is this correct?
Code: |
#include <16f877a.h>
#use delay (clock = 2000000)
#fuses hs,nprotect,nowdt,nolvp
void main ()
{
enable_interrupts(int_timer2);
enable_interrupts(GLOBAL);

It's not completely correct... if you don't have case sensitivity disabled, it's INT_TIMER2 and not int_timer2. And fo course that code fragment is incomplete. But you have the general idea, yes.
Did a new semester just start somewhere? |

what I'm trying to do is I'm using this PIC16f877a
and I'm using the ccs c compiler
-PIC will continuously toggle LED at PORT RB1, RB2 and RB3 and toggle buzzer ON and OFF in seq every 1 sec. When interrupt occur all LED will automatically turn OFF and only turn ON LED RB4. (interrupt is timer2).
And after 2sec all sequence function back as normal .
My problem is I don't know how to use the timer2 interrupt. Sorry guys. I'm newbie |

Obviously you're the same person as fariq23 here, because you have
the same exact requirements, LED, Buzzer, 2 seconds:
