i think you shold try this:
#define __16f877a
#include "pic/pic16f877a.h"
/* Setup chip configuration */
typedef unsigned int config;
config at 0x2007 __CONFIG = _CP_OFF &
_WDT_OFF &
_BODEN_OFF &
_PWRTE_OFF &
_LVP_OFF &
_XT_OSC;
//delay
void delay(unsigned int a)
{
volatile unsigned int i, j, k;
for(i = 0; i<a; i++)
for(j = 0; j < 10; j++)
for(k = 0; k < 255; k++);
}
//main
void main(void) {
TRISD = 0x00;
while(1) { /* Loop forever */
//LED1-LED7
PORTD = 0x3F; delay(1000);
PORTD = 0x00; delay(1000);
PORTD = 0x3F;
}
}
