Hi Bas,
the picture uses the can bus shield v1.2. we upgrade it to can bus shield v2.0 now. But you can check the v2.0 and v1.2 differences on http://wiki.seeedstudio.com/CAN-BUS_Shield_V2.0/. they use same chips and did some small modification. can bus shield v1.2 shall support the function. i went through the documentation that it needs the hardware to simulate the issue. So i can not test it and verify it. thanks for understanding.
