5. Syntax:
i32 getCanMessage( struct CanMsg *buffer, u8 count )
Description: This function receives CAN packets from the CAN bus subsystem.
Parameters: This function stores received CAN packages sequentially at an array of type ‘CanMsg’.
The number of packages to receive is indicated by the parameter ‘count’.
Return Value: If this function receives the CAN packet successfully, it returns 0, any other returned
value stands for error.
Here is an example:
If the array ‘canAry[]’ of type ‘CanMsg’ has been declared and allocated. The code listed below will
receive 30 CAN packages from the CAN bus subsystem and stores the packages in the ‘canAry[]’.
unsigned int result = 0;
struct CanMsg canAry[30];
result = getCanMessage( canAry, 30 );
if( result != 0)
fprintf( stderr, “Fail to receive CAN packets!\n”);
6. Syntax:
i32 getCanMask(struct CanMask *mask)
Description: This function gets the current setting of the acceptance masks. Masks are used to
determine which bits in the ID field of the CAN packet are examined with the filters. There are two
acceptance masks (mask0 and mask1) and six acceptance filters (filter0 ~ filter5) in the CAN Bus
