I am trying to connect a CAN-BUS Shield to my RedBoard Plus to get information from the car via OBD II.
At first, I tried to see if the SparkFun CAN-Bus Arduino Library would work with just the RedBoard Plus and CAN-BUS Shield connected, but first, it does not initialize correctly. The serial monitor shows "Can't init CAN".
I did some light debugging and found that the CANSPEED_500 passed in CanbusClass::init() is not set in the register and mcp2515_read_register() returns zero.
Is the board broken? Can someone please advise?
