 * \brief Eeprom2 Click example
 * 
 * # Description
 * This application demonstrates the process of writing and
 * reading of data from EEPROM.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes EEPROM 2 driver.
 * 
 * ## Application Task  
 * Writing data to EEPROM and then reading that data and writing it via UART.
