Anyone wants to share an interesting/cool embedded Pascal project?

Agreed. That's /particularly/ the case when one follows through the code to read or change the state of a bit: Arduino (and others that I've looked at) try to make this general but the result is a sequence of complex function calls that the compiler can't optimise... the collective developers appear either unconcerned or unaware.
But unfortunately, no matter how we loathe them, some things we're stuck with :-(

Which is not necessarily a problem. ;)

So to what extent can interaction between FPC and C++ be promoted? The risk is that problems would cause vexation to both the FPC and embedded communities: and as a minor player FPC can't IMO afford to be vexatious.

cppclass doesn't handle all types yet (e.g. signed char), so declarations might fail because the wrong mangled name is generated, and there's no way to deal with operator overloads (if any) yet. So right now I'd advertise it as “experimental” at most.
