TB6560步进电机驱动不了

andy741520 · 发表于 2017-3-16 16:42:29

自己尝试写了个PWM程序想要让电机动起来，上网查了些资料后，想自己尝试下驱动TB6560步进电机。
但是并不成功，想请教一下各位哪里出了问题，希望可以得到一些建议。
以下是接线

接着是程序
void TIM1_PWM_Init(void)
{
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
TIM_OCInitTypeDef TIM_OCInitStructure;
GPIO_InitTypeDef GPIO_Initstructure;

RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA,ENABLE);

GPIO_Initstructure.GPIO_Mode=GPIO_Mode_AF_PP;
GPIO_Initstructure.GPIO_Pin=GPIO_Pin_8;
GPIO_Initstructure.GPIO_Speed=GPIO_Speed_50MHz;
GPIO_Init(GPIOA,&GPIO_Initstructure);

TIM_TimeBaseStructure.TIM_Prescaler = 720-1;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseStructure.TIM_Period = 1000-1;
TIM_TimeBaseStructure.TIM_ClockDivision = 0;
TIM_TimeBaseStructure.TIM_RepetitionCounter = 0;
TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);

TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM2;
TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_OutputNState = TIM_OutputNState_Disable;
  TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_Low;
TIM_OCInitStructure.TIM_OCNPolarity = TIM_OCNPolarity_High;
TIM_OCInitStructure.TIM_OCIdleState = TIM_OCIdleState_Set;
TIM_OCInitStructure.TIM_OCNIdleState = TIM_OCIdleState_Reset;

TIM_OC1Init(TIM1, &TIM_OCInitStructure);
TIM_OC2Init(TIM1, &TIM_OCInitStructure);
TIM_OC3Init(TIM1, &TIM_OCInitStructure);
TIM_OC4Init(TIM1, &TIM_OCInitStructure);

TIM1->CCR1 = 0;

TIM_CtrlPWMOutputs(TIM1, ENABLE);
TIM_Cmd(TIM1,ENABLE);

}

int main()
{
while(1)
{
      GPIO_SetBits(GPIOB, GPIO_Pin_5);
      GPIO_SetBits(GPIOB, GPIO_Pin_6);
      TIM_SetCompare1(TIM1,600);
}
}
