Discussion and questions related to the course CAN Bus Communications Decoded
I was trying out some of the skills and was looking for the engine speed signal and found what I thought may be it, but I noticed another PID with bytes located in different positions changing exactly the same. Is it possible that the engine speed is transmitted on multiple PIDs?
yes, this is quite common. Sometimes for backwards compatibility (ie, some old module looks for address XXX), but the new stuff knows that YYY is the preferred update. You might want to observe how frequently the different CAN IDs are updated.
Will do, thanks, David!
