8051 based programable stopwatch

Hello, I am trying to build a stopwatch which has a keypad to tell to the controller the counting time. But I need some examples about the digital clock by using 8051 assembly code, is there anybody to help me urgently?

hi techexpert,
i think u should see tutorial section for key board interfacing/lcd interfacing and integrate both. then the only thing left would be to write a software timer which would be easy task.
do start on something and we will help u out .
good luck.

techxpert, are you using any IC for stopwatch or a software? obvously a software one.

So i recommend you to go through project "AT89C4051 as RTC" i have used software watch there, you can take it as a reference and work out..
