各位專家您好，我在重映射TIM10的時候，無法輸出PWM

我的函數(shù)如下，請專家指導(dǎo)，謝謝。

void?stepper_pwm_init(?void)
{
????GPIO_InitTypeDef????????GPIO_InitStructure={0};
????TIM_OCInitTypeDef???????TIM_OCInitStructure={0};
????TIM_TimeBaseInitTypeDef?TIM_TimeBaseInitStructure={0};
????RCC_APB2PeriphClockCmd(?RCC_APB2Periph_GPIOE?|?RCC_APB2Periph_TIM10?|?RCC_APB2Periph_AFIO,?ENABLE?);
????GPIO_PinRemapConfig(GPIO_FullRemap_TIM10?,?ENABLE);
????GPIO_InitStructure.GPIO_Pin?=?GPIO_Pin_3|GPIO_Pin_4|GPIO_Pin_5;
????GPIO_InitStructure.GPIO_Mode?=?GPIO_Mode_AF_PP;
????GPIO_InitStructure.GPIO_Speed?=?GPIO_Speed_50MHz;
????GPIO_Init(?GPIOE,?&GPIO_InitStructure?);

#if?(PWM_MODE?==?PWM_MODE1)
????TIM_OCInitStructure.TIM_OCMode?=?TIM_OCMode_PWM1;
#elif?(PWM_MODE?==?PWM_MODE2)
????TIM_OCInitStructure.TIM_OCMode?=?TIM_OCMode_PWM2;

#endif

????TIM_OCInitStructure.TIM_OCPolarity?=?TIM_OCPolarity_High;
????TIM_OC1Init(?TIM10,?&TIM_OCInitStructure?);
????TIM_OC2Init(?TIM10,?&TIM_OCInitStructure?);
????TIM_OC3Init(?TIM10,?&TIM_OCInitStructure?);
????TIM_CtrlPWMOutputs(TIM10,?ENABLE?);
????TIM_OC1PreloadConfig(?TIM10,?TIM_OCPreload_Disable?);

????TIM_OC3PreloadConfig(?TIM10,?TIM_OCPreload_Disable?);
????TIM_ARRPreloadConfig(?TIM10,?ENABLE?);
????TIM_Cmd(?TIM10,?ENABLE?);
}

上面的程序不知道為什么輸入進(jìn)來帶有很多問

上面程序不知道為什么輸入很多問好，麻煩專家參考如下的程序

????TIM_Cmd(?TIM10,?ENABLE?);
}

您好，PE3、4、5是作為互補(bǔ)通道使用的，若要PWM輸出，配置使用獨(dú)立的比較捕獲通道即可，可以配置使用截圖圈出的引腳。

老師您好，非常感謝，根據(jù)指導(dǎo)，有一些進(jìn)展，現(xiàn)在 正向 PWM有輸出PD1-PD3-PD5閃爍， 但是負(fù)向的PWM還是沒變化，也就是PE3\PE4\PE5無變化，我的初始化程序如下，請您再指導(dǎo)下哈，謝謝。

您好，PE3、4、5是互補(bǔ)通道，程序中要進(jìn)行互補(bǔ)通道的配置，EVT有對應(yīng)的例程，可以參考一下。
