[avr-gcc-list] avr-g++ and interrupt vectors

[Nils Kristian Strom]

Hi! 

I am experimenting with C++ on the AVR, trying to implement a simple
class for a timer.  I ran into a problem when trying to declare the ISR
as part of the class. 

In plain old C, my ISR looks like this: 

SIGNAL( SIG_OVERFLOW1 ) 
{ 
        timer_count++; 
} 

In my C++ implementation what must I use ?

I would expect something like 

SIGNAL( SIG_OVERFLOW1 )  // <- Make vector jump to Timer::Interrupt
Timer::Interrupt() 
{ 
        count++; 
}

The main issue is that Timer::Interrupt() should be a private member
function of Timer.  If not, I could use the plain C alternative and make
Timer::count public, however, this is not what I want.


Regards,
  Nils
