Does your adapter use the MCP2515 too?

I started out using a MCP2515 chip. It will do the job well enough but since I ended up using the the teensy3.6, it already has that ability built in, so the answer is no.

The NXP processor on the Teensy3.6 has 2 can buss chips already on board as part of the processor itself. There was no need for any external can bus controller.



BTW: The pics of that board you listed shows a 12.0 MHz crystal. That will not work on J1939. It needs to be a 16.000 MHz crystal for that MCP2515 to work on vehicles properly. I think there is some restriction on selling MCP2515 boards with 16.0 MHz crystals pre-installed or something in some countries, etc. - So it is not uncommon to have to replace the crystal to the proper one on the board after getting it.
