Using the LCD: making a news ticker

In this tutorial we explain how text can be shown on the LCD of the Dwengo board and how to operate the backlight of this display. The first result of this tutorial is a program that shows "Dwengo Board" on the first line of the display and on the second line a slowly increasing number. As an extension we show how you can display a text that is longer than 16 characters on one line of the screen by using a news ticker effect (commonly used for displaying stocks).
