    [..] This section provides functions allowing to 
      (+) Initialize the CAN peripherals : Prescaler, operating mode, the maximum 
          number of time quanta to perform resynchronization, the number of time 
          quanta in Bit Segment 1 and 2 and many other modes. 
          Refer to  @ref CAN_InitTypeDef  for more details.

Function Documentation

void CAN_DBGFreeze	(	CAN_TypeDef *	CANx,
		FunctionalState	NewState
	)

Enables or disables the DBG Freeze for CAN.

Parameters

CANx	where x can be 1 or 2 to to select the CAN peripheral.
NewState	new state of the CAN peripheral. This parameter can be: ENABLE (CAN reception/transmission is frozen during debug. Reception FIFOs can still be accessed/controlled normally) or DISABLE (CAN is working during debug).

Return values

None

Definition at line 493 of file stm32f4xx_can.c.

void CAN_DeInit ( CAN_TypeDef * CANx )

Deinitializes the CAN peripheral registers to their default reset values.

Parameters

CANx	where x can be 1 or 2 to select the CAN peripheral.

Return values

None.

Parameters

CANx	where x can be 1 to select the CAN1 peripheral.

Return values

None.

Definition at line 167 of file stm32f4xx_can.c.

void CAN_FilterInit ( CAN_FilterInitTypeDef * CAN_FilterInitStruct )

Configures the CAN reception filter according to the specified parameters in the CAN_FilterInitStruct.

Parameters

CAN_FilterInitStruct pointer to a CAN_FilterInitTypeDef structure that contains the configuration information.

Return values

None

Definition at line 334 of file stm32f4xx_can.c.

uint8_t CAN_Init	(	CAN_TypeDef *	CANx,
		CAN_InitTypeDef *	CAN_InitStruct
	)

Initializes the CAN peripheral according to the specified parameters in the CAN_InitStruct.

Parameters

CANx	where x can be 1 or 2 to select the CAN peripheral.
CAN_InitStruct	pointer to a CAN_InitTypeDef structure that contains the configuration information for the CAN peripheral.

Return values

Constant indicates initialization succeed which will be CAN_InitStatus_Failed or CAN_InitStatus_Success.

Parameters

CANx	where x can be 1 to select the CAN1 peripheral.
CAN_InitStruct	pointer to a CAN_InitTypeDef structure that contains the configuration information for the CAN peripheral.

Return values

Constant indicates initialization succeed which will be CAN_InitStatus_Failed or CAN_InitStatus_Success.

Definition at line 197 of file stm32f4xx_can.c.

void CAN_SlaveStartBank ( uint8_t CAN_BankNumber )

Select the start bank filter for slave CAN.

Parameters

CAN_BankNumber Select the start slave bank filter from 1..27.

Return values

None

Definition at line 468 of file stm32f4xx_can.c.

void CAN_StructInit ( CAN_InitTypeDef * CAN_InitStruct )

Fills each CAN_InitStruct member with its default value.

Parameters

CAN_InitStruct pointer to a CAN_InitTypeDef structure which ill be initialized.

Return values

None

Definition at line 425 of file stm32f4xx_can.c.

void CAN_TTComModeCmd	(	CAN_TypeDef *	CANx,
		FunctionalState	NewState
	)

Enables or disables the CAN Time TriggerOperation communication mode.

Note: DLC must be programmed as 8 in order Time Stamp (2 bytes) to be sent over the CAN bus.

Parameters

CANx	where x can be 1 or 2 to to select the CAN peripheral.
NewState	Mode new state. This parameter can be: ENABLE or DISABLE. When enabled, Time stamp (TIME[15:0]) value is sent in the last two data bytes of the 8-byte message: TIME[7:0] in data byte 6 and TIME[15:8] in data byte 7.

Return values

None

Definition at line 523 of file stm32f4xx_can.c.
