Thank you.
We'll release the 757 SDK after the 1.1 is out.

Hi all,

I have been able to hunt for all LVars and have successfully been able to program all buttons on the MCP. However, I am having real trouble with assigning LVar data to dials. Could someone please help?

I am attempting to make a module and release it (with the permission of Captain Sim) for VR Insight users to add that extra dimension when flying.

I have managed to assign buttons with LVar data, but dials (SPD/IAS, HDG, V/S and ALT) don't seem to work. (Captain Sim Developers) Have you used offsets instead and is there any way you could tell me what they are? Possibly send a quick message over to me? (I have two weeks off from work so have some time to write some code).

Many thanks for any help. It's greatly appreciated as I'm 100% into this aircraft! It's amazing!! A big thank you!

Pete

That's great! Many thanks for your help. Do you need anyone to beta test the SDK and 1.1? I'm sure you get asked that a lot, but i can invest quite a bit of time into creating a control module for VRi.

Many thanks for all of your hard work

Pete

Captains,
The 757 manual is updated.
Now it includes SDK and the upcoming 1.1 features description.

Available via the 757 Sim Ops as usual: https://captainsim.net/products/y757/sops/

Added JPG files to the Manuals folder, please redownload it. We are sorry for the inconvenience.

Same concept but different IDs obviously.
For the 737 try the numbers from the 737 manual. They should match the code.

The 737 just needs a SDK. On the list.

Unfortunately we cannot debug third party developments. We've provided all the IDs and the general structure. The rest is upon your programmer's experience/luck.

Can anybody help on how to use the SDK and the LVARS ?
Any tutorial? Thanks

The SDK, that is included with the 757 III manuals (CS757CAPTAINIII_MANUAL_PART6_06.pdf), explains how to do what you want to do.

Hi all,

I just joined the forum because I am looking into purchasing the CS 757 to replace my 767 from another, unnamed company  . I have a full fixed base simulator with all actual 757 gauges and panels. I am currently interfacing all of this real hardware using the other SDK and a combination of Arduino and Cockpit Concept ARINC 429 cards.

I have some questions about the SDK that is available for the CS 757. First of all, let me say that the product looks simply spectacular. The attention to detail on things like the fonts on the CRT screens is second to none. And coming from that 767, you can understand what a huge improvement something like the fonts could be.

So here's my first question... I have a real 757 MCP. I have been looking over the CS 757 SDK and I can't seem to tell for sure whether or not it will allow me to WRITE a numeric value from the digits on the real MCP to a value in the CS 757 MCP. This includes the IAS/MACH, HDG, V/S, and ALT windows. Can someone please confirm whether or not values can be written from my panel to the software? I'll be clear in saying that I know how to convert the data coming out of the real MCP into data flight sim can understand (I have done it with the 767 already). I just need to know if the CS 757 SDK gives me the capability to write those values to it.

By the same token, can it go the other way? Does the SDK give me the capability to read the value of the digits on the MCP? This would be necessary for situations like the LOC capture when the heading value changes automatically to the runway heading, I need to know if I can READ that value from the software and then convert it to code the real MCP understands. Again, my question is not how do I convert the value to a code the MCP understands, just whether or not I can read that value through the SDK.

Wow, that was long winded, but I wanted to make sure I was clear in asking my questions. Any help would be greatly appreciated.

Thank you,
Matt

Thank you for your reply. With all due respect, I was not talking about using random numbers to overwrite the values on the MCP.

I am talking about using a REAL MCP to set the values on the software MCP. Say that I want to set an altitude of 25,000 on the MCP. I would turn my real MCP to show 25,000 but somehow that value needs to be written to the sim software so that it will set the altitude value in the software MCP to 25,000. If I am not supposed to write "random" numbers to the software, how exactly is one supposed to take the value set on a real MCP and set that in the sim?

Other SDK's that I have seen (including the one for the LVLD767) have variables that are read, writable, or both read/write. The MCP values are an example of a read/write variable because they need to be modified by both the software but also by any hardware. I am confused by the second part of your response saying that the hardware being a slave to the software. At some point, the software also needs to listen to the hardware in order to set the MCP values.

Thank you for your insights.

Matt

I said "to synchronize" not "to slave".

I can't help but what I can tell you is that there is no TOGA button on the 757....There are Go Around Paddles on the Throttle Quadrant but in the real world we run the Throttles to somewhere around 40% N1/ 1.02 EPR and then Engage the EPR/N1 button on the MCP....@ 1000ft AGL you select CLB on the thrust panel in front of the FO...in Europe or Noise Abatement Departures you select CLB at 1500 and begin Flap Retraction at 3k AGL

Hello everybody!

I'm using the L:Vars to interface real 757/767 hardware which works quite nicely. Currently I'm working on the altimeter and I want to set the altimeter/baro value directly instead of using a knob (rotary) action. Is this possible? I tried sending absolute values to both hPa and inHg variables, as well as to the knob L:Var without success.

Best regards,

Chris

Hi,

For the 7 segment displays i would use the IND's from the CS757 SDK. But how should I use them, interprete them? For example If i would to assign the 7-segment displays in my MCP regarding the IAS, I have to use the G03_001_IND. But where can I find the parameters of this VAR?

Kind regards,
Kees Schroijen

From the SDK:

FOR KNOBS ( _KNO)

1. Convert the element's name into an ID number.
2. Add the - (minus) for counterclockwise rotation.

For example:

(L:klid) = 1702003 - clockwise rotation.
(L:klid) = -1702003 - counterclockwise rotation.

So would the above from the SDK mean L:1702003 is clockwise rotation, and L:-1702003 is counterclockwise rotation?

If so, could this mean you need to use L:1703002 for clockwise rotation, and L:-1703002 for counterclockwise rotation (or something like that).

Note. I have no way of testing to know if this is correct, or not.

Hi All, making an B757 MCP, using the CW757 and Mobiflight software. I have the CW757 SDK, but i am having a problem interpreting it as am a newbie at this.

The Lvar for the Airspeed Display is G03_001_IND

How do i use this info to display the data on the 7-Segment -  Mobiflight uses offsets / the L:var has to be written to a free fsuipc offset and used thereafter

Is there any other software i can use that will be supported by CW757 or incase there is any script / technique i can use to display the data, please do share. 

Woud there be any guide or post that deals with using the SDK for home cockpit building on the forum ? 

Regards
AJ

Has anyone managed to get the KLID LVAR working properly? I've tried it for several different buttons, via FSUIPC offsets as well as Lua, with no effect.



Cheers

Luke
