Using the LCD

The library provides an LCDGraphics class to deal with the LCD. But in this stage, the LCDGraphics class haven't implemented completely. This page is only for testing the features.

LCD lcd = new LCD(); //Creates an ev3dev LCD instance.

LCDGraphics g = new LCDGraphics(lcd); //Creates the LCDGraphics class

//The LCD only supports BLACK and WHITE. Specifying other colors
//will result an exception

//g.setColor(Color.WHITE); //Sets color to Color.WHITE
//g.setWhiteColor(); //Alternative
//g.setColor(Color.BLACK); //Sets color to Color.BLACK
g.setBlackColor(); //Alternative

//The library currently implements the drawLine() and fillRect() method
g.drawLine(0, 0, 100, 30); //Draws a line from (0,0) to (100,30)
g.fillRect(50, 50, 25, 25); //Draws a 25x25 rectangle at (50,50)

g.flush(); //Applies the graphics to the LCD
