/*   Project: Unit 10 - 7SEGS
        Code: unit_10_2_upDownCounter7segs.c

   Objective:   This program use interruptions and writes the value of incremented button
                on the 7-segment displayCrystal = 8MHz:)
                The example program below was compiled on the mikroC compiler (www.mikroe.com)
                and aims to write on displays Kit PICGenios Microgens Technology Center.
                Note: It does make use of the scanning technique (on-off-on cycle);
                      all the LEDs stay on for 1ms and we get the impression that
                      all the LEDs are on at the same time forever;

   Objective:   This is the Hello World for IOC - Interrupt-on-Change:D
                When user presses PORTD.RB4 the LED's at PORTD.RB0 will change for
                both rising and falling edge(press, hold and release to see effect)
                PORTD.RB1 is blinking by the polling tecnique.

   Objective:   In this project let's use INT0, INT1& INT2 INTERRUPTIONS, all together:
                By pressing PORTB.RB0(INT0) an LED(PORTD.RD4) will light up \o/
                By pressing PORTB.RB1(INT1) an LED(PORTD.RD5) will light up \o/
                By pressing PORTB.RB2(INT2) an LED(PORTD.RD6) will light up \o/
                All external interrupts (INT0, INT1 and INT2)
                can wakeup the processor from Idle or Sleep modes "/
