_IRQChannel = EXTI15_10_IRQChannel;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 14;
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);
现在的现象是，只能进入14脚的外部中断，10脚的中断怎么也进不去了 |
