/**

static void MX_TIM1_Init(void)
{
          
   

  /* USER CODE BEGIN TIM1_Init 0 */

  /* USER CODE END TIM1_Init 0 */

  TIM_Encoder_InitTypeDef sConfig = {
          
   0};

  htim1.Instance = TIM1;

  htim1.Init.CounterMode = TIM_COUNTERMODE_UP;
  htim1.Init.Period = 65535;
  htim1.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
  htim1.Init.RepetitionCounter = 0;
  htim1.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE;
  sConfig.EncoderMode = TIM_ENCODERMODE_TI1;
  sConfig.IC1Polarity = TIM_ICPOLARITY_RISING;
  sConfig.IC1Selection = TIM_ICSELECTION_DIRECTTI;
  sConfig.IC1Prescaler = TIM_ICPSC_DIV1;
  sConfig.IC1Filter = 0;
  sConfig.IC2Polarity = TIM_ICPOLARITY_RISING;
  sConfig.IC2Selection = TIM_ICSELECTION_DIRECTTI;
  sConfig.IC2Prescaler = TIM_ICPSC_DIV1;
  sConfig.IC2Filter = 0;
  if (HAL_TIM_Encoder_Init(&htim1, &sConfig) != HAL_OK)
  {
          
   
    Error_Handler();
  }
  sMasterConfig.MasterOutputTrigger = TIM_TRGO_RESET;
  sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;
  if (HAL_TIMEx_MasterConfigSynchronization(&htim1, &sMasterConfig) != HAL_OK)
  {
          
   
    Error_Handler();
  }
  /* USER CODE BEGIN TIM1_Init 2 */

  /* USER CODE END TIM1_Init 2 */

}

//个人认为这种打开编码器中断有可能有问题
__HAL_TIM_ENABLE_IT（&htimer,TIM_IT_UPDATE）;
 /* 野火提示 ： 设置更新事件请求源为：计数器溢出 这个地方可能会忘记设置 */
  __HAL_TIM_URS_ENABLE(&TIM_EncoderHandle);

骄阳的板子特别注明设置URS的位置，但是个人觉得不需要设置

__HAL_TIM_URS_ENABLE(&TIM_EncoderHandle);

//打开编码器
HAL_TIM_Encoder_Start(&htim, uint32_t Channel)
//打开更细中断
__HAL_TIM_ENABLE_IT（&htimer,TIM_IT_UPDATE）;
