TIM_PrescalerConfig(TIM2, 35999, TIM_PSCReloadMode_Immediate); TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Timing;//这个地方就是改比较模式的 但是由于比较模式无论选哪个对于产生中断的作用是一样的,所以选TIMING都可以 TIM_OCInitStructure.TIM_Chan
当TIMx_CCR1=TIMx_CNT时,翻转OC1REF的电平。也就是toggle模式 程序如下: TIM_TimeBaseStructure.TIM_Period = 65535; TIM_TimeBaseStructure.TIM_Prescaler = 0; TIM_TimeBaseStructure.TIM_ClockDivision = 0; TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up; TIM_TimeBaseInit(TIM2, &TIM_...
TIM_OCMode_Toggle会每次都翻转,所以也形成一个PWM,而占空比只会是百分之五十,周期为参数period的两倍,频率为1/2,因为一个period只翻转一次!翻转是在CCRX=CNT时翻转,并不是CNT=ARR(ARR=TIM_TimeBaseStructure.TIM_Period)。 输出比较时候可以出发本身的比较/捕获中断与溢出中断,我用的CH4,开启了TIM_IT_CC4 |...
TIM_TimeBaseInitStructure.TIM_RepetitionCounter = 0x00; TIM_TimeBaseInit(TIM4,&TIM_TimeBaseInitStructure); TIM_ARRPreloadConfig(TIM4,ENABLE); TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Active;; //设置成什么模式都行。 TIM_OCInitStructure.TIM_Pulse= 1000; TIM_OCInitStructure.TIM_OCPolarity = TIM...
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Toggle; //设置定时器工作在翻转模式 TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable; TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High; //设置4个通道 比较寄存器值 TIM_OCInitStructure.TIM_Pulse = CCR1_Val; ...
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Toggle; TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable; TIM_OCInitStructure.TIM_Pulse = 15-1; //-计数是从0开始的,所以减1 TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_Low; /* Output Compare Toggle Mode configuration: Channel4 */ ...
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up; TIM_TimeBaseInit(TIM3, &TIM_TimeBaseStructure);//定时器基本配置 /* Output Compare Toggle Mode configuration: Channel1 */ TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Toggle;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up; TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure); TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Toggle; //管脚输出模式:翻转(TIM输出比较触发模式) TIM_OCInitStructure.TIM_Channel = TIM_Channel_1;...
TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure); 开启输出比较通道,设置输出比较模式为翻转模式,并配置NVIC,开启输出比较中断,配置输出比较通道: TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Toggle; TIM_OCInitStructure.TIM_Pulse = 500; TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable; ...
完成上述设置后，我们开启输出比较通道，并将输出比较模式设置为翻转模式。此外，还需要配置NVIC以开启输出比较中断，并进一步配置输出比较通道的相关参数。这些参数包括TIM_OCMode（设置为TIM_OCMode_Toggle），TIM_Pulse（设置为500），以及TIM_OutputState和TIM_OCPolarity等。通过这些步骤，我们成功地配置了时钟信号和...
