RobotDyn Shield
Hi there! I'm trying to get this CAN bus shield working:
https://robotdyn.com/can-bus-shield-for-arduino.html
I tried the Arduino library from here, burned it onto an Uno and mounted the shield. In the Arduino serial monitor all I get is this:
I found a fork of this library:
https://github.com/coryjfowler/MCP_CAN_lib by @coryjfowler
I setup the library and ran the "loopback" example file and I got this:
So this seems like I'm heading in the right direction, however when I tried some of the other examples I wasn't able to get any live data from my car. I believe I had the car's baudrate set properly... Not totally sure where I need to start looking here... Any help would be greatly appreciated!
Hi @coryjfowler @SketchThis I am using CAN-BUS Shield on top of Arduino Uno. I am facing the similar errors like above.
Message Sent Successfully! Message Sent Successfully! Entering Configuration Mode Failure... Error Initializing MCP2515... MCP2515 Library Loopback Example... Message Sent Successfully! Message Sent Successfully!
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.
