CAN Bus Shield Problem

Using Arduino Networking, Protocols, and Devices
1

Hello,

i am struggling with the CAN Bus communication and would Appreciate your help.

I have got Sparkfun CAN Bus shield and Arduino Uno. Using these I prepared two setups one for sending and one for recieving. But I am not able to have any communication. I am using the code from this page

http://henrysbench.capnfatz.com/henrys-bench/arduino-projects-tips-and-more/arduino-can-bus-module-1st-network-tutorial/

I have already added 120 ohm resistors on the connecting wires.

Please help me.

Have you tried the examples from SparkFun?

Yes

I did but in that case as well no messages are being exchanged.

I have attached the Image and apart from CAN Init nothing seems to work. Any Suggestions?

Not from me.

Rarely have I found (actually I have never found) either AdaFruits or SparkFun's examples to have a problem when connected exactly as shown and uploaded without modification.

Thank you for the insight.
