    CygWin Simulator - Running Sim & Application together?

    Hi guys,

    I managed to get the OBDII Sim working on cygwin pretty easily thru following the instructions.

    My goal is to simulate the OBD using the supplied simulator, and make use of the simulator in the Windows environment - is this possible?

    When running the sim over COM1 I'm getting a "port is already open!" error (which kinda makes sense :P)

    Cheers,

    Paul

    It sounds like you're trying to open COM1 with the sim, and then open COM1 with your application? That won't work in windows.

    Did you install com0com? The way that obdsim works is by opening one end of a virtual serial port [defaults to CNCA0, IIRC], and then you point your OBDII application at the other end.

    com0com is here: http://com0com.sourceforge.net/.
    I wrote some instructions on using obdsim on windows here: obdsim-on-windows.txt
    Which is just a shortened version of the real com0com README

    Yeah... did the classic of posting the query and only then looking in the /doc folder of the SVN checkout, d'oh.

    Anyway - the setup I've got working (on Win7 no less) is:

    1) Cygwin up and running the extra dev packages set out on your website;
    2) Latest version of OBDII GPS Logger built from SVN;
    3) Set up com0com with Com4 on one side, Com7 on the other;
    4) Booted up the simulator in default mode - serial port /dev/ttyS6 (I think... will confirm later);
    5) Booted up the win app on Com4;
    6) Enjoyed some simulator goodness.

    Sim works, very nice! Next on the agenda is simulating some fault codes so I can start writing code to test against it....

    Cheers,

    Paul

    Yay! I'm glad it's working :-D

    Which software is your "win app on Com4"? I know my stuff works with scantool.net, but I haven't tried many others on windows.

    The sim does understand error codes, but the default plugin [Cycle] doesn't provide them. There's a cheesy "Error" generator that just spits out some errors [it also ignores the reset command], or the GUI one is a lot better.

    To get the GUI one: If you haven't already done it, just open cygwin's setup.exe and install the packages "fltk-devel" and "fltk". Then re-run cmake and rebuild [you may need to purge your whole build dir first, as cmake caches the fltk stuff a bit over-vigorously].

    To run it, use "obdsim.exe -g gui_fltk". I'm guessing you've already found the manpages, but if you haven't, the obdsim page [online here] explains how to use different generators

    Oops, tried to build the app again after nuking the build dir but had a make exception:

    Am I missing something else?

    That's ... odd. Looks like missing headers, or ... something.

    For want of being lazy, obdsim also builds just fine under MSYS/MinGW. I have a recent build here: obdsimwindows-2010-04-18.zip.

    I'll have to go and try what you're doing; as a whole I find Cygwin to be a suboptimal solution [you can think of it like linux is to winelib as windows is to cygwin], I'll try and install it later.

    I will take lazy! Have a result... GUI sim is up and running.

    Got some sample output from commands sent from my "app" (ok, a glorified console). This is the log output for the sim:

    Code:
    ATSP0
    OK
    >010C
    ?
    >010C
    41 0C 4D E2
    >010C
    41 0C 4D E2
    >010C
    41 0C 4D E2
    >010C
    41 0C 4D E2
    >010C
    41 0C 4D E2
    >010C
    41 0C 4D E2
    >010C
    41 0C 4D E2
    >010C
    41 0C 4D E2
    >010C
    41 0C 4D E2
    >010D
    41 0C 4D E2
    >010D
    41 0D 00
    >010D
    41 0D 00
    >010D
    41 0D 00
    >010D
    41 0D 00
    >010D
    41 0D 00
    >010D
    41 0D 00
    >010D
    41 0D 7D
    >010D
    41 0D 7D
    >010D
    41 0D 7D

    The first two commands I send are "ATE0" (echo off) and "ATSP0" (set protocol). I then send down 10 RPM reads, then 10 MPH reads.

    Interestingly, the feedback I receive seems to be "one command behind" - e.g. my first MPH request has a RPM value returned, and the first RPM request has ? returned (probably in response to the dubious ATSP0 command).

    Anyway, good enough work for going zero to hero in one evening I reckon

    Update: looks like it's the "ATSP0" that makes the Sim unhappy, leaving that out makes it return the correct results....

    Yeah, I don't honor SP right now. I'm planning on adding multiple protocol support and making SP do the right thing... eventually.

    Nice one.

    I've had a spare couple of hours over the weekend to fling something together.

    This app will eventually be a fully fledged WPF or Mono application (running on Windows, *Nix, and Mac would be nice!), but for now I've put together a console app to bring together the core functionality.

    Here's a peek:
