Stop watch, please help

[911]

Im currently working on a project with Pic 16f877, simulating a stopwatch with 3 seven seg display. 1 shows munite, and other 2 show 00->59 secs.
Can someone give me a sample code for it? I just need a counter of TMR1 and update the display every 1 sec. No buttons.
I will be so grateful for any replies.

Use timer2, it's a lot easier - I'm currently playing with timer2 running a clock - displaying hours, minutes, seconds, and hundredths on an LCD module. I'll probably be adding it as a tutorial later this year - from what I've got so far it would be extremely simple to add stopwatch facilities, and I'll be doing so as part of the tutorial.

Send me your email address in a PM and I'll send you my existing code when I get home - what clock frequency are you using?.
