I think you have a different definition of "embedded" from me
(admittedly it's a broad term). C is still in wide use in the industry I
work in (which produces small, hard real time systems). This is unlikely
to change in the near future: C++ is perceived as being slow and unsafe.
There's the feeling that you never quite know what it's going to do.  By
contrast, C compilers are pretty efficient and what they'll end up
producing is more or less in line with what you'd expect from looking at
the code. C itself can be unsafe, of course, but by using restricted
subsets of the language you can help with this somewhat (banning dynamic
allocation is common, for example).

I don't think these systems are simple. If they were, writing them would
be a lot easier.

ObFourYorkshiremen: You had an OS? You were lucky! In my day we had some
interrupts and timers, and we liked it! (Actually, my current project
does have an OS: such luxury :-)
