  * @brief LEDC get duty
+ *        This function returns the duty at the present PWM cycle.
+ *        You shouldn't expect the function to return the new duty in the same cycle of calling ledc_update_duty,
+ *        because duty update doesn't take effect until the next cycle.
  *
  * @param speed_mode Select the LEDC channel group with specified speed mode. Note that not all targets support high speed mode.
  * @param channel LEDC channel (0 - LEDC_CHANNEL_MAX-1), select from ledc_channel_t
