 * @brief EEPROM5 Click example
 *
 * # Description
 * This is an example that demonstrates the use of the EEPROM 5 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enables SPI, also write log.
 *
 * ## Application Task
 * In this example, we write and then read data from EEPROM memory.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs write on USB uart changes approximately for every 3 sec.
