分享一个好盈乐天电调初始化的经验 这是本人试出来的 希望对大家有帮助

信奉3

void Diantiao_Init(void)
{
 TIM_PrescalerConfig(TIM5,719,TIM_PSCReloadMode_Immediate);
 delay_ms(1000);  //延时1s
 TIM_Cmd(TIM5,DISABLE);
 delay_ms(500);//延时0.5s
 TIM_PrescalerConfig(TIM5, 1439,TIM_PSCReloadMode_Immediate);
 TIM_Cmd(TIM5,ENABLE);
}


static void PWM_Timer5_configuration(void)
{
    TIM_TimeBaseInitTypeDef TIM_TimeBaseInitStruct;
TIM_OCInitTypeDef TIM_OCInitStruct;

TIM_DeInit(TIM5);
TIM_TimeBaseInitStruct.TIM_ClockDivision = TIM_CKD_DIV4;  //???ù???¨?÷??·?????
    TIM_TimeBaseInitStruct.TIM_CounterMode    = TIM_CounterMode_Up;
TIM_TimeBaseInitStruct.TIM_Period         = 1000;    //PWM·???1000·?
TIM_TimeBaseInitStruct.TIM_Prescaler      =  719;       // ???ú????×???????????1KHZ  ??????????500HZ

    TIM_TimeBaseInit(TIM5,&TIM_TimeBaseInitStruct);

    TIM_OCInitStruct.TIM_OCMode       = TIM_OCMode_PWM1;
    TIM_OCInitStruct.TIM_OCPolarity  = TIM_OCPolarity_High;
    TIM_OCInitStruct.TIM_OutputState  = TIM_OutputState_Enable;
    TIM_OCInitStruct.TIM_Pulse        = 100;

    TIM_OC1Init(TIM5,&TIM_OCInitStruct);
TIM_OC2Init(TIM5,&TIM_OCInitStruct);
TIM_OC3Init(TIM5,&TIM_OCInitStruct);
    TIM_OC4Init(TIM5,&TIM_OCInitStruct);                                                                                       

    TIM_Cmd(TIM5,ENABLE);
    TIM_CtrlPWMOutputs(TIM5,ENABLE);
}

通过测试调速范围为50到100
