Help interrupt : NEWBIE

[Guest]

Hi guys , i know it is probably simple , but i can't find why this simple code doesn't work

all i want a do with it , is to change the value set in timer1 using an analog input, varying the analog should change the speed of the blinking LED , i have been able to do it in 8 bits using Timer0 but not in 16 bit with timer1

Thanks for your help!!

here the code

#include <16F676.h>
#device adc=10
#fuses INTRC_IO,NOWDT,PUT,NOPROTECT,BROWNOUT,NOMCLR
#use delay(clock=4000000) // 4MHz clock

long atime=0;
long itime=0;
byte i;


#INT_TIMER1
void Timer1()
{

set_timer1(atime);
if (itime==512)
{
output_low(PIN_A5);
output_high(PIN_A4);
}
else
{
output_low(PIN_A5);
output_low(PIN_A4);
}
if (i==1)
{
output_high(PIN_A1);
output_low(PIN_A2);
i=0;
}
else
{
output_low(PIN_A1);
output_high(PIN_A2);
i=1;
}
}

void main()
{
set_tris_a(0xf1); //


setup_timer_1(T1_INTERNAL|T1_DIV_BY_8);
set_timer1(atime);
enable_interrupts(GLOBAL);
enable_interrupts(INT_TIMER1);

setup_adc_ports(sAN0);
setup_adc(ADC_CLOCK_DIV_16);

while(1==1)
{
set_adc_channel(0);
itime=read_adc();
delay_us(50);
atime=itime;



}
}

Sorry guys , don't waste your time on it !!!, everything is working OK , my loop is so long that i could not see the speed change of the leds !!!!
