PIC16F877A Development board

[vick5821]

Hey guys, recently I tried to build a development board for PIC...but I failed .

The LED doesnt blink as what the code was.

Any suggestion or maybe my circuit error ?

Thanks

CODE: SELECT_ALL_CODE

#include <pic.h>

__CONFIG ( 0x3F32 );

#define LED RB5

void init(void);
void delay(unsigned long data);

void main(void)
{
init();
LED=1;
delay(10000);
LED=0;
delay(10000);
LED=1;
}

void init()
{
TRISA=0b00000000;
TRISB=0b00000000;
TRISC=0b00000000;
TRISD=0b00000000;
TRISE=0b00000000;

}

void delay(unsigned long data) //delay function, the delay time
{
for( ;data>0;data-=1); //depend on the given value
}

Your program only blink once. you have to enclose the LED on/off inside a "While(1)" loop.

CODE: SELECT_ALL_CODE

void main(void)
{
init();
while(1)
{
LED=1;
delay(10000);
LED=0;
delay(10000);
// LED=1;
}
}
