    Hi all, i'm trying to communicate to a COM1 to two servos.

    As rNr chair i need the instructions have a simple format consisting of a sync byte (always ASCII 255), the servo number (0-254), and relative position (0-254, where 127 is centered).

    I cannot find the synthax to use universal serial output to send the appropriate three bytes (unsigned chars in C parlance).

    From rNr i thought it should be ~255~~0~~x~ but it doesn't work. Also i've applied a 127 sum on byte char x variable.

    Any help would be great, i'm really stuck.

    Hi sirnoname!

    Thankyou for your work/help! I'm using x-sim public 1.6.9. For now i didn't plug any game. Just started profiler and tried to move servos through sliders above (move simulator) button. I get target.x update but none value update on simulator X value....

    where can i find new version to download? Should I have to update to 1.8 through PLUGINUPDATE.ZIP? Could I apply to x-sim2 beta testing? :clap:

    should this synthax be fine?

    ~255~~1~~x~ (without caps?)

    Cheers

    How fool i am!!!

    The problem was that i didn't push (START) Button!!

    Now i'm talking to 1 servo, i'm going forward to talk to second axis and get some input from LFS force sender.

    I can't wait to see the servos working like on rNr simulation vr simulation!!

    Cheers

    When I've connected my first DIY RnR circuit board to the Profiler, I've made the same error.
    But in my case, I've resoldered nearly each part (including the smd ones) onto the circuit board once again before I've noticed the 'start' button :lol:

    Have fun!

    Regards
    Christian

    I've nearly cum...

    It's really nice when you see the job done on x-sim working out servo movements with washout and all. Nearly 3 years ago i did some vb programation around LFS that got out gdata to servos, maybe a page of code. I wonder the quantity of time being developed on this one!

    I will be looking to rocking promise of beta2. Is it going to be able to do some 6dof? it would be great to see some geek working out that stewart 6dof project 10 year old code...

    Again, it's been a pleasure to play with it. Hope be able soon to show some footage.
