 * # Description
 * This application draw image on the led matrics.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization default device configuration, sets LED mode, 
 * configuration ABM and display one character.
 * 
 * ## Application Task  
 * Clear display, display one by one leds, display one character,
 * display image and display text with scroll.
