Can Bus Lighting Control System

Hello,

“Message Sent Successfully” showed you can initiate your shield successfully, there is no problem with your hardware.

But “Error Initializing MCP2515”. was also shown in some examples, so I guess that you forgot to check this line of code, the value is 9 or 10, which depends on shield version.
</s>MCP_CAN CAN0(10); // Set CS to pin 10<e>
Sounds that you just need to analyze the signals without programming, why not buy a USB-CAN-Analyzer? That would save a lot of time.
