Hi,
> has anyone succesfully used C++ on PSoC?
I answered I have.
But please note that C++ is not supported by PSoC Creator, so what we are doing is hacking
and not guaranteed nor recommended.
And I also can not guarantee nor recommend it (at least for the time being).
Having written above, you know, I tried my hack using CY8CKIT-059 😉

Tera Term Log
So the good news is at least my c++ program could be compiled and my cat can walk a little.
The bad news is that there is no one who will guarantee nor support for further exploration.
