777 SDK CDU information?

[ahuimanu 50]

One nice thing about the new 747 SDK is that we have access to the CDU data.  Do you foresee this feature being added to  the 777 SDK (or perhaps even the 737)?

Thanks

Are you sure the data is not there? That was the issue the guy that interfaced the Engravity CDU with the PMDG aircraft's had (https://shop.pollypotsoftware.org.uk/engravity-cdu-pmdg-interface.html) but with some SP he was able to make it work for all 3 (NGX/777/744)

Hi Jeff,

The 737 SDK already contains the necessary information to access the CDU data. This information is (or at least was) missing in the 777 SDK, but it nevertheless worked the same way as with the 737 (just replace 737 by 777 and add the center CDU). I asked for and received permission to use it that way.

thanks,

i only saw it documented in the 747 SDK and I didn't peek at the 737 in depth as my project would not focus on it.

 

so the data can be extracted in the same manner as the 747?

Hi Jeff,

I am pretty sure it works the same way as the 747. Unfortunately I cannot check that, because I only own the 737 and the 777. The 747 is on my wishlist.

Thanks Maarten.

The process is well documented in the 747 SDK whereas not at all in the 777 SDK.  I just need to brush up on my Win32 stuff.  When you guys do a GUI in Win32, are you using the straight API or MVC or what? 

Or, has anyone developed a managed .NET interface? I know that PMDG uses SimConnect, so can we create managed classes and structs to mirror those in PMDG_747QOTSII_SDK.h and otherwise use the managed interfaces that Lockheed Martin provides in the latest SDK?

I'd find the managed/.NET workflow to be easier overall.

Hi Jeff,

I'm using WPF and C# and a modified version of a managed SimConnect library called the 'Beatles Blog SimConnect' library. Unfortunately this library does not seem to be available any more. LM's managed library looks similar, but since I have everything working now and I am able to connect to both FSX and P3D, there's no benefit for me to convert to LM's library.

You need to set up the proper data structures and use the SimConnect_RequestClientData function. The 737 client data area is called  "PMDG_NGX_Data", the 777 client data area is called "PMDG_777X_Data" and I presume that the 747 data area is called "PMDG_747X_Data".

If you haven't done any SimConnect programming before and if you are new to GUI design, don't underestimate the amount of work needed (several hundred hours at least) to get a working data connection and a GUI that presents the data properly and is able to act appropriately to button presses. If you need more information, please send me a PM.

Hi Maarten,

The P3D v4 managed SimConnect Library/Class looks similar the Beatle's work: http://www.prepar3d.com/SDKv4/sdk/simconnect_api/managed_simconnect_projects.html

I'll PM about the other topics. I feel very comfortable with C# and the .NET environment and, in a former life, I was fairly comfortable with C/C++.  I always found the Win32/MFC stuff strange, so I usually avoided it.
