I have made my PCB and the RTC is only 55 sec less ever minutes(60 sec).
May be there is an issue with the PCB track.
Is there a way to adjust the clock digitally by adjusting any register
Thanks for your time

@ microt -
Something wrong with your code, battery, or capacitors.
Cheating code is not good way in this case.
Hi
I tried this as per the LPC1788 manual.
It is not taking effect.
Can GPI look at this. I want to tune the RTC
Register RTC_ENA = new Register(0x40024008); //RTC Cal Enable
RTC_ENA.Value = 0<<4 | 1<<0;
Register RTC_CAL = new Register(0x40024040); //RTC Cal Value: Slow 1 sec every 30 sec
RTC_CAL.Value = 1<<17 | 30;
@ microt - Do you have datasheet for the crystal you have used and the capacitors?
