Here's a little program which link the LED ( sorry comments are write
in french because i am french :-) )
i think it can works on 16f84. I'm working now on it but i hav'ent
tested on 16f84. Its work fine on 16f690
#include <pic16f690.h>
/* clignotement d'une diode a une fréquence donnée */
typedef unsigned int word;
word at 0x2007 __CONFIG = (_INTRC_OSC_NOCLKOUT & _CP_OFF & _WDT_OFF &
_BOR_OFF & _PWRTE_ON & _MCLRE_OFF & _IESO_OFF & _FCMEN_OFF);
void attente(unsigned char k, unsigned char l) /* Routine de
temporisation */
{
unsigned char i,j;
for(i=0;i<=k;i++)
for(j=0;j<=l;j++);
}
void main()
{
TRISC = 0x00;/* postionnement de PORTC en sortie */
while(1)
{
PORTC = 0x01;
attente(50,50);
PORTC = 0x00;
attente(50,50);
}
}
