🕒 Time and EEPROM Management Library

This library provides easy-to-use time management features and persistent storage using EEPROM. It contains two main classes:

• __zaman Handles time tracking and EEPROM-based calendar settings
• __epr Provides low-level EEPROM read/write operations

Includes convenient macros for consistent and formatted time string output.

📌 Features

---

• Time tracking and calendar synchronization using EEPROM
• 8-bit and 16-bit EEPROM read/write functions
• Formatted time string generation
• Persistent time storage across device resets

---

zaman CLASS FUNCTIONS

---

void setup(uint16_t bellek_baslangic = WTQ) → Initializes EEPROM and loads saved time data if available. → Takes an optional starting address (default: WTQ).

void millis_saat(uint16_t c = g_ms) → Updates time using the millis() function. → The optional parameter 'c' sets the update interval (default: g_ms = 50ms).

void eprden_oku(uint16_t basla = WTQ) → Reads time values from EEPROM starting at the given address.

void eprye_kaydet(uint16_t basla = WTQ) → Writes current time values to EEPROM for persistence after reset.

---

TIME VARIABLES

---

sn → Seconds (0–59)
dk → Minutes (0–59)
saat → Hours (0–23)
gun → Day of the month (1–31)
ay → Month (1–12)
hafta_gun → Day of the week (0 = Sunday, 6 = Saturday)
yil → Year (e.g., 2025)

---

epr CLASS FUNCTIONS

---

void yaz8(int adres, uint8_t veri) → Writes an 8-bit (1 byte) value to the specified EEPROM address.

uint8_t oku8(int adres) → Reads an 8-bit (1 byte) value from the specified EEPROM address.

void yaz16(int adres, uint16_t veri) → Writes a 16-bit (2 byte) value to EEPROM using two consecutive addresses.

uint16_t oku16(int adres) → Reads a 16-bit value from EEPROM by combining two 8-bit reads.

---

MACROS
