Offset for opencockpit SIOC

[Alhard Horstmann]

Hi , I found in the Opencockpit SIOC script "FMC_PMagenta.txt"  the line "Var 3000, Link FSUIPC_INOUT, name offsetk, Offset $5428, Length 2 // CDU Functions "

Q: what is Offset $5428  ??

From the FSUIPC7 Offset status document - 3584 bytes starting at offset 0x5200:

Quote

Reserved:   5200-527F = Ferry van Aesch (Asst CEO British Airways Virtual)   5280- 52FF: Andrew McLean: Aerosoft Hardware   5300-53FF: Mark Hastings B777 Systems Simulator   5400-5FFF: Enrico's Project Magenta

 

i.e. Offset 0x5428 is in an offset area that has been allocated to Project Magenta, and you need to look at the PM documentation or ask them what that offset is used for.

thanks John. I will look in the PM documentation.

Again a question for Offsets: in my Opencockpit script "xpder_2enc.txt" ther is a line  "Var 0133, Link FSUIPC_OUT, Offset $7b93, Length 4 // IDT button for Squawkbox "

So where can I find info about Offset $7b93  ??

Again, all information on offsets is in the FSUIPC7 Offset Status document - why don't you look at that?

I provide extensive documentation so that I do not have to spen all day responding to such questions. Please ALWAYS consult the documentation (as well as checking these forums) before posting questions.

Hi John, I am so sorry and I dont want to bother you, sorry.

I looked in all existing documentation and of course in all FSUIPC docs ( as I did in the past 10 years). But my text search for $7b93 was not successful.

So  I learned now to search in the reserved section for code ranges.

like this Reserved: 7B80-7BFF = Squawkbox 3 (Joel DeYoung).  This range includes 7B93 !

Again , sorry for asking again.

Now I have to find a doc of Joel DeYoung  😎

All offsets in the documentation start with 0x and not $. But also only the starting offset is documented (together with the size), so rather than searching for a specific offset, just scroll down to you find the entry that documents the range for the offset you are interested in.

Yes - almost all the offsets that have been allocated to 3rd party software use was done many years ago, before my time, and I have no idea what these offsets are used for in most cases!

Cheers,

John
