最近在调试步进电机控制程序，利用STM32F407的timer10的第一通道，但是我写的程序，电机一直在运行，不能够停止，各路大神帮我看看，如何控制电机运行的圈数啊，谢谢各位，在线等
附代码：
void Tim10_Configuration(void)//PF6-CH1-T10 { TIM_TimeBaseInitTypeDef  TIM_TimeBaseStructure; TIM_OCInitTypeDef  TIM_OCInitStructure; RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM10, ENABLE);
TIM_DeInit(TIM10);
/*TIM10时钟配置*/ TIM_TimeBaseStructure.TIM_Prescaler = 5;    // TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;    // TIM_TimeBaseStructure.TIM_Period = 0xffff; // TIM_TimeBaseStructure.TIM_ClockDivision = 0; TIM_TimeBaseInit(TIM10,&TIM_TimeBaseStructure);
/* Channel 1 Configuration in oc mode */ TIM_OCStructInit(&TIM_OCInitStructure); TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Toggle; // TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;    // TIM_OCInitStructure.TIM_Pulse = S_50HZ;    // TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;     TIM_OC1Init(TIM10,&TIM_OCInitStructure);    //通道1 TIM_ClearFlag(TIM10, TIM_FLAG_CC1); TIM_ITConfig(TIM10, TIM_IT_CC1, DISABLE);
TIM_Cmd(TIM10,DISABLE); TIM_CtrlPWMOutputs(TIM10,ENABLE); TIM_ARRPreloadConfig(TIM10, DISABLE); }
void TIM10_CC_IRQHandler(void) {     uint16_t capture=0;   uint16_t  temp=0;  if(TIM_GetITStatus(TIM1, TIM_IT_CC1) == SET)     {         TIM_ClearITPendingBit(TIM10, TIM_IT_CC1 );   Tulun_i++;   if(Tulun_i == 10 )   {   TIM_Cmd(TIM10,DISABLE);   TIM_ITConfig(TIM10, TIM_IT_CC1, DISABLE); TIM_CtrlPWMOutputs(TIM10,DISABLE);   } } }
