Hi，

I know the LPC1549 support for CAN2.0b part already and I use CAN2.0a protocol very well now.

how to configure the LPC15xx can2.0b protocol on CAN OPEN ROM API?

accrod to SAEJ1939 protocol, example: PGN = 0X1234; ID=0X12341234;

but i don't know how to configure these parameters?

id = CAN_MSGOBJ_EXT | CAN_MSGOBJ_DATA | ID？

mask = PGN？

Thank you
