Hello Gents,
I am having problem communicating between main.c and another
file/module, ui.c to name it.
In main.c I set a flag from a timer ISR, every 100ms.
In ui.c I am watching for that flag, but unfortunately it always
reads zero :-/ However if I watch for the flag in main() then it works
fine.
I am watching the flag in ui.c, so I declared it in ui.h, then ui.h
gets included in main.c so I can set the flag from there.
Well that was my reasoning, but doesn't quite work sadly !
I must be doing something wrong obviously, just would love to learn what
it is ! ;-)
Regards,
--
Vince, a bit stuck and wondering again...
ui.h
-----------
static volatile uint8_t flag;
ui.c
----------------
if( flag )
{
flag = 0;
/* Do some stuff */
}
main.c
--------
#include "ui.h"
ISR (TIMER0_COMP_vect)
{
flag = 1;
}
main() {}
