TIM1_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_Low;
TIM1_OCInitStructure.TIM_OCNPolarity = TIM_OCNPolarity_Low;
TIM1_OCInitStructure.TIM_OCIdleState = TIM_OCIdleState_Set;
TIM1_OCInitStructure.TIM_OCNIdleState = TIM_OCIdleState_Reset;
你这里定义的输出哦度是低有效，什么有定义的空闲状态又是一个高，一个低呢？这不冲突吗？
TIM1_BDTRInitStructure.TIM_AutomaticOutput = TIM_AutomaticOutput_Enable;
你这里为什么要使能自动输出呢？ |
