Hi,
I've been doing research on how to activate CAN on my ECU and I am overwhelmed with confusion. Any help I can get will be greatly appreciated.
I am delivering an engine with an onboard ECU (from Woodward) which is CAN-ready. There is an isolated port with 4 pins (CAN_H, CAN_L, Com, and Shld). I need to make various engine parameters (i.e. coolant temp. and oil pressure) available through CAN becauase the engine is being thrown into a system with various other components and a controller.
My main confusion is where the sensors are wired. These are standard analog/boolean automotive sensors. Do the sensors represent "Nodes" in a CAN system, or do the analog signals go to the ECU analog inputs and then passed through the ECU to the CAN port via software?
I have 2 ECU's...to test the CAN ports can I connect the 2 ECU's and have one writing and one reading? I'd like to do this in place of buying one of the controllers from Kleinknecht.
Are there any other good resources to help me get started?
Thanks in advance.
