Ok, you're free to do what you want, but I feel I must make a comment.

C++ uses more resources (RAM and flash) than the same thing done in C code.
C++  tends to need far more dynamic memory allocation/freeing. Something that 
is typically not very well handled on small embedded systems.
C++ hides detail making it harder to debug on an embedded platform.

In short, C++ and small embedded systems don't mix very well. In over 20 
years of embedded programming I have never found a compelling need for C++ on 
smaller systems.

There is nothing theoretical preventing the use of C++ on ARM7 though. It 
will all be stuff to do with your compiler settings, linking, and making sure 
you provide all the runtime stuff that C++ needs.
