Sammel-Interrupt mit avr-gcc

**ogni42** · 24.02.2006, 10:40

Hier mit retten von r24. Jetzt sollte nichts mehr kaputt gehen:

Code:

#include <avr/interrupt.h>
#include <avr/signal.h>
#include <inttypes.h>

void foo( uint8_t whichISR )
{
	volatile uint8_t isr = whichISR;
}

void _VECTOR(1)( void )  __attribute__ ((naked));
void _VECTOR(1)( void )
{
 	__asm__ __volatile__ ("push r24" ::);
   foo(1);
 	__asm__ __volatile__ ("pop" ::);
    __asm__ __volatile__ ("reti" ::);
} 


void _VECTOR(2)( void )  __attribute__ ((naked));
void _VECTOR(2)( void )
{
 	__asm__ __volatile__ ("push r24" ::);
   foo(2);
 	__asm__ __volatile__ ("pop" ::);
    __asm__ __volatile__ ("reti" ::);
} 


void _VECTOR(3)( void )  __attribute__ ((naked));
void _VECTOR(3)( void )
{
 	__asm__ __volatile__ ("push r24" ::);
   foo(3);
 	__asm__ __volatile__ ("pop" ::);
    __asm__ __volatile__ ("reti" ::);
}
