Dear All,

I am trying to build a stop watch using atmel 8051 series controller,
It should be capable to display 10,000 hours or more.

Can anybody help me? please!!!!!!!!!!! If possible anybody can suggest
two digit stop watch also, I would love suggestions from you all.


Get a serial or paralell LCD interface, unless you are using a version
of the micro with an adequate built in raw LCD interface.

The software is easy, just timing loops timed from a 32768 hz watch
oscillator, or better.

How hard is a 60KHz WWBV calibrator? ;-)
^^^^
WWVB


WWVB in India?

Duh.

Never mind. (albeit WWV does transmit on 2.5, 5, 10, 15, and 20 MHz.)
