#define canIdIsRtr(encodedId)
 Check if CAN ID is a Remote Transmission Request.
#define canIdIsExt(encodedId)
 Check if CAN ID is in extended format.


CanError canInit (unsigned port, unsigned baudrate, unsigned long options)
 Initialise CAN port.
CanError canInitEx (unsigned port, unsigned prescaler, unsigned timeSeg1, unsigned timeSeg2, unsigned syncJumpWidth, unsigned long options)
 Initialise CAN port (extended).
CanError canSetFilter (unsigned port, const CanFilter *filter)
