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.

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
