    lcd.c:
          LCD-driver ARM-board v5

    pin-info:
           PE2  - DB4   --->> PE3
           PE4  - DB5
           PE5  - DB6
           PE6  - DB7
           PC13 - E:  start data
           PC15 - RS: register-select
           PC14 - RW: read/write

    opmerkingen:
                -Alle instructies voor het display staan achterstevoren! (maakt
                 de code wat eenvoudiger)
                -Zorg ervoor dat de delay-code ook wordt meegecompileerd, anders
                 gaat het hier mis...
                -Deze code is gebaseerd op
                 "LCD routines for OLIMEX LPC-MT-2106,16x2 Character LCD 1602K,
                  4-bit mode operation",
