定时器1触发中断配置有问题，一直进入不了中断，麻烦大家帮我看看

krnfx

TIM_ITConfig(TIM1, TIM_IT_COM,  ENABLE);

TIM_ITConfig(TIM1,TIM_IT_Trigger ,  ENABLE);
 NVIC_InitTypeDef NVIC_InitStructure;
 NVIC_InitStructure.NVIC_IRQChannel = TIM1_TRG_COM_IRQn; 
 NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0; 
 NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1; 
 NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
 NVIC_Init(&NVIC_InitStructure);

你这只是配置了TIM1的优先级，你配置TIM1本身了没？

TIM_ITConfig(TIM2, TIM_IT_Update, ENABLE); 这句话你好像没有

krnfx

定时器2也要配置吗？TIM_ITConfig(TIM1, TIM_IT_Update, ENABLE); 加上后确实能进入中断了，但是波形是这样的

上面6路是PWM互补的波形，最下面是触发中断里面让LED取反，但是不知道是怎么触发的

定时器2不需要配置吗，配置定时器1就可以，我是直接复制例程的语句
