TIM6_DAC

TIM6_DAC_IRQn

guyii54 提问时间：2018-3-12 21:26 /

看到的例程里将这个定时器中断作为NVIC里管理的一个中断源进行配置，代码如下

#define BASIC_TIMx               TIM6
#define BASIC_TIMx_CLK       RCC_APB1Periph_TIM6

#define BASIC_TIMx_IRQn    TIM6_DAC_IRQn
#define BASIC_TIMx_IRQHandler TIM6_DAC_IRQHandler

static void TIMx_NVIC_Configuration(void)
{
NVIC_InitTypeDef NVIC_InitStructure;

NVIC_PriorityGroupConfig(NVIC_PriorityGroup_0);

NVIC_InitStructure.NVIC_IRQChannel = BASIC_TIMx_IRQn;

NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;

NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);
}

但是查找手册里NVIC里管理的中断并没有TIM6_DAC_IRQn这个定时器中断啊，帮助手册里NVIC_IRQChannel类型的枚举类型如下
