Hello (and thanks in advance).
I'm having trouble when compiling an application. I'm using interrupts
to control a timer which changes a clock so it works as a countdown.
The problem arises when assembling the application, I get the
following error:
# sdcc -mpic14 -p16f877 --nooverlay
-I/usr/local/share/sdcc/include/pic/ -I/usr/local/share/sdcc/include/
-c temete1.c
temete1.c:62: warning 85: in function PaintClockTest unreferenced
function argument : 'x'
temete1.c:62: warning 85: in function PaintClockTest unreferenced
function argument : 'y'
temete1.asm:499:Error [115] Duplicate label or redefining symbol that
cannot be redefined. (_$_000021)
make: *** [all] Error 1
I have managed to guess that the error happens in line 218:
if (T0IF)
which is line 5 in the following code. I think this is needed to check
if the right interrupt has been triggered, but what's wrong with it
anyways?
The code that fails is as follows (extracted from attached file temete1.c):
static void Intr(void) __interrupt 0
{
BYTE result;
if (T0IF)
{
result = CountDecrement();
if (!result)
{
result = TimeDecrement();
if (!result)
{
// The treatment has ended.
T0IE = 0; // Disable the countdown;
}
else
{
PrintTime();
}
}
}
T0IF = 0;
}
