STM32F051 TIM17产生两路带死区的互补pwm
我想用STM32F051 TIM17产生两路带死区的互补pwm，互补pwm出来了，但死区没有，不知道哪位大神有经验？TIM_TimeBaseStructure.TIM_Period = 4095;
TIM_TimeBaseStructure.TIM_Prescaler = 11485;//11719;
TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseStructure.TIM_RepetitionCounter = 0;
TIM_TimeBaseInit(TIM17, &TIM_TimeBaseStructure);
TIM_ARRPreloadConfig(TIM17, ENABLE);
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
TIM_OCInitStructure.TIM_Pulse = 1000;
TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_OutputNState = TIM_OutputNState_Enable;
TIM_OCInitStructure.TIM_OCNPolarity = TIM_OCNPolarity_High;
TIM_OCInitStructure.TIM_OCIdleState = TIM_OCIdleState_Set;
TIM_OCInitStructure.TIM_OCNIdleState = TIM_OCIdleState_Set;
TIM_OC1Init(TIM17, &TIM_OCInitStructure);
TIM_OC1PreloadConfig(TIM17, TIM_OCPreload_Enable);
TIM_BDTRInitStructure.TIM_OSSRState = TIM_OSSRState_Enable;
TIM_BDTRInitStructure.TIM_OSSIState = TIM_OSSIState_Enable;
TIM_BDTRInitStructure.TIM_LOCKLevel = TIM_LOCKLevel_OFF;
TIM_BDTRInitStructure.TIM_DeadTime = 500;
TIM_BDTRInitStructure.TIM_Break = TIM_Break_Disable;
TIM_BDTRInitStructure.TIM_BreakPolarity = TIM_BreakPolarity_Low;
TIM_BDTRInitStructure.TIM_AutomaticOutput = TIM_AutomaticOutput_Enable;
TIM_BDTRConfig(TIM17, &TIM_BDTRInitStructure);
TIM_ARRPreloadConfig(TIM17, ENABLE);
TIM_Cmd(TIM17, ENABLE);
TIM_CCPreloadControl(TIM17,ENABLE);
TIM_CtrlPWMOutputs(TIM17, ENABLE);
楼主你好，我在官方例程基础上跑了一下，发现死区时间的定义不是直接定义的。你再试试看:)
TIM_BDTRInitStructure.TIM_DeadTime = 500; 这个值太大了。
我用的设置是TIM_BDTRInitStructure.TIM_DeadTime = 11
