 * @file main.c
 * @brief 8x8 R Click example
 *
 * # Description
 * This demo example shows a drawing of Image, new create string and character on the screen.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring Clicks and log objects.
 * Settings the Click in the default configuration.
 * 
 * ## Application Task  
 * Shows one byte, then scrolls the string and image, every 1 sec.
