 * 
 * # Description
 * This application writes in memory and reads from memory.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver, resets device and tests communication.
 * 
 * ## Application Task  
 * Clears the memory sector, writes "MikroE" to device memory
 * and then reads it and sends it to log every 2 sec.
