		<description><![CDATA[The reason why I&#8217;m using a LCD display is because it allow me to display many characters and it doesn&#8217;t need to be &#8220;refreshed&#8221; as 7-segment Led displays. Also, the interface requieres less I/O pins. For this project I used a 16&#215;1 LCD Display with 4-bits interface. 22pF capacitors keeps the clock accurate. Read the [...]]]></description>
