Corsa D, MS-CAN

Hello CAn Hacker.

I'm looking for someone who can create a data log for me on the MS-CAN bus (92.2 kbit/s), specifically using pin 3 [H] and pin 11 [L] of the OBD2 connector.
In the car, it should have the GID (large monochrome pixel display) and not have the Touch & Connect feature. (Unfortunately, I have the T&C installed in mine, which is why I need your help).

Three scans need to be recorded.
1. When the Setting button is pressed and released.
2. If the radio is on and the RDS station name is displayed on the screen, take a picture of the display using the GID so I can identify it.
3. if the input is set to AUX.

Thank you very much.
Frank.

Hello Frank,

Please provide contact information (e.g., a disposable email address, mobile phone number, etc.) so that customers other than your own can reach you.

Good luck, Rainer.

Thank you. Contact: digidax@gmx.net

92.2? Should be 95.238.

The settings button should be in the same location as it is on the Vectra C.
01 FF = Press.
00 FF 01 = Release.
(On ID 0x206)

I can't provide any further assistance because I no longer have the original radio installed, and I have the CID unit. However, the GID unit is likely compatible and can be connected in a similar way. Especially since, as I said, I have a Vectra C .

Okay, 95,238 is correct, but I need to use a different interface. The RKS-CAN module doesn't receive anything with the setting of 95238.

At address 0x206, I have the value 00 91 01 in the normal state. I will try setting it to 01 FF and see what happens.

Thank you very much.
Frank.

Hmm, maybe it's different in the Corsa.

Code:

if (serialCommand == "BTN_OK") {         sendIntoCAN(0x206, 3, 0x1, 0x84);         sendIntoCAN(0x206, 3, 0x0, 0x84, 0x1);       }       if (serialCommand == "BTN_SETTINGS") {         sendIntoCAN(0x206, 3, 0x1, 0xFF);         sendIntoCAN(0x206, 3, 0x0, 0xFF, 0x1);       }       if (serialCommand == "BTN_BC") {         sendIntoCAN(0x206, 3, 0x1, 0x1);         sendIntoCAN(0x206, 3, 0x0, 0x1, 0x1);       }       if (serialCommand == "BTN_MAIN") {         sendIntoCAN(0x206, 3, 0x1, 0xE0);         sendIntoCAN(0x206, 3, 0x0, 0xE0, 0x1);       }       if (serialCommand == "BTN_UP") {         sendIntoCAN(0x206, 3, 0x8, 0x83, 0xFF);       }       if (serialCommand == "BTN_DOWN") {         sendIntoCAN(0x206, 3, 0x8, 0x83, 0x1);       }

There are still the other buttons that I have in my source code .

Okay, I'll take a look at that this afternoon.

Actually, I want to transfer and display the values from a wheelchair battery to the GID, which is being charged in the trunk during the drive. To do this, I changed the GID setting in OP-COM from "without radio - Touch & Connect," which is what's installed on the CD60, to a blank setting. Now I have two empty tabs and the trip computer, but the "Settings" tab is missing. It would then be virtually present on the radio, so when I send the correct message, the settings window for the virtual radio should appear.

Then I would have to try to populate the empty fields via the CAN bus. I found some frames online for the Astra, but unfortunately, I can't log any myself because the Touch & Connect system doesn't transmit any frames to the GID (Graphics Information Display).

Thank you for any help.
Frank.

There is also a "Settings" tab, even without radio

Code:

sendIntoCAN(0x691, 8, 0x41, 0x0, 0x60, 0xC, 0x82, 0x0, 0x2, 0x2a); sendIntoCAN(0x766, 8, 0x41, 0x6, 0x46, 0x4, 0x1, 0x2, 0x0, 0x0);

.

The other two tabs are blank because you first have to pretend that a radio is turned on.

Here's how I do it for the radio and navigation system:


Every few seconds (I send it every 2 seconds). Then the symbols should also appear in the tab (assuming that the Corsa and Vectra infotainment systems are identical).

You should listen to 0x6C1 for some text.

You might need to set the drive to CD70/DVD90 mode, as I had a CD70 installed.

I have a tablet installed in my car, and I wanted it to be integrated as seamlessly as possible, including the head unit, OEM display control, and the original hands-free system.

Or, I once had a friend display a specific value from his engine control unit in the FSE section (in his Astra H) because he wanted to keep an eye on it . By the way, the controls were absolutely identical compared to my Vectra.

Absolutely brilliant.
You're really helping me out.

Here's what I recorded on the MS-CAN yesterday:

I have researched that 6C1 is used for RDS and 6C7 for telephone, and accordingly, the structure of the multi-message, which then increments from 21 to 2F.

There's a CU Unit available for the Astra, and the Czech user says that it fills the entire display, and you can even add new entries on the left side.

What settings do you have for the MS CAN in the KCAN Monitor? Unfortunately, nothing happens with 95238.

I don't have a KCAN, I use an Arduino with an MCP2515.

When I'm at home, I'll check if I still have my handwritten notes. I had roughly written down which byte corresponds to what on the 6c1 device. It was a huge amount of work for me, because it was my very first CAN project, and I had never worked with CAN before, let alone with microcontroller programming .

I've also experimented with building my own menus, just to see how it works. It's possible. I didn't elaborate on that further.

Have you ever tried adjusting the bitrate, both higher and lower?
Please do not include periods or commas when specifying the bitrate; I'm concerned that if you do, the system might only consider the number "95".

Best regards, Rainer.

I'll try that later.

Thank you. Best regards, Frank.

I tried using 95238 and 95200, but without success. On the HS Can device, the interface works with 500 k. Alternatively, the Peak CAN interface can operate on the same connector at 95.238 kbit/s, which eliminates the possibility of a reversed H/L configuration.

What else can I test?

Hello,

I'll take a look at the code later to see how the chip registers are set based on the input bitrate.

Trying bitrates of 95500 and 95000 would be worth a shot. The adjustable bitrates aren't arbitrary; they must be generatable as integer multiples of the base clock on the CAN bus.

Best regards, Rainer.

Update: Using a virtual serial port and the ASCII interface, the bitrate can also be adjusted, similar to how it is done with the SJA1000.

Command Snnmm -> Sc34e to open the CAN bus at 95238 bits per second.


You might want to test this with the appropriate values. I couldn't find any errors with the "syXXXXXX" command, at least.

If someone could send me a control unit that produces the incorrect bitrate, I could debug where the problem lies. http://www.kaufmann-automotive.ch/en/RKS+CAN-ASCII-Interface.pdf

Best regards, Rainer.
