[pitufos]

Hi, look this example....


#include <16C84.H>

#fuses HS,NOWDT,NOPROTECT

#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_A3, rcv=PIN_A2)


#define INTS_PER_SECOND 76 // (20000000/(4*256*256))

byte seconds; // A running seconds counter
byte int_count; // Number of interrupts left before a
// second has elapsed

#int_rtcc // This function is called every time
clock_isr() { // the RTCC (timer0) overflows (255->0).
// For this program this is apx 76 times
if(--int_count==0) { // per second.
++seconds;
int_count=INTS_PER_SECOND;
}

}


main() {

byte start;

int_count=INTS_PER_SECOND;
set_rtcc(0);
setup_counters( RTCC_INTERNAL, RTCC_DIV_256);
enable_interrupts(RTCC_ZERO);
enable_interrupts(GLOBAL);

do {

printf("Press any key to begin.\n\r");
getc();
start=seconds;
printf("Press any key to stop.\n\r");
getc();
printf("%u seconds.\n\r",seconds-start);

} while (TRUE);

}

when i compile program, haven this error ....
the variable RTCC_ZERO is not declared...
why ?


Thank's...
