public class LCDOutputStream

extends java.io.OutputStream

A LCD output stream is an output stream for writing data to a LCD Display. This class can be used for direct writting to the LCD display on the TINI developers station. It has been tested with LCDs that use the Samsung KS0066U and KS0070B segment drivers. Using this stream, you can create a PrintStream and do println()s to the display. Each println will show up as the next available line on the display.
