So, I decided to do a thing...

Yes, it's extremely slow, and yes, barely anything works, but we have an UI.

But why..?
Ive been messing with BMWs hardware and software for a while now, and keep on finding more and more interesting stuff. The next logical step was to make it run on something its not supposed to, and that's how HMI8 in a VM was born.

Hi. I'm testing a self developed CAN OBDII application, but I'm running into a road block.

I've confirmed that my node is synchronized to the bus correctly. When connected, no bus faults are reported, a successful transmission is reported when I send a frame, and I receive frames when I don't filter by CAN ID.

I've also tested communication with another node that I have, and that appears to receive the data I send correctly.

I'm having a problem requesting the supported PIDs. I'm requesting this with the following CAN frame:

CAN ID: 0x7DF
byte 0: 0x02
byte 1: 0x01
byte 2: 0x00
byte 3: 0xCC
byte 4: 0xCC
byte 5: 0xCC
byte 6: 0xCC
byte 7: 0xCC

I'm not 100% sure what to use for padding, but I've also tried 0xAA and 0x00. I'm setting DLC = 0x8

For the receive side; I'm looking for a response from 0x7E8, but have also checked for responses from 0x7E9-0x7EF.

I'm testing with a 2016 honda civic. Any help would be appreciated, thank you!

Hi

What tools are there can program/reflash ECU?

Hi all, not sure if ill get the answer i need but these codes are coming up on my vz commodore 2005, can anyone tell me what they mean?

I let a friendly LLM loose on a prototype vehicle tracker I'm building (https://l0destar.com) with a CANable interface and a scope. Quite impressed by the results: https://l0destar.com/canbus.com

It seems like from this report it should be fairly reliable but I don't have a car with a CAN bus to test it with. Is there anything further that's normally done to validate CAN interfaces?
