timer1 using for count

[hamza bilgen]

when the ext1=1 , timer 1 must run and when timer1 is full ,rb7 is on. but as soon as the ext1=1 rb7 is on why ? i dont understand. because timer must wait 12.5 ms but it dont wait.
what is wrong?




#int_timer1
void tmr1_isr()

{
output_bit( PIN_B7, 1);
disable_interrupts(INT_TIMER1);
}

#int_ext1
void rb1_isr()
{
set_timer1(45000);
enable_interrupts(INT_TIMER1);
}


these are main's code samples about timer1

setup_timer_1 ( T1_INTERNAL | T1_DIV_BY_1|T1_DISABLED );
enable_interrupts(INT_TIMER1);
enable_interrupts(global);
enable_interrupts(int_ext);
enable_interrupts(int_ext1);

set_tris_d(0x00);
set_tris_b(0b00000011);

I don't see that Timer1 is enabled. Here, you have disabled it:

setup_timer_1 ( T1_INTERNAL | T1_DIV_BY_1 | T1_DISABLED );

sorry i write wrong
i am correcting
#int_timer1
void tmr1_isr()

{
output_bit( PIN_B7, 1);
disable_interrupts(INT_TIMER1);
}

#int_ext1
void rb1_isr()
{
set_timer1(45000);
enable_interrupts(INT_TIMER1);
}
