I think this is due to it not being called. I ran into a similar problem where
interrupt handlers weren't being included in the app.c file, and what i realized was:
1. Functions that aren't called aren't included in the app.c file
2. Interrupt handlers are never explicity called
If you look in the tinyos-1.x/tos/platform/avrmote/avrhardware.h you'll see the
following lines:
#define TOSH_SIGNAL(signame) \
void signame() __attribute__ ((signal, spontaneous, C))
#define TOSH_INTERRUPT(signame) \
void signame() __attribute__ ((interrupt, spontaneous, C))
It looks like you are trying to redefine the attributes, so you might try modifying
your code to look like this:
TOSH_SIGNAL(SIG_OVERFLOW1) {
high16=++;
}
(not sure if this should be TOSH_INTERRUPT or TOSH_SIGNAL, I don't know the difference
between them.)
Hope this helps!
