Can you help me send information to the vehicle’s canbus line via ADU?
Hi,
We need more context.
What do you want to send and why?
The car’s body is in sleep mode, and many things in the original dashboard work via CAN-BUS. To operate the dashboard, I need to read data like speed, temperature, and mileage from the CAN-BUS to the vehicle.
The ECU I use is Ecumaster Classic, connected to the ADU via serial communication.
I need to send can-bus data from ADU to the vehicle body. Can you help .
Do you know the CAN IDs to which you want to send this data? Do you have a DBC file for that car?
I don’t know for sure but it’s the same as the 206 rc can configurations in ecumaster black
My only goal is to send a signal from ADU to the Can-Bu line like Ecumaster Black does. There is already a protocol in Ecumaster.
Could you share your project? I will set the CAN bus exports to behave as in the Black for the 206 RC.

this is my file
Here is your modified project. I have set it up to send frames on CAN2, so it might require changes according to your setup. There is not much information, only the RPM, CLT, and Check Engine light. We do not send more information in the Black.

I will test it and get back to you
It will probably be enough
water temperature and tachometer worked
Can I read the right signal, left signal, high beam, low beam, fuel gauge, etc. via the canbus and run them on the same?

Do you want to read those signals and show them on the ADU? Why not? If you know how to find those signals, you can do what you want with them.
I’m researching Canbus data, but I don’t know how to adapt it once I find it. I’ve set up everything visually, but I don’t know the coding.
So give an example of what you have found and what you want to do.
Data such as right and left turn signals, high and low beams, and fuel gauge are sufficient for me.
I found this data and I think it will be useful.
Here is an example for the left/right indicators. Based on this example, you can do the rest on your own.
First, create the CAN bus Message Object:
Next, create the CAN bus Input for the left indicator:
Based on what you shared: Frame ID: 0x128,
Byte offset: the byte on which the light indicator signals are located: 4 (counted from 0)
Bit count: 1 - the information whether the indicator is on/off is on a single bit.
Bit position: 1 (counted from 0)
The same for the right indicator:
The right indicator signal is on bit 2 in byte 4.
Based on that knowledge, you should be able to recreate the rest of the signals.
