 ===============================================================================
                  ##### CAN Frames Reception functions #####
 ===============================================================================  
    [..] This section provides functions allowing to 
         (+) Receive a correct CAN frame.
         (+) Release a specified receive FIFO (2 FIFOs are available).
         (+) Return the number of the pending received CAN frames.

Function Documentation

void CAN_FIFORelease ( CAN_TypeDef *  CANx,
uint8_t  FIFONumber 
)

Releases the specified receive FIFO.

Parameters:
CANx,:where x can be 1 to select the CAN1 peripheral.
FIFONumber,:FIFO to release, CAN_FIFO0 or CAN_FIFO1.
Return values:
None

Definition at line 773 of file stm32f30x_can.c.

uint8_t CAN_MessagePending ( CAN_TypeDef *  CANx,
uint8_t  FIFONumber 
)

Returns the number of pending received messages.

Parameters:
CANx,:where x can be 1 to select the CAN1 peripheral.
FIFONumber,:Receive FIFO number, CAN_FIFO0 or CAN_FIFO1.
Return values:
NbMessage: which is the number of pending message.

Definition at line 796 of file stm32f30x_can.c.

void CAN_Receive ( CAN_TypeDef *  CANx,
uint8_t  FIFONumber,
CanRxMsg *  RxMessage 
)

Receives a correct CAN frame.

Parameters:
CANx,:where x can be 1 to select the CAN1 peripheral.
FIFONumber,:Receive FIFO number, CAN_FIFO0 or CAN_FIFO1.
RxMessage,:pointer to a structure receive frame which contains CAN Id, CAN DLC, CAN data and FMI number.
Return values:
None
