I got an vehicle that was used as an experimental platform, with a lot of sensors and motors all connected to servo controllers that talk to each other by CAN.
I do not have any documentation about the machine concerning CAN and I am new to CAN bus.
I could connect a CAN card and see that there are some messages on the bus when I turn on the servo controllers.
1. How can I know the relation between the CAN ID and the sensor sending the message? Was the identifier something that was programmed in some eprom or set in some jumpers?
2. Also, if I want to send 5V to motor A , how can I set and identifier that say "this frame contains voltage for motor A"? And how can the motor A understand the message is for him?
Thank you. Any help is appreciated.
