Logging custom CAN-messages

Post by EcoCars »

Hi, first post on the forum! :)
I would like to log custom received CAN messages and have after a few days of testing and searching not been able to find anything relevant. I thought about editing the source code, but thought I should consult all the knowledge on the forum first.
I am part of a research group who is building a small hybrid car, we have an established CAN-network used between the ECUs controlling the electrical motor, the ethanol engine and a bunch of other stuff. My question is how should I get the custom messages to be logged by the RCP2?
I have tried to use the existing predefined OBD-II channels but this have been unsuccessful since I can't set the channel to an custom CAN id.
I have written a lua-script to make sure that the messages is beeing recieved properly and that works fine.

Thanks for your input!

Hi,

Our CAN integration is done through Lua, mapping CAN data to virtual channels. You don't need to modify firmware.

See the guide:

One great example is the BMW E46 integration:

Let us know how your project goes!
