In Reply to: Need a circuit design for setting time in a digital clock! posted by Imdad Saiyed on 12/22/02 at 2:17 PM:

Greetings. Re your clock -- what clock chip are you using? Is your clock a commercially-produced one, or have you constructed a clock circuit yourself? Most current commercial designs (Cosmo, etc)use a pulsed system derived from the AC line frequency to "clock" the "set" (hours & minutes) terminals of the chip whilst another "set-select" terminal is held down. I am not too sure why you would require something different from what the clock-chip manufacturer has provided, but --- I am ready to be convinced.

Please advise.

BS
