I think C++ is a crappy language in the first place. If you want to use OOP, write Java programs. C++ does nothing to enforce OOP paradigms, as direct memory access is fully within your power to (ab)use.

If you have an MCU, you're talking about most likely less than 100kB of flash memory. You want to be programming in a language whose abstraction of memory is: when I declare a variable or an array, it gets memory, period; malloc (aka "new" keyword in C++) should be more or less banned from use in embedded software, except perhaps in rare occasions one call during program startup.

Hell, there are (frequently) times in embedded programming where C is not quite low-level enough, and you need to do things like allocate variables to registers, and write inline assembly to tighten up your interrupt service routines (ISRs). Keywords like "volatile" become pretty darn important to understand. You spend a lot of your time manipulating memory at the bit level, not the object level.

Why would you want to delude yourself into thinking that things are simpler than they in fact are?
