Hi All,
Recently i have played the RTC DS1307 and works fine with continuous 5V supply.
However, when i try to connect the backup battery and cut the 5V supply for one day...and then give the 5V supply again...discovered that the clock has been slowed down....
what are the possible reasons for such problem??
Remark that i have shared the I2C pins with EEPROM. The crystal is just soldered beside DS1307...
Thanks in advanced..
