#157716 - How to design an hour meter using RTC and AT89C51 |
Does anybody know how to design an hour meter using AT89C51 and DS1387 Real Time Clock? An AT89C51 output drives a buzzer when every 1000 hours 0 min and 0 sec has reached. This design may be called as non-volatile timer. But the timer must stop if this hour meter is unpowered. So, it actives only if powered. Can anybody know how to use DS1387 RTC? Thank you. |
