LED flasher
PostPosted: Mon Apr 19, 2004 11:12 pm     Reply with quote
Hi,

Anyone has a sample code snippet for a LED flasher... say it turns on for 500mS at the same time it flashes then turns-off for one sec. I plan to use a timer interrupt.

Thnx

Lazy??? How about doing some research yourself before asking a question here?

There have been numerous examples of this. Use the Search function!

Hello

Code:
#include <16f877.h>
#use delay(clock=4000000)
#fuses HS,NOWDT,PUT,NOLVP

signed long int t0_conta;

#int_timer0
void trata_t0 ()
{
   static boolean led;
   t0_conta -= 256;
   if (t0_conta<=0)
   {
      
      t0_conta += 2500;
      led = !led; 
      output_bit (pin_c2,led);
   }
}

main()
{
   t0_conta = 2500;

   setup_timer_0 ( RTCC_INTERNAL | RTCC_DIV_4 );

   enable_interrupts (global | int_timer0);
   while (true); // espera interrupção
