Re: [avr-chat] CAN controller

[Dean Ferreyra]

Hi Matt,

I do have some old code I used with an MCP2510 and the ATmega103 that 
I can email you if you are still having problems.  I used it 
successfully in a manufacturing automation product.

I have to say, though, that the code is probably 3 or 4 years old at 
this point, and it's not going to be immediately useful since it has a 
number of dependencies on other code that I can't send you.  At best I 
would say you can study it to see if you're missing any initialization 
steps, etc.
