more time before WWDG activation

[MMath.10]

Hi,

I use WWDG for my project.

That work great in error case but i have some spontaneous activation.

How can i configure WWDG to have a higher period?

here my init,

i'm i write to take WWDG_PRESCALER_8 instead of WWDG_PRESCALER_1?

/**
 * @brief WWDG Initialization Function
 * @param None
 * @retval None
 */
static void MX_WWDG_Init(void)
{
 
 /* USER CODE BEGIN WWDG_Init 0 */
 
 /* USER CODE END WWDG_Init 0 */
 
 /* USER CODE BEGIN WWDG_Init 1 */
 
 /* USER CODE END WWDG_Init 1 */
 hwwdg.Instance = WWDG;
 hwwdg.Init.Prescaler = WWDG_PRESCALER_8;
 hwwdg.Init.Window = 0x7F;
 hwwdg.Init.Counter = 0x7F;
 hwwdg.Init.EWIMode = WWDG_EWI_DISABLE;
 if (HAL_WWDG_Init(&hwwdg) != HAL_OK)
 {
 Error_Handler();
 }
 /* USER CODE BEGIN WWDG_Init 2 */
 
 /* USER CODE END WWDG_Init 2 */
 
}
