My background, embedded (mcu, pc, unix, other), realtime. Safety critical. I introduced a previous employer to STL. I don't do that anymore.

Some Flame content

Is C++ suitable for embedded systems?

Meh. C++ is a pain to write and a pain to maintain. C+ is sort-of okay ( don't use some features)

C++ in Microcontrollers? RTOSes? Toasters? Embedded PCs?

Again I say Meh. C+ is not too bad, but ADA is less painful (and that's really saying something) . If you're lucky like me, you get to do embedded Java. Checked array access and no pointer arithmetic makes for very reliable code.

Is OOP useful on microcontrollers?

Sure is. The UART is an object..... The DMAC is an object...

Object State machines are very easy.

Does C++ remove the programmer too far from the hardware to be efficient?

Unless it's a PDP-11, C ain't your CPU. C++ was originally a preprocessor ontop of C so Bjarne Strotrup would stop getting laughed at for having slow Simula simulations while at AT&T. C++ ain't your CPU.

Go get an MCU that runs java bytecodes. Program in Java. Laugh at the C guys.

Should Arduino's C++ (with no dynamic memory management, templates, exceptions) be considered as "real C++"?

Nope. just like all the bastardised C compilers out there for MCU's.

Forth, Embedded Java or Embedded ADA are standardised(ish); all else is sorrow.

Checked array access and no pointer arithmetic makes for very reliable code. Garbage collectors in embedded Java are not highest priority, and there is scoped memory and object reuse, so well designed code can run forever without a GC.
