Dear All,
I wrote a program to read DS1307 and put the result on the LCD using PIC16f877a via I2C protocol. It is working properly and I connected backup battery also. only problem is when I removed the main power the RTC does not update, and it is counting only five seconds when remove the main power
Please Advice
