The way I use this works. Code is for the uart interrupts:
main.c:
extern _RC_handler;
extern _TX_handler;
DEF_INTHIGH(high_int)
DEF_HANDLER(SIG_RC, _RC_handler)
DEF_HANDLER(SIG_TX, _TX_handler)
END_
Hi,
Thanks for the clarification, I understand the problem.
writing "extern isr_name;" is perfectly fine for me, just had to know it!
Would that make its way into the documentation as a tip?
could this be implemented as a #pragma symbol USED or another declarator
attribute one day or another?

Hi,
C is a bit lax with types -- if there is none given, it often assumes int,
as in ''extern portb_isr'', which is (correctly) interpreted as
''extern int portb_isr;''.

Hi,
thanks, this weird "extern" statement did the trick. I did not know this
syntax.
But that's strange:
For a SIGHANDLER that is defined in the SAME file, I have to forward declare
it using: SIGHANDLER(portb_isr); ; extern portb_isr fails with:
main.c:162: error 98: conflict with previous defin

hi,
i'm playing with interrupts in pic18.
in main.c I have:
#include
SIGHANDLER(i2c_slave_isr); //forward declaration, implementation is
elsewhere
DEF_INTHIGH(high_int)
DEF_HANDLER(SIG_SSP, i2c_slave_isr);
END_DEF
