    No wait I spoked to fast.

    With “Use simtools order” The idea was to use the following mapping right?

    Something is still mixed up. Could you doublecheck it?

    I thought you will modify the dll for that purpose

    :think:confused: Give me a minute...


    The idea was to also change the order in the interface, so I didn't change the DLL.

    EDIT:
    OK, found the problem.
    When I tested, I think I forgot to change order in SimTools axis assignements.... So there was no error.
    New build on the way.

    Your yaw could be inverted but that’s cosmetic.

    It looks coherent. It seems you nailed it

    New version in 2 minutes.
    Not the yaw, but picked an old code with auto gain for the actuators...

    Version 1.7.7

    In the first post...

    -Now we can see the serial data sent without connecting a board.
    -Grabbed an old code that auto tunes the actuators gain. This avoids clipping on the rig.

    It was a first test to look for a complete auto calibration.
    Before auto calibration:
    anotdjusted.jpg


    After:
    adjusted.jpg


    How it works?
    While activated, the auto tune decreases the gain, each time the rig is out of range.
    So to use it, increase gain and press the button.
    Make a lap in a car sim or an air plane without big spikes.
    When you see that there's no more adjustment done in gain, stop the auto adjustment.
    You can now increase the gain a small value, taking into account that the spikes that generated the value are something that occurs sporadically.

    It's not avoiding clip in the pose components (maybe in a next version), but on the complete rig.
    Clipping in the pose components, should be treated with the filters.

    Sorry Still a big problem on my side.

    The working 1.6.8 loks like this:
    FlyPT Hexapod Interface 1.6.8.png

    Here are the not working Versions:
    1.7.5:
    FlyPT Hexapod Interface 1.7.5.png
    Same problem as in 1.7.7, but more red lines ;o)
    FlyPT Hexapod Interface 1.7.7.png

    When i copy my old 1.6.8 in the folder, it works normally.
    But the 1.7.5 and also 1.7.7 the rig is going in lowest position even if the box is not checked.
    No movement also from SimTools.

    Kind regards

    I'm taking a look... but it's strange, not even SimTools?
    Try to run the new version in a different folder and see if you are asked for permission to run it.
    Be sure that there's no setup file in that folder.

    Yes, there is always the question at the first start.
    Also on the 1.6.8, but this one works
    Every time i copy the different versions into the same folder.
    Also in a new folder.

    OK, from the images I think the problem is on the changes I made to calculations.
    Can you show me the rig measures. I want to reproduce the problem.
    And SimTools, are you able to connect it to the interface?

    I´ve tried a complete new Folder and Setup and get the same not working result.
    Here are my rig dimensions

    If I may interfere again, I think it’s valuable what you are implementing however it should be switchable with a checkbox so the user has the freedom if he wants to use it or not.

    As you managed the kinematic, the scaling and the consistency in the interface which are the basis, everything on the top of it should be an selectable additional feature.

    It's a checkbox with button style.
    Red=Active
    Normal=Inactive
    I'm correcting an error for @C1500 and I will change the style to traditional checkbox.

    In first post...

    Removed a comment in the code that was allowing angles bigger than 180 or less than -180 (@C1500 problem)
    Changed auto gain to check box classic style

    @C1500

    You can use the following settings:

    If they rotate in the wrong direction, try to check "Output swap swapped"

    Hi FlyPT
    1.7.8 is working great
    Thank´s

    But, "Output swap swapped" is not working for me
    with my settings the "heave" is working good up and down.
    If i use your settings with swapped, the rig turns left and right instead of not up and down.

    Kind regards

    Sorry,
    misunderstanding on my side.
    To swap the swapped swap, swaps it to the right swap. *lol*

    It works great with the checked "Output swap swapped" checkbox

    Thanks and good night ;)
