Been a long time proponent of this sort of thing, and in these days of 'shiny' tablets etc it is unusual not to have some sort of official output protocol in a flight sim

Yes the data Artist points to is what is needed- infact CoD has many more types of data that is readable than old IL2 devicelink.
I've messed about with coding based on that to do 'speedbar' type readings of various parameters but that's about my limit of coding- hacking other peoples work:sad:
One of the 'tricky bits' of coding required is to 'translate' the request packet from say udpseed into an answer packet from CoD
Not only are there instrument reading parameters available but also many other useful ones- for a full list see zip in 1st post
http://forum.1cpublishing.eu/showthr...338#post342338

Apart from deciding which CoD parameter is most relevant as an output (gauge users will want instrument readings whereas performance chart makers will want 'absolute' values) some values might need converting to the relevant units

The more I look at what is involved coding wise to export this data via udp, the more I realize that it's beyond me:oops:

If anyone gets to do this a more MKI version of this would probably be my first project:D

Thanks for the link, but the app on that page is for the original IL2 series that uses device link. It's relatively easy to set up a client program to poll device link using the UDP protocol and retrieve the information.

COD is a different kettle of fish.

As stated beore I tried to use a C# script to set up a UDP server wfrom within COD but due to my limited C# scripting skills failed.

Anyone else had any luck?

Could be that there is another way to get the info out of cod. I guess we need scripting documentation for COD.

Cheers

If this becomes doable?
I'd jump on it in a heart beat.:grin:

Hey! As a developer I have to object here... ;) You call C# smelly compared to Delphi that is really Pascal++? And why use Delhi at all for devicelink coding against IL2 when you can use C++?

It really is a shame - there is all that information in getParameters and yet there is no official info on how to utilize it. I am busting to get my motion platform cockpit working with CoD. It works great with IL-2 and Devicelink, but why does getParameters have to be so complicated with no clues about how to use it?

:) Just what I had at the time! :) But your right 'Real Men' program in C++.

so what exactly do you need to be able to use the data accessed by the simhq guy, to be able to use it for your gauges ? if some limited form of data is already accessed for them to create the displayed data for heading and altitude, shouldn't it then be possible to translate that to a format that some of the gauges can use ?

btw, isnt it also possible to have some very limited 3D version of the gauges so it avoids the 3D/2D problem you mentioned before ? with most gfx cards having multiple connectors these days and the minimal GPU resources needed to display a 2 color static image i would have hoped we dont need to run a 2e pc to just display the 2e screen with the UDP method. err, please be aware i know nothing of programing, so i am probably overlooking some obvious reasons why some of this is an issue :)

The easiest way would be for CoD to output 'old style devicelink' outputs.

This would entail the CoD script doing:
1) reading the request packet sent from udpspeed,
This bit would probably need to read from an ini file to set up the IP address and port
2)ordering the data from this packet into an array or similar.
This could be simplified/eliminated IF the contents of the packet is a fixed, known set say for a BFP gauge set using~ 10 parameters.
A more universal system would be better tho.
3)Then each parameter must be associated with the relevant CoD parameter and read this data, There is a problem in converting units as IAS is given in km/h in Luft AC and mp/h in British AC. Doable in code but another complication:rolleyes: Indicated ASI is also possibly nit accurate
4)write this converted data into the reply packet
5)send it:cool:

that's my take on what needs to be coded- actually doing it is beyond my talents :(

this is the nearest example of something similar i've found
http://msdn.microsoft.com/en-us/library/tst0kwb1.aspx

http://tools.ietf.org/html/rfc768
shows udp protocol

devicelink doesn't use checksums

anything is possible:) An MG produced program that displayed the 'wondewoman' gauges- (editable, reposition/sizing ability, saveable profiles,...) would be nice as a free bonus in the sequel:P
As to wether modern cards won't affect fps i couldn't say for sure (4 yrs ago with IL2 it was definately a problem)

I for one, Support this Thread!

I hope the devs gives this a mind. With the complexity of the engine, this would likely help reach another niche of the market too.

Please, do go on, Gents!
