Thread: New, Free, OBD and GPS Tool

0.3 isn't out yet. At least for now, I recommend sticking with the subversion flavor.

Nice work, man!

I have nothing to read OBD data yet, but now that I know there is a linux-native tool, I'll be looking around.

Yeah, I am another linux junkie and categorically refuse to put windoze on any of my computers, for any reason. (Bad enough I have to use it at work.)

I can barely type, much less write code, so thanks for the effort and the thread to let us know its around.

COM and DCOM is stil present in Windows 7, so I figure they still keep it alive for a little while longer

I allways note the odometer before and after a check-up of the car. But, sometimes the temptations is to great for the mechanics and they really take off with the car.

There is an example here in norway, where the owner of a highly tuned M3 car delivered it for service on a BAVARIA (BMW) dealer. He clearly specefied that there where NO need to take the car out for a spin to check if everything where OK for the service they where going to to on the car, something BAVARIA confirmed... Non the less, when he came back to pick up the car.. The first thing he did, where to check the tracker log that he have installed in his car.

This is a list of things he could read from the log.
* Car traveled over 100Km since he delivered it, untill he picked it up.
* On a cold engine/turbo they kept over 6.000 RPMS over a long period of time.
* Can't remember the temperature on the breaks, but they where glowing hot.
* The GPS "spy" told that the mechanics had been doing about 200Km/t in a 60 km/t sone.
* There where more, but I can't remember them.

The end of a long story that ended in court.. He got the service for free as compensation...

After this, he configure the engine management with a "owner not in car" feature... max 2.000rpm and speed limit on 80Km/t.

But back on topic....
Love the work you have done, and will follow it, even when I'm doing a windows install in my car.

I have been playing around in POSIX and find this very interesting!

So, I just hunted down a windows machine, and tried building with cygwin. Evidently it works just fine.

If you're on windows and want to try my software, it's easy to do. Visit the cygwin website above, download the setup package. Run it. [you'll only have to do this part once, ever]

All the default options will be fine, but when you get to package selection make sure you add:
devel/cmake
devel/gcc [which will also select a bunch of other gcc-{something} packages that you need]
devel/make
devel/subversion

open cygwin [the shortcut installed in your start menu or desktop, it will start a terminal window that gives you a prompt], and run these commands exactly as-is:

Code:

svn co svn://svn.icculus.org/obdgpslogger/trunk obdgpslogger
mkdir obdgpslogger/build
cd obdgpslogger/build
cmake ..
make

Assuming it builds without issue [and if it doesn't please let me know], then you can run the tools thus:

Code:

../bin/obdgpslogger -s {serialport}
{wait some time while you log stuff, then hit ctrl+c at the end}
../bin/obd2kml

Have fun all. Reading back, that's actually a lot more technical than I was anticipating, so I fully empathise with anyone unwilling to bother. But if you do, please post here with success or failure.

New version is out

Now has support for trips [multiple car trips in same logfile/database]
A tool to export useful stuff to CSV
... and some nerdy technical changes no-one cares about :-)

Some new screenshots from google earth:



Have fun everyone,

Perfect timing! I just bought an OBDpros scanner. That and I only run windows in parallels if forced to by inconsiderate gadget makers. I think a gps unit will be next on my toys list now. I'd been putting off getting a scanner due to the lack of good osx software, this is really great news.

Can't wait to try it out.

Do you think this would also work as a track-day data-logger ? Apart from the hassle of securing a laptop ...
