Hi, I’ll be happy to collaborate.
This is how far I got:
- I bought two of these boards:
SAE J1939 ECU Simulator Board For PC, Raspberry Pi, BeagleBone, Arduino, Teensy, Linux, Windows
Or you can buy two here.
I thought one board would be enough in my case, but my understanding is that we need two nodes to establish a CAN network, hence the need for two. I could not make it work with only one board and the tracker one. I suspect I would need to run the ARD1939 stack (more on it below) on the tracker for that to work, but in my case, the tracker one will only be listening, hence I do not think I need to invest time in it.
- these two boards give me a CAN bus now operational. Searching the internet I was able to find this paper and change some settings with masks and filters on the MCP25625 CAN controller that the tracker one has (basically disabling them, I think). They have screenshots of how they did it on Arduino. I’ll be doing the same on the tracker.
There is some integration Particle has done with what this person, Wilfried Voss at Copperhill Tech, has done: ARD1939, and you can find it here. I did not use this yet.
Let me know if that helps.
Thanks
