求问电机编码器解码函数怎么配置

a853

HAL_StatusTypeDef HAL_TIM_Encoder_Init(TIM_HandleTypeDef *htim,  TIM_Encoder_InitTypeDef* sConfig);
HAL_StatusTypeDef HAL_TIM_Encoder_DeInit(TIM_HandleTypeDef *htim);
void HAL_TIM_Encoder_MspInit(TIM_HandleTypeDef *htim);
void HAL_TIM_Encoder_MspDeInit(TIM_HandleTypeDef *htim);
/* Blocking mode: Polling */
HAL_StatusTypeDef HAL_TIM_Encoder_Start(TIM_HandleTypeDef *htim, uint32_t Channel);
HAL_StatusTypeDef HAL_TIM_Encoder_Stop(TIM_HandleTypeDef *htim, uint32_t Channel);
/* Non-Blocking mode: Interrupt */
HAL_StatusTypeDef HAL_TIM_Encoder_Start_IT(TIM_HandleTypeDef *htim, uint32_t Channel);
HAL_StatusTypeDef HAL_TIM_Encoder_Stop_IT(TIM_HandleTypeDef *htim, uint32_t Channel);
/* Non-Blocking mode: DMA */
HAL_StatusTypeDef HAL_TIM_Encoder_Start_DMA(TIM_HandleTypeDef *htim, uint32_t Channel, uint32_t *pData1, uint32_t *pData2, uint16_t Length);
HAL_StatusTypeDef HAL_TIM_Encoder_Stop_DMA(TIM_HandleTypeDef *htim, uint32_t Channel);


求问大佬这几个函数怎么用；电机解码的配置步骤。
