J2534-2 support status

[athach]

First of all, thank you very much for sharing this repository. It looks very useful and I plan on using it in a boot loader application.

I can see that you have implemented some features from J2534-2. It has been revised with more functionality three times in 14 years. I think it would be good if you list which features are implemented on the first page of the repo.

Thanks

My goal is to have it implement everything. As it sits, it should be possible to manually specify protocol and bauds so you should theoretically should be able to implement anything. It is helpful and expressive to have enum definitions for these things, so I will add those as I learn about them. I haven't worked in the automotive space in a while, so, I might be behind on the latest in 2534. If you let me know what/when things need to be added, I will do my best to keep it up to date.

Actually I dont really need anything at the moment. It was just an idea that crossed my mind. Since there are several updates of the specification it is not clear which parts are implemented. I gathered this from the SAE website. I was interested in CAN FD and as far as I can tell that is not implemented.

2020 update
This update to API version 04.04 of the SAE J2534-2 specification is to add support for Ethernet NDIS protocol and the read voltage on an SAE J1962 pin functionality.

2019 update
This update to the SAE J2534-2 specification is to add support for CAN FD protocol, and ISO 15765 on CAN FD protocol.

2010 update
Added ability to access multiple devices simultaneously
Added support for UART Echo Byte Protocol
Added support for Honda Diag-H Protocol
Added support for Repeat Messaging
Added support for Extended Programming Voltage
Added support for SAE J1939 Protocol
Added support for SAE J1708 Protocol
Added support for Device Parameter configuration
Added support for TP2.0 Protocol
Added support for Fault-Tolerant CAN
Added Discovery Mechanism to discover the supported features
Other editorial changes

It looks like I currently have first class support for everything you have listed except for the 2020 update. You can find the enumerations in Protocol.cs.

If you have the 2020 addendum, you can email it to me and I will add definitions for it.

For CAN FD rx and tx flags are missing, See tables 92 and 93 in the document, Maybe the data phase baud rates should be in baud.cs (table 90)?

I am also interested in CAN FD support.

If there is any way I can help let me know.

So, I have looked at this and it appears there have been some extensions added for TP2.0 that have overlapping flags and statuses. I'm not sure what the best way to deal with this might be. I'm thinking that a separate enum with the TP2.0 stuff would probably be the best way.
