Building a CAN API for Arduino DUE

Hi guys,

After being successful in the test between CAN bus 0 and 1 in Arduino Due, I've tried to receive messages from an ECU. This ECU sends 13 CAN frames of 64 bytes each one. I'm able to read the first frame but I have no idea about how to read the rest of them. By reading, I guess that the ECU is working with extended frame so I've been trying to mask the whole ID (CAN_ID and frame_ID), setting uc_id_ver=1 and some other options but nothing worked... Am I right with the extended frame CAN bus version? Has anybody experience on that? Is this library working with this kind of CAN bus?

Thanks!!
