I was playing with the idea of designing my own cable for CAN Bus communication,
Before I have started I have searched for available solutions, to save my effort.

And it turns out there are couple of available solutions - not counting ELM327 itself.

Now there are two options I found usefull,
first one mimics ELM327 in the sense of the protocol


and the second one seems to be fully compatible with the way tephra logger and evoscan works


I hope it saves someone a lot of search.

 

Very good stuff, thanks for sharing those! (Do you ever actually sleep, or have you found some way to keep doing this stuff 24 hours a day? )

The first one is interesting; since it's an ELM-compatible device, my knee-jerk reaction is "ugh, no protocol changes for you". But, since the firmware is available, it ought to be possible to extend it as needed. PIC programming makes my eyes bleed, though.

The second one, though, is really cool. It looks a lot closer to what Colby did with OP2.0, no? (Has anyone ever pulled one of his devices apart to see what micro he used?) The fact that you could pick up an off-the-shelf CANDIP/M162 (and one of the activity boards for development) to run his code on is a big leg up for someone just wanting to try out a small project or two.

 

That is only an illusion created by different timezone CST vs. CET

I understand that you are lazy coding PIC but there are ready to use libraries too.

There is even development board from ATMEL, but then the cost would reach the cable price
