Detailed Description

CAN Frames Transmission functions.

 ===============================================================================
          ##### 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 to select the CAN1 peripheral.
Mailbox,:Mailbox number.
Return values
None
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
Thenumber of the mailbox that is used for transmission or CAN_TxStatus_NoMailBox if there is no empty mailbox.
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 to select the CAN1 peripheral.
TransmitMailbox,:the number of the mailbox that is used for transmission.
Return values
CAN_TxStatus_Okif the CAN driver transmits the message, CAN_TxStatus_Failed in an other case.
