Has anyone tried using the MCP2515 and writing code for reading and sending CAN-BUS messages yet?
I would not be surprised if some of the aftermarket tuners / programmers used something similar for their features. There doesn't seem to be much in the way of public information available about the various CAN-BUS messages for different vehicles though.
I'm thinking it might be interesting to experiment with it using an Arduino microcontroller.
My understanding of the CAN-BUS so far is that it changes the way we go about controlling devices on our vehicles. Instead of having a switch that directly makes a connection to control a light, you might have one of these a pod of switches that have a microcontroller connected to them which upon sensing a change in the state of the switches, sends an appropriate CAN-BUS message on the vehicle's CAN-BUS network. This message might be read by another microcontroller somewhere else that determines what to do with that type of message. I suspect that this means a lot of small gauge signal wires running around the vehicle instead of larger gauge power wires.
