HAL_StatusTypeDef HAL_WWDG_Init

(

WWDG_HandleTypeDef *

hwwdg

)

Initialize the WWDG according to the specified.

parameters in the WWDG_InitTypeDef of associated handle.

void HAL_WWDG_MspInit

(

WWDG_HandleTypeDef *

hwwdg

)

Initialize the WWDG MSP.

Parameters:

hwwdg

pointer to a WWDG_HandleTypeDef structure that contains the configuration information for the specified WWDG module.

Note:

When rewriting this function in user file, mechanism may be added to avoid multiple initialize when HAL_WWDG_Init function is called again to change parameters.

Return values:

None
