Hello,
has anybody expierienced with the Realview Compiler (ARM) and C++ interrupt programming? How can I call an non static method as a interrupt handler? I use ATMEL AT91SAM7 controllers. It's not easy if one has just started to learn C++ at all ... (the reviews I found haven't helped me much).
Interrupt programming really has nothing to do with C++ - actually, C++ is not a factor in it whatsoever. use standard C or assembly for that, and refer to your compiler's data sheet to see how. by the way, I hope you are aware of the intricacies involved in using C++, especially on microcontrollers...?

Andy, I read the article. My personal opinion is that the risks that are introduced into software by using C++ are far greater than the mild benefits of stripped embedded C++. Yes, sometimes I'm DIEING to able to inherit, but for me, in comes down to the following: writing correct C++ code is far more challenging that writing C code. performance might be more of less the same (given a good compiler and some size trade-offs) but still - I would not use it for really low-level software.

Thank you for the link, but I'll stick to C :-) There is actually a lot to loose: C++ is much harder to learn and use. And the only real-world example in the article is not convincing at all...
