Logger OpenPort 2.0 Integration

kascade · **Posted:** Thu Sep 18, 2008 5:37 pm

It's probably worthwhile having a thread with updates regarding integration of the new OpenPort 2.0 cable into the RomRaider logger.

I received my cable last week and since its arrival have been working away on getting some Java code together that can talk to it (via its DLL) and then to the ecu, all using the J2534 API. Last night finally saw some success when I was able to successfully send an SSM ecu init and receive the ecu's response.

Next step will be to take the code I've put together, clean it up , make it reusable and start integrating it into the logger itself (currently just a small standalone test app). No ETA as of yet but a big step has been made and the rest should just be grunt work.

Big thanks to Colby who has provided help, advice and tips over the last week and for graciously donating a cable to the cause!

Great work Paul! Keep it up, many people are SOL with the new cable and no EcuFlash logger to date. Not to mention the lack of 1.3 or 1.2 cables available now.

good to hear. Thanks Paul!

Would you be willing to share what you have so far? I just unwrapped my OpenPort 2.0 and I'm itching to get it working with my CarPC project (http://www.codeplex.com/ssm). I'm working in C#, not Java, but what you have so far would be very helpful - mostly I just want to see the sequence of calls to set up the connection and do a send and receive.

Whatever I come up with will be GPLed like the rest of my stuff.

Thanks!

Once it's in the logger it will be free for all to see. It's not ready to release any code yet but I can help out with the sequence of calls. At work atm, so will have to wait until the weekend...

I am happy to see this. Looking forward to the final product. I have a number of JDM Scooby's in my family that need logging so this will be a huge help.

Great to hear, thanks Paul!!!

Over the last couple of days I have manged to steal a few precious moments to get the new cable working in the logger. It wasn't all that difficult to get working actually. The existing connection code is pretty well abstracted (although pretty ugly in places!) requiring only minor tweaking. The next step will be to autodetect the type of cable connected, sort out some minor remaining issues and make sure the user experience is as seamless as possible. Depending on time available for me to spend on it, a first cut test release may be available by the end of the week...

Excellent news. Looking forward to it.

Man you are a legend, looks like it's about the right time to buy the new 2.0 cable

Prolly a little early to know, but will RomRaider logger also allow the ability to use the 2.0 cables inbuilt storage for logging without a laptop - or will that be an ecuflash only feature?

ecuflash only

You might want to take a look at the project at http://sourceforge.net/projects/j1699-3. It's written in C and uses the J2534 API to test ECU compliance with OBD-II standards. Also, a high level overview of the J2534 API can be found at http://www.openecu.org/index.php?title=J2534. Good luck!

Sorry for the hijack - just wanted to encourage developers, even if they aren't working on RomRaider.

No problem. I have gained a lot from the information available here: http://www.drewtech.com/support/j2534/index.html

Basic order of calls for sending/receiving SSM is:

-- Prepare connection --
PassThruOpen
PassThruConnect
PassThruIoctl (SET_CONFIG where P1_MAX=2, P3_MIN=0, P4_MIN=0)
PassThruStartMsgFilter (Create a pass all filter where mask=00, pattern=00)

-- Communicate ---
PassThruWriteMsgs (write SSM)
PassThruReadMsgs (loop until response read)

-- Close connection --
PassThruStopMsgFilter
PassThruDisconnect
PassThruClose

First cut of OP2.0 logger integration is almost complete.

Depending on what cable is attached it will automatically select the correct connection method. For the older 1.2-1.3 cables this will remain a straight serial connection over the selected COM port. For the OP2.0 cable this will be via the openport DLL and J2534 API.

Just need to sort out some usability niceties before release.
