Hi All -
I am using DS1307 RTC to make a digital clock. In order to run it I am using 32.768kHz crystal and displaying time on LCD. Everything is working fine. I am able to set the time and date. But only problem is that clock is not ticking.
I simulate the circuit in Proteus 7.. Where it works perfectly.
I am using cylindrical crystal and not using any capacitors across it.
Also, I used P89C51RD2 as uC in the circuit.
Please let me know how can I fix this proble??
Do I need to put capacitors across crystal ??
If yes, what should be the value of those capacitors??
Thanks in advance.
