Now, I realized that my g++ ignores the "#pragma interrupt" directive. I.e.: #pragma interrupt extern "C" void isrCPP { // }; The compiler accepts this code, but it does not save or restore the registers and does not add a "Return-from-Interruption" op-code (rete in the asm). Is it a known bug? I am missing something? Also, I am interested in a good OO mechanism to dispatch the interrupts. If you know a good reference or you want to discuss about it please tell me.
