Sounds good beyerch. Im all for getting the J2534 cleaned up and running smoothly.

If its performance can be made to be on par with the vx nano, or better than I would be absolutely wrapped.

No problem, I know ALDL inside and out.. its fairly simple the way it works, I have examples on the software implementation for ALDL using J2534 which was abit of trial and error before finding the method that is supposed to be used.
Firmware wise, its basically just using a serial port (Or software serial/bit banging). The hardware would need to sync up with the car by searching for a small time gap (few milliseconds) and then continue processing each frame as it comes in.

There is then only a couple GMUART specific commands to implement. SetPollResponse and BecomeMaster.
As far as the tech document indicated, these two commands are for:
SetPollResponse: The custom message sent when BecomeMaster is commanded. This is generally used to do something like disable car communication (F1,56,08,B1).
BecomeMaster: Used to request ownership (Master) of bus. Realistically... all this means is it sends the message indicated in the Pollresponse.

After that.. its pretty standard read/write msgs.

Was going through the firmware on this the other day.

Amazing work done so far! The windows api side is a bit messy, I can see what beyerch meant about that.
Bit of work there and looks like it would be a go!

Really need to separate the J2534 DLL API used with the hardware, and the J2534 sample used to communicate with the DLL API as its a bit confusing to what goes to what there.

Other than that, Im pretty happy to try order a board and give this a whirl!!

Is there any chance of finding pre-built devices for sale anywhere?
Please don't PM me with technical questions - start a thread instead, and send me a link to it. That way I can answer in public, and help other people who have the same question. Thanks!

looking for ALDL software on Github, I found another hardware project:

Hmm, Interesting project, first time I've seen it ...

What's up with it ??

Why hasn't this gone forth ??

Isn't it worthy ??

Has anyone ordered a board (or bread boarded it) and got it to work ??

In case anyone is interested: https://oshpark.com/shared_projects/21VTyHgL, I suspect there are better options.

BTW beyerch, love the line,

Having a hard time wrapping my oxygen deprived and inexperienced mind around the hardware.

Could you more experienced folks tell me if this device (hardware wise) would be compatible with most vehicles ??
Not concerned about firmware or drivers, just the hardware.

If not, what vehicles would it not work on ??

Thank you!

just from the protocols in the specs, yes it would be compatible with most cars
