     For C/C++, with just access to an offset, it must be polled to detect when a button changes.  True?

    Yes! You could, of course, write a wrapper around the provided functions to implement a callback mechanism if required...

    4.974 is the latest supported version, however there is a version 4.974b which contains an improved Lua ext library (see the 'Updated Modules' support page:

    ).

  2. Hi Morten,

    as according to the manual, one is not supposed to mix  "send direct to FSUIPC Calibration" and  "FS as normal axis"

    what did you see this? Its fine to send one axis to "send direct to FSUIPC Calibration"  and another to "FS as normal axis". Of course, each axis itself can only have one destination.

    Can you also check that you have the controllers in P3D disabled (maybe they became active again after your P3D update?).

    There is no “front wheel” control used in FSUIPC. You may be able to use the FS control “STEERING SET” which I think was new to one of the releases of P3D and so never used by FSUIPC in its controls. Steering on the ground has always been by rudder operation, hence the blending between the steering tiller operation and the rudder.

    “Sharp turns” in a PMDG 777, or really any airliner, need low speeds, and judicious use of differential braking and, yes, occasionally asymmetric thrust (as the aircraft slows even more during the turn). I don't fly PMDG aircraft, but maybe some other PMDG users could help you out here.
     
    I'm actually surprised that using “send direct to FSUIPC calibration” on any PMDG Boeing airliner works at all. Those tend to read the control values themselves direct from Simconnect, whilst FSUIPC is calibrating them and sending (possibly different) values at a much lower Simconnect priority level (to avoid an infinite loop). This generally give unwanted jerkiness.

  3. Hi,

    is this still an issue?

    you have the same Joy id number (2) assigned to both your wheel and throttle, but I guess you already know this. What do you mean by ' I have tried using the JoyIDs but without help'?  What is your issue with JoyIDs?

    You can also try editing your INI file to assign a new Joy ID number, as explained in this (and other) post:

    Cheers,

  4. Hi Robert,

    As Chakko says, the ambient pressure doesn't change very quickly, which is why you are seeing slow updates. If you monitor offset 28C8 and go into slew mode and slew up very fast, I see the following logged:

      1115813 Monitor IPC:28C8 (FLT64) = 2071.1340
      1115813 SimRead: 28C8="AMBIENT PRESSURE" [also 28E8]
                FLT64: 2071.13404498

      1115891 Monitor IPC:28C8 (FLT64) = 2070.8867
      1115891 SimRead: 28C8="AMBIENT PRESSURE" [also 28E8]
                FLT64: 2070.8867444

      1115985 Monitor IPC:28C8 (FLT64) = 2070.6393
      1115985 SimRead: 28C8="AMBIENT PRESSURE" [also 28E8]
                FLT64: 2070.63931635
      1116078 Monitor IPC:28C8 (FLT64) = 2070.3920
      1116078 SimRead: 28C8="AMBIENT PRESSURE" [also 28E8]
                FLT64: 2070.39201578

      1116125 Monitor IPC:28C8 (FLT64) = 2070.1446
      1116125 SimRead: 28C8="AMBIENT PRESSURE" [also 28E8]
                FLT64: 2070.14458772

      1116219 Monitor IPC:28C8 (FLT64) = 2069.8974
      1116219 SimRead: 28C8="AMBIENT PRESSURE" [also 28E8]
                FLT64: 2069.89741462

      1116297 Monitor IPC:28C8 (FLT64) = 2069.6500
      1116297 SimRead: 28C8="AMBIENT PRESSURE" [also 28E8]
                FLT64: 2069.64998657

     

    The interval here varies between 80-100ms.

    Note that there is a delta value set on 28C8 (i.e. changes less than this are not reported) of 0.00009F, which should be fine.

    With further tests, also monitoring/logging 3498 (ambient pressure in millibars) and the altitude (6020), it looks like the sim is only updating on millibar increments above 0.12-0.16 or so (or about a metre).

    Interestingly, slewing down slowly (Z) seems to go at a rate of about a meter per second, logging the ambient pressure roughly once per second, while slewing up slowly (F3) seems to go at about 15m per second, logging the pressure around 12-15 times per second.

    In summary, I think the rate is down to SimConnect rather than anything in FSUIPC5.

    Cheers,

  5. Hi Tom,

    where does it say that it is a 'Beta copy'? There is no such thing! Version 5.121a is an interim version and is out-of-date (not supported) - please download and install version 5.15, which is the latest version of FSUIPC5.

    There are only registered and unregistered versions (and no expire date!). The 'About' tab in the FSUIPC5 main window will show if the copy is registered or not, and the FSUIPC5.log file will log the registration check (when you start P3D). What does this say?

    Cheers,

    John

    P.S. For future reference, could you please use a more useful topic....'FSUIPC' doesn't say much, 'FSUIPC registration query' would have been better! Thanks.

  6. Hi Don,

    you can connect your USB devices to your client computer and connect using WideFS. This will generally be fine for buttons/switches/toggles, etc, but for axis controls (throttle, elevators, ailerons, rudder, etc) you may find the added delay (due to the network) gives poor response times.

    Anyway, Pete will be back next week so please wait for his opinion before you splash the cash!

    Regards,

    John

  7. Hi Luke,

    there were some changes in the way the sim mode is derived that were introduced in FSUIPC v5.15. See note 5 in the 5.15 history document. There were also some changes in the use of offset 3365 (which is the 'in-menu' or 'dialog' flag) in v5.14 (please also see History document for details)

    The sim mode is now taken from the PDK and stored in offset 3402 as a bitwise flag. Please check the offset status document for this offset. There is no change in offset 0628 - this should still be 1 when in instant replay mode and 0 when off.

    Cheers,

    John

     

     

  8. Hi,

    unfortunately it is difficult to tell what is in the attached image, but yes - the 'Previous Flight' should be visible in the 'Load Scenario' dialog box.

    I am not sure why the 'Previous Flight' is not visible, if it is there and visible in the 'Save Flight' dialog box, it should also be in the 'Load Flight' one....

    You could try activating the 'Provide menu entry for flight loading' option, in FSUIPC's 'Miscellaneous' tab. This will give you an extra 'Load Flight...' menu option in the 'Add-ons' drop-down. Use this to navigate to your saved flights directory (usually in the Documents/Prepar3D v4 Files directory of the user account - this should be the default) and see if you have the 'Previous Flight.fxml' file there and try and load that.

    Cheers,

    John
