Read OBDII Source Code?

**Zharvek** · 01-16-2005, 01:23 PM

I've searched around the forums and found some people were able to make a program to extract data from the ECU using OBDII. I was wondering if anyone could post some example source code (Prefer VB6) to open the COM port and read the data.

Im not looking for a neat virtual gauge cluster at the moment, just the foundation for connecting and displaying data in a few text boxes.

Thanks.

Sorry to do this bud, but

brought up a whole buncha stuff.

But here's the MS has to say about it:
MS: VB6 Serial Communication

Is that what you were looking for?

Once you establish a connection, you need to parse the data, and feed it into your math or other textboxes and stuff.

I wrote a plugin you can call from VB that will do most of the common OBD II stuff you would want to do. OBDII / Elm MPG meter. Almost working but not quite!

Okay thanks god_of_cpu I will look into your plugin!

I currently have the BR3 interface and was hoping somebody would have done it already, but Frodo is making an SDK and some applications for it. Im just waiting on him. Go Frodo!

I'm hoping to get some work done on the data provider soon.
I may release some examples for frodocomm so people can
see the progress.
