Function Documentation

void WWDG_DeInit ( void  )

Deinitializes the WWDG peripheral registers to their default reset values.

Parameters
None
Return values
None

Definition at line 138 of file stm32f4xx_wwdg.c.

+ Here is the call graph for this function:

void WWDG_EnableIT ( void  )

Enables the WWDG Early Wakeup interrupt(EWI).

Note
Once enabled this interrupt cannot be disabled except by a system reset.
Parameters
None
Return values
None

Definition at line 196 of file stm32f4xx_wwdg.c.

void WWDG_SetCounter ( uint8_t  Counter)

Sets the WWDG counter value.

Parameters
Counterspecifies the watchdog counter value. This parameter must be a number between 0x40 and 0x7F (to prevent generating an immediate reset)
Return values
None

Definition at line 208 of file stm32f4xx_wwdg.c.

void WWDG_SetPrescaler ( uint32_t  WWDG_Prescaler)

Sets the WWDG Prescaler.

Parameters
WWDG_Prescalerspecifies the WWDG Prescaler. This parameter can be one of the following values:
  • WWDG_Prescaler_1: WWDG counter clock = (PCLK1/4096)/1
  • WWDG_Prescaler_2: WWDG counter clock = (PCLK1/4096)/2
  • WWDG_Prescaler_4: WWDG counter clock = (PCLK1/4096)/4
  • WWDG_Prescaler_8: WWDG counter clock = (PCLK1/4096)/8
Return values
None

Definition at line 154 of file stm32f4xx_wwdg.c.

void WWDG_SetWindowValue ( uint8_t  WindowValue)

Sets the WWDG window value.

Parameters
WindowValuespecifies the window value to be compared to the downcounter. This parameter value must be lower than 0x80.
Return values
None
