Thanks AJISH ALFRED for reply
I use in main
DisplayTimeToSeg(Get_DS1307_RTC_Time());
DisplayDateOnSeg(Get_DS1307_RTC_Date());
this take 130 ms
i understand from your reply that i make loop display the date and time and get the Time and date from DS1307 every 1 sec once so my question is that this 130 ms when i fetch the new time and date the 7 segment did not effect by this time
Thanks again
