Hi @coryjfowler @SketchThis I am using CAN-BUS Shield on top of Arduino Uno. I am facing the similar errors like above.

Even I tried using the library which you mentioned "https://github.com/coryjfowler/MCP_CAN_lib by @coryjfowler"
but no luck. please help! Thanks.

I suspect the chip select pin on the shield is not at the default position for the library, this can be changed in the sketch to accommodate the shield. I cannot access robotdyn[dot]com at the moment, so I can't see what the shield looks like and suggest the correct pin for the chip select.

Hi @coryjfowler , Thanks for your comment.
I guess, 'robotdyn' stopped its production but some information you can see on here. http://useshop.co.kr/shop/item/5355132/
This shows the CS pin 10 as shown on the backside of the board in this link.
I tested it with CS_Pin(10) but it gives me same result. Could you please share a basic test code to check this, if any?
Thanks.

The loopback example is the basic test. At this point assuming we are still using an Uno or similar where the SPI pins appear at both 11-13 and ISCP header, then I would suspect that the shield has a clone or fraudulent part that does not function as we and the library expect it.
