Re: [Flightgear-devel] sending external fdm data in the form of UDPpackets
Hi,
I am using FGFS 0.9.10.I tried sending FGNetFDM structure(given in
net_fdm.cxx)(after doing htond or htonf) from one computer to another
computer running Flightgear but couldnt get it running. I tried Packet
Analyzer to check whether packets are reaching the particular PC or
not.Ifound that packets are reaching the PC running
Flightgear.Is there anyway I can verify on the destination PC that the
packets are in correct format...Can anyone provide me with sample UNIX
program to run Flightgear from external fdm data in the form of UDPpackets.

Hi!
Well, when you have used hton*() on your struct it should (hopefully[1])
have the right (i.e. the one you should send) represantation in memory so
you can just reinterpret your struct as a char array of the right form:
typedef struct {...} mystruct_t;
mystruct_t anInstance;
char * sendbuffer = (char *)anInstance;
This pointer could then be passed to sendto(2) or similar.
[1] The critical point here is to be sure that the compiler does not
insert any padding into the struct. Alternatively one could manually
and explicitly move the contents of the struct into a char array to be
sure it has exactly the right form (this is what I would do since
it also documents the actual packet format a bit more clearly).
Cheers,
Anders

Hi Umesh,
That printf() is quite unlikely to produce anything sensible (and unless
there is a 0 byte somewhere in anInstance it might try to print your
computers entire memory..). Us telling the compiler that it
should consider anInstance as an array of char:s does not mean that it
becomes a zero-terminated string that we could give to printf.
To determine whether anInstance got the right format or not you should
test to decode it with the same code as FlightGear uses. Either by copying
it to your application or by tracing fgfs or adding some temporary
printouts to it. (I'd do the latter as that would also tell me whether my
UDP-packets got through at all.)
But I cannot see any data packets formed.Is that i am using wrong format for
printf or is the problem with something else!Please help!
I have a simple application that sends UDP packets to FlightGear here:
http://www.gidenstam.org/FlightGear/HeadTracking/
However, it does not talk to NetFDM but to a head tracking component that
only exists as a patch somewhere at the moment.

Re: [Flightgear-devel] Modeling a Flexwing Microlight
--- Joacim Persson wrote: On Fri, 8 Dec 2006, Stuart Buchanan wrote: - There is no trimming for different flight phases. Vertical speed is purely controlled by power. Many trikes has a trim function, just like all non-trainer hang glider has nowadays. Many do, but mine doesn't :) Even by microlight standards, my aircraft is very basic. My panel has 5 instruments: ASI, Altimeter, Compass, EGT, RPM. Plus a stopwatch stuck on with velcro... However, I am talking about a directly controlled pilot-controlled trim system rather than the side-effects of the wing flexing. (I know the Airborne trike we use for aerotowing has it.) This trim is usually operated by a line, the trim line, which is drawn to the speedbar (on a HG) or on a sidebar (on a trike) and most noticeably it adjusts the tension of the cross beam (which is divided in two parts connected with a hinge at the centerline). (Compare with the kick or sheet on a sailboat mainsail.) There are however more functions coupled with the trim than cross beam tension. On kingpost HG's (like your trike), there is something called luff lines connected to the trailing edge via the kingpost, on the newer topless hg's there are sprogs at the wing tips filling the same function. Luff lines and sprogs act like an elevator trim under certain circumstances, and is primary a safety detail to prevent an uncontrollable dive. The setting of those are also altered along with the trim setting. I believe I can alter the luff lines on the ground, but I doubt it is something I'll be doing in the near future. The cross-beam isn't fixed to the keel. When the wing is un-folded a pulley system is used to pull the crossbeam into position and tie it off against the keel, but I guess it will still have some lateral movement. I didn't know that trim affected the cross-beam. I So the trim on a HG or trikes changes: 1. The camber of the whole wing. (cross beam tension) This affects L/D ratio, stall speed. 2. Apex (follows from sail tension) and dihedral (not much). 3. The elevator trim function of sprogs or luff lines. Your trike may have the cross beam fixed to the keel (can't tell by the photo) and would then be a bit stiffer in handling (but more course stable) than a hang glider with the trim fully loose, but with a floating cross beam (i.e. not connected to the keel) as all hang gliders have today, the first effect of moving the weight to one side (shifting the keel sideways with respect to the cross-beam and wing tubes) is that the wing you move away from gets less camber and the other gets more camber. This in turn makes the outer wing tip fly a bit faster than the inner wing tip, generating some rudder and aileron effect. A hang glider with a non-floating cross beam is rather slow in turns. This difference in camber between the wing halves is less the more the pilot tighten the trim. So we can add a fourth function of the HG trim: 4. Sets the amount of rudder and aileron effect from shifting weight sideways -- indirectly by adjusting the cross beam tension and thus the difference in tension of the trailing edge on each wing half. In short: when circling thermals or coming in for landing, you release the trim, when flying straight between thermals you tighten the trim (fully or to a wanted trim speed). But that is perhaps a bit beside the point -- a trike pilot doesn't have to worry much about L/D ratio, and there is plenty of weight for steering with pure CG shift on a trike. So, should I use YASim or JSBSim for this project? Or larcsim? The only hang glider model in FG (airwaveXtreme150, a larcsim model) has an invisible motor+propeller attached to it, so we could call it a trike. It doesn't have a trim function anyway. (I'm quite sure the original has.) I did consider using larcsim, but decided not to on the basis that it is no-longer developed much (if at all). ___ To help you stay safe and secure online, we've developed the all new Yahoo!

I was told they're afraid of running into the hassle of reworking half of their interface with every new version of FlightGear, because the interface actually is not what people would call a stable protocol. The biggest issue is that people with proprietary software on one end get locked into a specific version of FlightGear because as FlightGear evolves, their proprietary tools can't or don't follow very quickly. That said, the most recent version of the aerospace blockset for simulink supports multiple versions of FlightGear including v0.9.10.

No, say whatever you like, joking or not, and I'm not offended. There isn't a single one-size-fits-all communcation protocol. That's why we have several mechanisms available in FlightGear. The NetFDM is perfect for certain situations and applications, and completely the wrong approach for other situations. There is some work (moving very slowly because involved) to create an xml specification for a binary protocol so an external application can feed flightgear an xml file to produce binary output matching exactly what that external app wants and expects.

I don't have the ability to personally test a lot of combinations, but yes, this should all work well as of v0.9.10. Endianess is definitely handled. And even for 32 vs. 64 bit systems, they all still use a similar convention where integers and floats are 4 bytes and doubles are 8 bytes. As long as we confine ourselves to ints, floats, and doubles (and use an int for boolean values, etc.) then we should have an extremely high probability of getting any two machines to talk to each other successfully. I do know of one exception ... the X-Scale architecture seems to swap the first 4 and last 4 bytes of doubles, so they aren't using a standard big or little endian representation for double floating point numbers. But if you know that in advance it's pretty easy to work around (since you will be running your own code on this processor, not flightgear.)

[Flightgear-devel] Fw:Filenbsp; I/Onbsp; problem:whynbsp; ca n'tnbsp; replaynbsp; mynbsp; flignbsp; ht nbsp; innbsp; 10hz
I want to replay my flight,read the flight path information from a file. Fist,I record a flight path at 10 hz,5hz,or 2hz ,just like this: --native=file,out,10,flight1.fgfs and then I relay my flight,but I got a secction error! --native=file,in,10,flight1.fgfs --fdm=external but if I set ,just 1hz like this,that's ok! --native=file,out,1,flight1.fgfs --native=file,in,1,flight1.fgfs --fdm=external why,is it because fgfs can't read the file at more than 1hz,it's too fast? otherwise,if I set like this: --garmin=file,out,1000,flight1.fgfs then I replay it,use --garmin=file,in,1000,flight1.fgfs --fdm=external it' ok,but the image is dithering.why? Is it because I should set the hz=a very large number 年 末 数 码 1 0 0 元 专 场 ( 图 ) 百 种 数 码 精 品 1 9 元 起 1 0 0 元 封 顶 , 不 抢 真 的 悔 死 你 ( 图 ) - Take Surveys. Earn Cash.

Been working on an engineering data panel to show live gauge representations of important engineering parameters.

The blip at the end shows a sky rendering bug with the latest OSG. :-) Looks similar to what I've posted earlier: http://www.mail-archive.com/flightgear-devel%40lists.sourceforge.net/msg06962.html http://www.mail-archive.com/flightgear-devel%40lists.sourceforge.net/msg07123.html Would that be on NVIDIA with driver 9629 as well?
