| Settings of timer1 interrupt |

Hello everyone again. I have a problem with Timer1 interrupts in my code. I want to generate pulses that drive my stepper motor. My motor is gonna work 8 sec (3200 pulses) and stop 4 sec continuously by using Timer1 but i couldn't handle this. Can you help me to set this Timer1 ?
| Code: | #device PIC16F877A
#include <16f877a.h>
#fuses xt,nowdt,noprotect, nobrownout, nolvp, noput, nowrt, nocpd
#use delay (clock=4000000)
#use fast_io(b)
#use rs232 (baud=9600,xmit=pin_C6, rcv=pin_C7, parity=N, stop=1, Bits=8)
unsigned int16 counter = 0, interrupt=0; //
char operation;
//#priority rda, timer1
void right_direction_commands()
{
output_high(pin_b3);// motor aktif,motor enable pin
delay_ms(100);
output_high(pin_b1);// motor yönü belirlendi, motor direction pin
sayac=3200;
printf("\r\n right start\r\n");
}
void left_direction_commands()
{
output_high(pin_b3);
delay_ms(100);
output_low(pin_b1);
sayac=3200;
printf("left start \n\r");
}
void stop_commands()
{
output_low(pin_b3);
sayac=0;
printf("motor stop \n\r");
}
#int_rda
void serihaberlesme_kesmesi ()
{
operation=getch();/
putc(ioperation);
output_toggle(pin_b0);
if(operation=='r')
{
right_direction_commands();
}
if(operation=='l')
{
left_direction_commands();
}
if(operation=='s')
{
stop_commands()
}
}
#int_timer1
void timer1_interrupts()
{
set_timer1(64923);
interrupt++;
output_high(pin_b2);
delay_us(20);
output_low(pin_b2);
if(interrupt==counter)
{
interrupt=0;
}
}
void main()
{
delay_ms(300);
setup_psp(PSP_DISABLED);
setup_timer_2 (T2_DISABLED,0,1);
setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_OFF);
setup_CCP1(CCP_OFF);
setup_CCP2(CCP_OFF);
set_tris_b(0x00);
output_b(0x00);
setup_timer_1(T1_INTERNAL|T1_DIV_BY_4); //262 ms overflow //65,5 ms overflow
set_timer1(64923);
enable_interrupts(GLOBAL);
enable_interrupts(INT_rda);
enable_interrupts(INT_timer1);
printf("\n\r System initializing....\n\r");
printf("\n\r bir islem seciniz...\n\r");
while(TRUE)
{
}
}
