hi sir, i am new to this rtc ds1307 and want to know dat according to its datasheet it is battery backed....does that mean that you need not initialize it when you use it for the first time?????
and if i want to simulate it on proteus software it shows correct date and time automatically without writing it for the first time.....
i m unable to understand all this plzzz help me out....and i m sorry if i irritated you...
The whole point of running code in a simulator is so that you can easily step through it and see exactly what is happening internally.
Doing that, you should be able to see exactly where it writes to the LCD, and what it attempts to write...
