HAL WWDG types migration ¶

HAL WWDG callback ID type definition ¶

HAL1	HAL2
typedef enum { HAL_WWDG_EWI_CB_ID, HAL_WWDG_MSPINIT_CB_ID } HAL_WWDG_CallbackIDTypeDef;	Removed. Note The callback registration in HAL2 is handled by specific functions for each WWDG event. See HAL WWDG Callback Register Functions for more details. HAL_WWDG_MSPINIT_CB_ID is removed because the function HAL_WWDG_MspInit is removed.

HAL WWDG initialization type definition ¶

In HAL2, the WWDG_InitTypeDef structure has been deleted. The prescaler, window, and counter values are now calculated using private functions.

HAL1	HAL2
typedef struct { uint32_t Prescaler; uint32_t Window; uint32_t Counter; uint32_t EWIMode } WWDG_InitTypeDef;	Removed, The values of prescaler, window, counter, and the early wakeup interrupt mode are now calculated and configured based on the input parameters of the function HAL_WWDG_Start().

HAL1

HAL2

                typedef struct
{
    uint32_t Prescaler;
    uint32_t Window;
    uint32_t Counter;
    uint32_t EWIMode
} WWDG_InitTypeDef;

               

                Removed,
The values of prescaler, window, counter, and the early wakeup interrupt
mode are now calculated  and configured based on the input parameters of
the function  HAL_WWDG_Start().

               

HAL WWDG handle type definition ¶

In HAL2, the HAL WWDG handle structure has been renamed from WWDG_HandleTypeDef to hal_wwdg_handle_t.

HAL1	HAL2
WWDG_HandleTypeDef	hal_wwdg_handle_t

HAL WWDG callback type definition ¶

HAL1	HAL2
pWWDG_CallbackTypeDef	hal_wwdg_cb_t
