Use an older PC to drive the LCD with a CDU/FMC software running on it

is the latter really an already established mechanism, I was

No it wasn't an instantaneous idea.
yes, it was (at least on my side) - don't forget, that it
was me who initially brought that idea up in this thread,
regardless of the obvious fact that you've already realized
the whole thing :-)
But I am really amazed, that it's already implemented exactly
that way :-)
I have a prototype CDU "panel" (made from paper, overhead transparencies
and transparent contact paper).
http://cockpit.varxec.net/panels/img/cdu_panel1.jpg
in what graphics format did you design that panel ?
I think Harald might be able to use a good template as
a basis for a first skin.
So, if you got that panel in some common graphics format available-
preferably most of it as a vector image, one could easily use
such an image as a template for a skin based CDU and would already
have a usable basis for the rest of it.
So, one of the first steps would be to load such a vector
image, display it in a window and assign functions to
clickable regions.
Then another part of the whole panel would need to be defined as
a screen region that can be updated.
Check out X11GC, a x11-based glass cockpit software I'm working on.
Thats whats gonna drive my CDU. But for the logic behind it, the FMC,
it'd be nice to have a standalone program... :)
yes, I see - looks indeed quite promising !
do you have any materials about FMCs/CDUs ?
I sent already an eMail to Harald offering to
exchange the stuff that I've got here.
So, maybe you've also got anything that Harald might
find useful ?
the X11GC page:
http://cockpit.varxec.net/software/x11gc.html
so, then you are feeding FlightGear data to an application that then
uses a xserver and then connect that to a client ?
Well, Nasal doesn't fit too well in my "standalone" concept. I already
have a scripting language integrated into my X11GC/PHCC* programs (They
share some classes, and can be built into one binary).
I use LUA, an embedded scripting language.
http://www.lua.org/
Easy to learn and easy to integrate into your own programs :-)
yes, I know lua - and have used it for some smaller things myself,
and actually I am again looking into it ...but on the other hand
FlightGear has already Nasal and speaking of my personal ideas,
it would be really a bit pointless to use lua instead of Nasal
simply because Nasal is not supposed to "become everbody's swiss
army knife".
On the other hand, a Nasal based implementation of the logics could
still work - either using the Nasal library itself or simply using
the network for data exchange.
