Hi Vivek,
Your parts look OK for the microcontroller side of things. There is plenty of sample code around for using the display, and i2c code for the RTC and EEPROM is simple enough. If you pick the right compiler, it will have these functions built-in, so you can concentrate on the logic of the problem (...)

Hi,
In any case you have to set the external address of 24xx to match with the LS three bits of the address byte. I could not find from the data sheet if the five bit control code will change under some conditions, so I suggested you to select an address different from RTC's address, using the external address. So long as the device addresses ar
