Hi,
Here's one solution I have used: I looked how SIGNAL and INTERRUPT are defined
in avr/signal.h and changed the attribute signal or interrupt to naked
#define MYISR(signame) \
void signame (void) __attribute__ ((naked)); \
void signame (void)
attribute naked is _really_ naked so that no prologue nor epilogue is added at
all. Therefore you need to add your prologue and epilogue by hand in every
ISR you have:
MYISR(signame) {
MyISRPrologue();
/* ISR code */
MyISREpilogue();
}
MyISREpilogue() must have a reti instruction as the last instruction.
I hope this helps.
