Write_address is for recording, bat is for reading.
Lets say there are 3 reading:
first reading:
Read RTC then write at eeprom at 0
second reading:
Read RTC then write at eeprom at 7
third reading:
Read RTC then write at eeprom at 14
....
Then a show is made by putting C.7 to 0
Bat reads at 0
then bat reads at 7
then reads at 14.
...
A write is made again it is written at Write_address = 21
...
I am only using the first three anyway.
This is not the problem, the seconds for the first three reading are the same !!!!
eXAMPLE:
If I take 8 readings at 5 seconds interval, My results are that the first 3 are have the same time ie: 02:04:11 , the following 3 are: 02:04:27. last two are 02:04:38
