今天学呼吸灯，发现里面用的是TIM3的update中断，就不明白它是什么意思了， @arg TIM_IT_Update: TIM update Interrupt source * @arg TIM_IT_CC1: TIM Capture Compare 1 Interrupt source
* @arg TIM_IT_CC2: TIM Capture Compare 2 Interrupt source
* @arg TIM_IT_CC3: TIM Capture Compare 3 Interrupt source
* @arg TIM_IT_CC4: TIM Capture Compare 4 Interrupt source
* @arg TIM_IT_COM: TIM Commutation Interrupt source
* @arg TIM_IT_Trigger: TIM Trigger Interrupt source
* @arg TIM_IT_Break: TIM Break Interrupt source
这几个有什么区别呢？ |
