Re: [Flightgear-devel] Possible new .ac loader bug?
Hi, On Monday 23 March 2009 11:29:03 Stuart Buchanan wrote: I think I've found a regression in the model loading code. As part of the Vulcan cockpit , there is a display showing the current position of the control surfaces and trim settings (Aircraft/vulcanb2/Models/Instruments/control_pos.xml). It is the oblong box in the upper center on the Panel. After doing a CVS up and rebuild last week, it stopped being displayed, with no error message AFAICT even with log-level=debug. The root of the problem (from trial and error) is that the .ac file had an object Rudder, which collided with the Rudder object of the aircraft model itself. I suspect the problem is in the .ac loader code rather than the animation code, as the problem was reproducable even when I removed all the animations from the object. I suspect that this is a new regression, as the object displayed quite happily on a CVS build from two weeks ago. I've corrected it in the CVS Vulcan, by renaming the object in the .ac and .xml files, but the bug should still be reproducable with a Vulcan check-out from last week. I do not know why this did not happen before. So the problem may not be understood too good. But, it is well know to me that the animations are applied to the model and all submodels. This is something I did not like to implement, but that happened for some reason with the plib stuff and that was reimplemented with osg. There is a comment in the model animation code that states that this is something strange to do. But I guess that there are many configurations out there that rely on this property. There are many more surprising things in the xml format that has grown over the years. I do not remember what else, but at the time I implemented that in osg. I hit plenty of strange behaviours that are hard to implement in the animations code, and might be very surprising to model authors if you step on that. I have often thought about introducing a more flexible and consistent xml model format where such surprises do not happen anymore. We could probably produce more tight scenegraphs which would help culling speed. We could stop the need to flip all the ac models to a different axis orientation which will definitely help modelers to animate their models. We could rethink some animations semantics which is sometimes very slightly beyond that what could be implemented efficiently. Often the most interesting use cases would work very good. But due to having that stuff like it is I had to implement something that was not very efficient to do.

Hmm, I had hoped that this kind of thing is fixed by the introduction of the 'reference time' which should fix problems that arise from the FDM talking about an other time than the carrier. The problem then would be that the carrier is kind of 'already gone' or 'not yet there'. So does this happen at the same time than model loading still makes the simulation hang for some small amount of time? Or may be some other hint where I can search for that problem?

Re: [Flightgear-devel] Help: Building a binary IO driver based on Altas driver
Thanks for the reply Curt,
I took your comment onboard, Not much time today so I still have not
modified the process routine, but have instigated printf for testing. I wish
I knew it was so easy to so that earlier.My background in single chip
devices where there is no screen!.
Thus at the moment, the process routine calls the parse routine as in
yesterday, There I am picking up the number of chars in buf from
length. In the parse routine then I am testing each char and at the same
time sending the char to a printf.
If I test each char, from buf I can find 0x5a Z but not 0xA5. Futher the
terminal shows only the printable characters from buf. However it is a
steady cycle of the same pintable char data 10 times a sec with the non
printables missing.
From these 2 observations I suspect the non printables are not in the buf
array.
If I understand your response correctly, every time parse is called, buf
will hold fresh serial data and the number of bytes is in length, this may
not be the complete burst of data I send every tenth of a second to the
serial from my Pic. But if i gather these bytes and write them to an array
or file I will end up with a replica of the stream in. From that i could
find the sync bytes and recover the complete block of data.
However I realise once I have it working i need to refine the code a bit,
but if thats the case I seem to be missing the non printables.
You mention modifying the call to parse to call it only when its got the
full block of data. I would prefer very much not to be putting patches in
the other code outside of my sim file (cloned from the Altas one in
src/network), the only patch i have done is in fgio.c and that was to clone
the call for the atlas routine.
So questions
Firstly have i come to the correct conclusion above, and is it possible non
printables are not present in the buf data?
Could you tell me where in FG it calls the process routine for the various
io protocols? I seached today with out sucess, possibly from simgear?
Also the parse routine only seesm to run when i define serial in in the
comand line, where as I want the port bidirectional and would use bi in
the command line. eg, fgfs --sim=serial,in,10,/dev/ttyS0,38400 --httpd=5008
As i want to read in 8 bit hex data should i be looking at another method?
I apologize for dumb questions but I fully realize FG is quite a complex
piece of evolving code and I only want to hook in a small addon.
regards Harry
Below is modified to pick up char Z (ox5A) from buf and test as mentioned
above using lenth to read from buf.
It outs the 0x5A to screen and sets the gear property but cant finsd a 0xA5.
SGPropertyNode * node;
l =0;
while(l != length)
{
ch = buf[l];
printf(%c,ch);
switch (Msg_State)
{
case 0:// find the sync header byte 0
if(ch == 0x5A)
{
Msg_State++;
Msg_CS_OK = 0;
b5=false;
node = fgGetNode(/controls, true);
node-setBoolValue(gear/gear-down, b5);
}

Hi Harry,
I've only skimmed your example code, but off the top of my head here are a
couple things.
The FlightGear serial IO defaults to non-blocking. That means characters
will only be read if they are available, and you can't depend on the entire
message string being there when you try to read it. If you back up to the
routine that actually reads the data in, you may need to do some work there
to accumulate the entire message before handing it off to your parsing
routine.
One thing I do quite often in these situations is to add printf()'s to the
code that reads the data in. Seeing the actual data values or message
lengths that are read each time can be quite instructive.
Best regards,
Curt.

Could I ask for some help and advise on this issue.
I am trying to interface my Microchip Pic based sim hardware to FG. I have
it working with a genetic string but the string is becoming to large for the
pics to handle, also I would like a crc or check sum on the data. Thus i
prefer a compressed hex format. Ie the pic sends 4 bytes sync,16 bytes each
bit being a switch boolean, 16 bytes each being an analog setting then 2
bytes with each bit being a sign on the 16 analogs.
The format thus is A5 5A A5 5A hh hh hh hh hh hh ...for 40 bytes.
For simplicity I opted to clone and adapt the Atlas driver, keeping in
line with all existing FG conventions. and use it as a frame. and intigrate
my driver into FG when i build.
So far I have bumbled my way along, I not a good programmer but have
learnt my way around C with the microchip C18 to drive all the hardware. I
have managed to generate and output a binary compressed message from FG. But
cant seem to get it to decode on the inwards stream.
My approach is similar to the way i run the can bus between the hardware

However digging again into it ( the strange behaviour) , i suspect, now, that it could be coming from my gears definitions which introduce some random oscillations, only when i land ( again) on the Carrier. To conclude, forget the noise, at least, until i will have found i my side the origin of the problem. Well, well, I have found the error The problem was not groundcache related , it was gear parameter which did not suit to ( the tuning is very sensitive ) . in addition to it, i had an error with the terrain detection , then, the aircraft thought that it was in water with a huge drag.

Why not, the real ones have island solid , that is more realistic. I have tested on an other Carrier ( straight deck Arromanches ) the arrester Net ( not sure about the word) which can be used in case of emergency. that new groundcache is very useful for it. except if i change airport as said before.
