定时器产生PWM信号，定时器没打开，PWM就产生了

cldz611

static void GENERALTIM_Mode_Config(void)
{

        GENERAL_TIM_APBxClock_FUN(GENERALTIM_CLK,ENABLE);
  TIM_TimeBaseInitTypeDef  TIM_TimeBaseStructure;
        TIM_TimeBaseStructure.TIM_Period=GENERAL_TIM_Period;               
        TIM_TimeBaseStructure.TIM_Prescaler= GENERAL_TIM_Prescaler;       
        TIM_TimeBaseStructure.TIM_ClockDivision=TIM_CKD_DIV1;               
        TIM_TimeBaseStructure.TIM_CounterMode=TIM_CounterMode_Up;               

        TIM_TimeBaseStructure.TIM_RepetitionCounter=0;       
        TIM_TimeBaseInit(GENERALTIM, &TIM_TimeBaseStructure);

        uint16_t CCR1_Val = 5;

        TIM_OCInitTypeDef  TIM_OCInitStructure;
        TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
        TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
        TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
        TIM_OCInitStructure.TIM_Pulse = CCR1_Val;
        TIM_OC1Init(GENERALTIM, &TIM_OCInitStructure);
        TIM_OC1PreloadConfig(GENERALTIM, TIM_OCPreload_Enable);
       
//         TIM_Cmd(GENERALTIM, DISABLE);
}

用通用寄存器产生PWM脉冲方波信号，可是我用初始化TIM_Cmd(GENERALTIM, DISABLE)，关闭寄存器，但是板子依然正常输出PWM信号？

我看你发了两个帖子，都是关不掉或是没开就有了，你debug一下，单步执行下看看什么时候TIM被使能了

在别的地方有使能TIM了，检查下代码有使能定时器的地方
