/**
 * @file eeprom.h
 *
 * @brief Header file for configuration settings and EEPROM operations in the DE-Timer application.
 *
 * This file defines configuration settings for the DE-Timer project, including default values,
 * EEPROM structures, and functions for EEPROM operations. It also defines enums for different Battery Types.
 * Additionally, it includes functions for EEPROM handling such as storing, retrieving, and formatting configuration data.
