    Hi everyone,

    I'm trying for first time this, is a 2 DOF with an Arduino.

    I communicate SMC3utils with my Arduino and sems to work, the motor move and
    the potentiometer works. But, when i try the output test in Game Engine, it doesn't move anything.

    My comport is 5 and I use Windows 11 Pro.

    SimTools is 2.6 version.

    Please make sure that the SMC3utils app is closed before using SimTools, or it will not be able to connect.

    Yes, I restarted the PC but still not working.


    I should mention that I only have one IBT2 for testing. Maybe that affects it?

    Should it only work with one driver?

    Yes, I patched LFS with GameManager, and that one conect with Game Engine, I can see that red square turn in to blue.

    Maybe need to detect all the potentiometer?

    Please configure a Default Porofile and report if Output Testing works as expected.

    Thank you, finally works.

    I think that the problem was in potentiometer, because when it goes to 0% or 100%, all gets down.

    Some times, when potentiomer shakes goes to 0%

    I change the potentiometer and all is working.

    Thanks guys.
