 ===============================================================================
                ##### CAN Frames Transmission functions #####
 ===============================================================================  
    [..] This section provides functions allowing to 
      (+) Initiate and transmit a CAN frame message (if there is an empty mailbox).
      (+) Check the transmission status of a CAN Frame
      (+) Cancel a transmit request

Function Documentation

void CAN_CancelTransmit	(	CAN_TypeDef *	CANx,
		uint8_t	Mailbox
	)

Cancels a transmit request.

Parameters

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

Return values

None

Definition at line 703 of file stm32f4xx_can.c.

uint8_t CAN_Transmit	(	CAN_TypeDef *	CANx,
		CanTxMsg *	TxMessage
	)

Initiates and transmits a CAN frame message.

Parameters

CANx	where x can be 1 or 2 to to select the CAN peripheral.
TxMessage	pointer to a structure which contains CAN Id, CAN DLC and CAN data.

Return values

The	number of the mailbox that is used for transmission or CAN_TxStatus_NoMailBox if there is no empty mailbox.

Definition at line 577 of file stm32f4xx_can.c.

uint8_t CAN_TransmitStatus	(	CAN_TypeDef *	CANx,
		uint8_t	TransmitMailbox
	)

Checks the transmission status of a CAN Frame.

Parameters

CANx	where x can be 1 or 2 to select the CAN peripheral.
TransmitMailbox	the number of the mailbox that is used for transmission.

Return values

CAN_TxStatus_Ok

if the CAN driver transmits the message, CAN_TxStatus_Failed in an other case.
