  • OBD-II Mac interface?

    Hi, i'm aiming to upgrade my car with my 2006 Tax return, and i'm starting to weigh my options. I'm trying to decide between a Pioneer Avic N2 and setting up a Mac Carputer. I know that the Avic does not have a OBD-II interface, and i've read that a mac can use a couple of the PC versions while emulating.

    Is there any OBD-II interface or software that works natively with a Mac?

    Would a simple gadget like this

    work better just to beable to see the data?

    i have freediag working on osx

    freediag can be found here: freediag.sf.net
    i'm not sure if the current CVS source will work on osx. but i have a version that another guy and i got working. if you would like the source let me know.

    to connect the computer to OBDII i used the BR-3 which you can find here:
    http://obddiagnostics.com
    this was then connected using a keyspan serial to usb connector.

    cool stuff!

      I am not a programer, but looking at the widget programming guide, could you not make a widget that called the freediag command line and returned a value so you could have a GUI?

        unfortunatly no you could not. freediag has it own cli. it displays all the data in a kind of table like format within the shell. i did start to work on a cocoa interface but didnt get to far because of other projects. the freediag program is written in c so an gui interface can be written for it.

          Can you post your version that runs in osx? I can't find it online anywhere

            sure here is the source code. it is in xcode 2.1 but should compile without it.

              i started doing some testing with that code and it does not work on tiger. i haven't used it since panther.
              there is a problem with the serial connection code in diag_l0_br.c
              i will try and work on it and post the changes when i get it working.

                Thanks

                  Check the OBDII forum. You are looking for obd2gpslogger by Chunkyks. There's a forum for it. Runs in OSX.

                    Also it's in my sig :-D

                    Actually, this reminds me that I need to do an OSX build. If you give it a couple hours, I'll put up an OSX app bundle for download; I tagged a new version of the software yesterday.

                    [Or, if you're a developer and can build and install stuff yourself, feel free to grab the source and go to town].

                      EDIT: Ignore everything in this post. Nothing to see here, move along. Read my post below this one.




                      Well, that was ... "fortuitous" ?

                      I haven't loaded obdgpslogger on my mac recently, and 0.10 appears to be busted on OSX - glad I did that build, else I wouldn't have noticed. I've put up a build of 0.9 for OSX here: http://icculus.org/obdgpslogger/down...0.9-Darwin.dmg

                      It works for me, but be warned that the big feature added in 0.10 was baudrate voodoo - if you're using an OBDLink with the default settings, you'll run into some problems. Look forward to a fix soon [hopefully!]

                        And one more message for luck: never mind me, I'm an idiot. I had the baudrate set to 38400 in the config file in my home dir, and was testing with my OBDPro [which is 9600]. So, in other words, 0.10 works fine, but I'm an idiot..

                              well unfortunately I wont be able to test it quite some time as I don't have an OBD-II cable yet... or a an adapter for the cable but it's nice to know that it should all work and i now have all the right stuff to get it to do so (software wise). Thanks for your help.
