| Does get_timer1() conflict with Timer1 Interrupt |

Hi,
I found out that my processor has two timers, TIMER0 and TIMER1, but I can use only Timer1 since TOCKI is used for GPIO function.
So can I disable INT_TIMER1 before it needs to check timeout wtih set_timer1(0) and get_timer1() and enable INT_TIMER1 back after checking timeout event is finished?
| Code: |
#include <16F689.h>
#include <stdio.h>
#include <stdlib.h>
#use delay(clock=3686400, crystal)
#use rs232(baud=115200, xmit=PIN_B7, rcv=PIN_B5)
#fuses XT, NOWDT, PUT, MCLR, NOPROTECT, NOCPD, NOBROWNOUT, NOIESO, NOFCMEN
unsigned int16 x;
#INT_TIMER1
void timer1_isr(void)
{
set_timer1(0x1F00); //500ms
EVENT_1();
}
void main()
{
setup_timer_1( T1_INTERNAL | T1_DIV_BY_8);
enable_interrupts(INT_TIMER1);
enable_interrupts(global);
while(1)
{
disable_interrupts(INT_TIMER1);
set_timer1(0);
EVENT_2();
x = get_timer1();
enable_interrupts(INT_TIMER1);
}
}

Thanks. |

What happened to putting Timer1 questions all in one thread, rather than
a bunch of scattered posts ? |

| Since my questions are different about Timer1, I do not want to confuse people. I am sorry about this. |
