Interfacing RTC & serial EEPROM using i2c bus, with ATmega128 uC

Blog / Ibrar Ayyub

Hi friends, here is my experiment with i2c bus for interfacing serial EEPROM (24C256) and RTC (DS1307) using AVR microcontroller ATmega128. The circuit is also provided with an RS232 port for connecting with PC to send commands for reading/writing EEPROM or setting date/time in RTC (Click on images to enlarge them). Communication with PC is
