Function Documentation

void WWDG_DeInit ( void   )

Deinitializes the WWDG peripheral registers to their default reset values.

Parameters:
None
Return values:
None

Definition at line 133 of file stm32f30x_wwdg.c.

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 191 of file stm32f30x_wwdg.c.

void WWDG_SetCounter ( uint8_t  Counter )

Sets the WWDG counter value.

Parameters:
Counter,:specifies 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 203 of file stm32f30x_wwdg.c.

void WWDG_SetPrescaler ( uint32_t  WWDG_Prescaler )

Sets the WWDG Prescaler.

Parameters:
WWDG_Prescaler,:specifies 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 149 of file stm32f30x_wwdg.c.

void WWDG_SetWindowValue ( uint8_t  WindowValue )

Sets the WWDG window value.

Parameters:
WindowValue,:specifies the window value to be compared to the downcounter. This parameter value must be lower than 0x80.
Return values:
None

Definition at line 168 of file stm32f30x_wwdg.c.
