Code:

/* port_blink.c
By Tarilayefa Edward

Date: 15/11/2016.
A simple port blinking code that flashes port a and b on/off
at the rate of t1 milliseconds.
Compiler: PCWHD Compiler v5.008
PIC16F88 used.

#include <16F88.h> //include pic16f88 header file
void main(void) {

//#byte OSCCON = 0x60 //4MHz 0scillator
#byte OSCCON = OSC_4MHZ //4MHz 0scillator
//#byte OSCCON = 0b01101000 //4MHz 0scillator
//#Fuses NOWDT,WDT,PUT,NOPUT,LP,XT,HS,EC_IO,INTRC_IO,INTRC,RC_IO,RC
#Fuses INTRC_IO //internal osc used with a6, a7 as digital pins
#use delay(clock=4000000) //4mhZ CLOCK SPEED
setup_adc(ADC_OFF);

set_tris_a( 0x00 ); //SET port a to output
OUTPUT_a(0x00); //turn off porta
set_tris_b( 0x00 ); //SET port b to output
OUTPUT_b(0x00); //turn off portB

int16 t1; //declare t1 as 16bit variable (0 to 65535)

//OUTPUT_HIGH(PIN_B0); //turn on portb.0
