But I'm already sending a 3 decimal digit number to fgfs!

Re: [Flightgear-devel] Generic Protocol Input - Float weirdness
Others? Who? Where in the code should I look for it? What should I search for? Me ;-) But even simpler for the microcontroller: the internal representation neither khz nor mhz but channel. For the COMM, channel 0 is 118.000 Mhz and channel 759 equals 136.975 MHz. The formula to convert from frequency to channel is Channel = (Frequency_MHz - 118.0) / 0.025 and from channel to frequency: Frequency_MHz = Channel * 0.025 + 118.0 For the NAV radio, the formula is Channel = (Frequency_MHz - 108.0)/0.05 and reverse Frequency_MHz = Channel * 0.05 + 108 resulting in channels from 0 - 199. You only need a uint8_t (8-bit) variable for the NAV and a uint16_t (16bit) variable for the COMM part.

[Flightgear-devel] OSG caching (was: Texture cache)
Maybe someone could do some tests when changing the setting (SGPagedLOD.hxx:56) from CACHE_NONE to CACHE_IMAGES or even to CACHE_ALL (then recompile/install sg+fg). Would be interesting to know how this changed loading times, run-time fps and memory consumption. After 30 minutes more of testing: It also works in practice. I have seen no averse side effects, and the performance drop from loading new clouds is now almost completely gone - the framerate drops I still see are mainly associated with terrain sampling. The actual rendering performance is, as far as I can see, not changed, i.e. once everything is there, it is there. But all in all this makes things way smoother. It should be most pronounced on single CPU machines. I've also been using CACHE_ALL since then - not seeing any problems. But I haven't checked memory consumption.

I like your hardware approach, getting your hands dirty on a naked ATMega16 should be fun too :-) It's interesting, and results in *much* smaller code than you'd get using the arduino libraries, and I was reasonably happy with gcc anyway which reduced the learning curve. It's nice to be able to just type make and have the code compiled and blasted onto the chip via an AVRISP2.

Re: [Flightgear-devel] Generic Protocol Input - Float weirdness
Ok Torsten, let's resume. You suggest: Send this as an INT with the generic protocol and use offsetA/offset factorB/factor within your chunk But then: typeint/type that's the nature of an INT: no fractions at all :-P I don't see a way out. - I send an INT to FGFS, the ((value_on_wire * factor) + offset) calculation gets me an INT without decimals. - I send a DOUBLE/FLOAT to FGFS, the ((value_on_wire * factor) + offset) calculation gets me a complete DOUBLE/FLOAT but with far too decimals. I repeat myself, maybe I was not clear: - FGFS stores correctly 3 decimal digits double values in the property tree when changing the standby-mhz value pushing the mouse button on the 3d elements in the simulator window (it never stores more then 3 decimals!); it does that right. The action in kx165-1.xml does a simple step-up/down but gives always 3 decimals, never more than that. - It does that wrong only when I update the value sending it with the generic protocol, even though on the wire I send precisely 7 digit numbers: 3 digits followed by a dot and 3 decimal digits); that num,ber gets almost always changed to a longer number, with more decimals (not zeroes). Hence no way to make it work as It should :-( It seems there's no way out. - I hope I did not confuse you all with my use of the term Decimal which probably was not appropriate. I realize now english people say fractional. I'm Italian, to us a number is made of an integral part and a decimal part. A number like 137.750 is made of: 137 = integral part, 750 = decimal part. I'm not used to use the term fractional part. I realize now only that me talking about the decimal part of the frequency value may have mislead quite a bit.

Re: [Flightgear-devel] Generic Protocol Input - Float weirdness
Roberto, though on the wire I send precisely 7 digit numbers: 3 digits followed by a dot and 3 decimal digits); As you describe correctly, you're transmitting strings (= series of ASCII characters). typeint/type For an input protocol this is the _target_ type. With int your _string_ is parsed and converted to an _integer_. No fractions. Keep sending strings representing integers (no dot . characters in the string) but specify the _target_ typedouble/type, using offset/factors as described by Torsten. FlightGear will then parse your string, convert it to double precision floating point, and apply factors and offset. Make sure you're using FlightGear 2.2-pre-release or the current GIT version to achieve double precision. FG2.0/1,9.x only supported single precision with the generic protocol, so there was no difference between float and double. This is the commit which made double precision work for the generic protocol, and it was not part of FG2.0 yet: http://www.gitorious.org/fg/flightgear/commit/d0f6f748ed7a2ad34159e18d352e4df6c11e2cde cheers, Thorsten -- Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
Re: [Flightgear-devel] KX165 - serially feeding data to increment a property value. How?
I think you're really beating yourself up the hard way. ;-) My suggestion: get a board from http://www.diolan.com/i2c/u2c12_doc/u2c_spi_config_ss_fun.html and 7-segment driver chips from Maxim (7219) with an SPI interface (drives 8 alpha-numeric per chip) or a Maxim 6954 that drives 16 alpha-numerics or any combination of discrete LEds. Run the chips as slaves on your SPI bus and the diolan board as a master. ATM my 747 sim has over 37 discrete alpha-numerics (MCP, nav/radio panels, digital clocks, etc)- one master, (1) 6954 and (3) 7219s.The 737 that was delivered to NASA/Ames two years ago had a comparable number plus 54 discrete LEDs for warning lights, annunciators, etc Use the Network code in FG as examples on writing a socket connection and write a small program to run your hardware and connect to FG over a LAN.

Also most of the no image file, .. errors go away if I specify paths to them in the effect that inherits the one from Effects/reflect* (inheritance problem ?). No, it's not inheritance problems. It's people using unchanged copies of code which is meant to be an example. But I think I can fix it. In any case, the warnings shouldn't affect the functioning of the shader. Vivian Ok.. so the reflect.eff in $FG_ROOT/Effects is only meant as an example ? It should say so. Instead it says it can be inherited. That's not what I meant. It was the use of Aircraft/737-300/Models/Effects/733LH.ReflectionMap3 when it is not appropriate. Reflect.eff can and should be inherited. Nevermind that, if I inherit it in an .eff, shouldn't the unchanged elements be passed to the other .eff ? Yes, and as AFAIKS that works correctly. I have amended data/Effects/reflect.eff so that it uses a generic example reflect map, which needs replacing for individual aircraft. There is one remaining error message which can be generated: failed to load effect texture file D:/path/to/your/data/ This slightly misleading error message is generated when the object that has the reflection effect applied has no base texture. The effect still works as expected though. The fix is obviously to apply a base texture.

Vivian I see, I think i've got a couple of those in the IAR cockpit that might give me that error : If it's not too much to ask will you take a look at this: http://code.google.com/p/flightgear-bugs/issues/detail?id=262 It's very visible in the IAR cokpit.

Re: [Flightgear-devel] Calculating free stick position and forces
On Fri, Apr 1, 2011 at 12:38 AM, Jon S. Berndt jonsber...@comcast.netwrote: Actually, Alan is correct, as Ron also mentioned in the JSBSim-devel list, where this topic is cross-posted. I think it is quite possible that we can already do this using function definitions in the aerodynamics section of an aircraft spec. file. There is no perceptible performance hit to using function definitions. The functions are implemented in C++, are fairly efficient, and calculations are cached per-frame. I'd prefer not to see possibly type-specific hard-coded calculations going into the codebase - I think we can implement this in the current codebase using existing capabilities. Jon I agree, there are already enough tools in the config file for defining the stick force. But how can we trim the stick force? Would it be possible to use the autopilot functions? or a new trim mode is needed in the code?

[Flightgear-devel] 答复: SimGear Compiler Question in VS 2008 Express
So I don't know where is the simgear_config.h file? Maybe that is generation by compiler.
