v2 - can't decode IC_204 VCD_06_Menueaktivierung coding string

[Mattwmaster58]

Vediamo can access and code this VCD:

While Diogenes can load the fragment names, it can't load the coding string or the available fields for each parameter.

Is there a way to debug this without having to be connected to the car? I am interested in fixing this but not if I have to be tethered to the car.

I don't think there's a quick and easy way to do that; if I remember correctly, I hacked up some j2534 library to sufficiently respond like a target ECU when I had to test stuff out, just the basics like session requests, testerpresent, identification.

If you go for this route, you'll probably want to pick your preferred language to build the emulation DLL. From my experience, .net (via DllExport : https://github.com/3F/DllExport) is alright to work with and I think works okay with Diogenes, but Vediamo does not like that and will crash. Vediamo prefers a regular MSVC DLL. Rust looks promising too but I'm not experienced enough to comment more about that.
