 * @brief EEPROM 6 Click Example.
 *
 * # Description
 * This example demonstrates the use of EEPROM6 click board by writing 
 * string to a memory at some specific location and then reading it back.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * This example shows capabilities of EEPROM 6 Click board by writting a string 
 * into memory location from a specific address, and then reading it back every 5 seconds.
