求教，stm32f0 timer17 PWM不出问题

我只用1路PWM，用的是CH1N，可是就是不出，求大神帮忙看看啊。
void MX_TIM17_Init(void)
{
  TIM_BreakDeadTimeConfigTypeDef sBreakDeadTimeConfig;
  TIM_OC_InitTypeDef sConfigOC;
  htim17.Instance = TIM17;
  htim17.Init.Prescaler = 4799;
  htim17.Init.CounterMode = TIM_COUNTERMODE_UP;
  htim17.Init.Period = 4800;
  htim17.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
  htim17.Init.RepetitionCounter = 0;
  HAL_TIM_Base_Init(&htim17);

  HAL_TIM_PWM_Init(&htim17);
  sBreakDeadTimeConfig.OffStateRunMode = TIM_OSSR_DISABLE;
  sBreakDeadTimeConfig.OffStateIDLEMode = TIM_OSSI_DISABLE;
  sBreakDeadTimeConfig.LockLevel = TIM_LOCKLEVEL_OFF;
  sBreakDeadTimeConfig.DeadTime = 0;
  sBreakDeadTimeConfig.BreakState = TIM_BREAK_DISABLE;
  sBreakDeadTimeConfig.BreakPolarity = TIM_BREAKPOLARITY_HIGH;
  sBreakDeadTimeConfig.AutomaticOutput = TIM_AUTOMATICOUTPUT_DISABLE;
  HAL_TIMEx_ConfigBreakDeadTime(&htim17, &sBreakDeadTimeConfig);

  sConfigOC.OCMode = TIM_OCMODE_PWM2;
  sConfigOC.Pulse =2000;
  sConfigOC.OCPolarity = TIM_OCPOLARITY_HIGH;
  sConfigOC.OCNPolarity = TIM_OCNPOLARITY_LOW;
  sConfigOC.OCFastMode = TIM_OCFAST_DISABLE;
  sConfigOC.OCIdleState = TIM_OCIDLESTATE_RESET;
  sConfigOC.OCNIdleState = TIM_OCNIDLESTATE_RESET;
  HAL_TIM_PWM_ConfigChannel(&htim17, &sConfigOC, TIM_CHANNEL_1);
}

解决了，库有bug，自己添加相关参数解决

正点原子

帮顶....
