LED Blinking with PIC16F877A Starter Board Revision as of 15:38, 27 April 2016 by Sharana (Talk | contribs) (diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)

In this tutorial we will learn how to blink the LED's with PIC16F877 Starter Board. The Explore Starter PIC board has two on board LED's which are connected to PORT D0 and PORT D1.

Code

	#include <pic16f877a.h>
	void DELAY_ms(unsigned int ms_Count)
	{
	unsigned int i,j;
	for(i=0;i<ms_Count;i++)
	{
	for(j=0;j<1000;j++);
	}
	}
	int main()
	{
	/* Configure all the ports as Output */
	TRISA = 0x00;
	TRISB = 0x00;
	TRISC = 0x00;
	TRISD = 0x00;
	while(1)
	{
	PORTA = 0xff; /* Turn ON all the leds connected to Ports */
	PORTB = 0xff;
	PORTC = 0xff;
	PORTD = 0xff;
	DELAY_ms(100);
	PORTA = 0x00; /* Turn OFF all the leds connected to Ports */
	PORTB = 0x00;
	PORTC = 0x00;
	PORTD = 0x00;
	DELAY_ms(100);
	}
	return (0);
	}
