Mon, 01 Dec 2008 12:41:20 -0800 http://backend.userland.com/rss092 I need to design a stopwatch that counts to 99.99 using 8 led's in a row (number will be displayed in BCD). I was thinking that I would utilize the O <noauthor@nospam.com> http://www.8051projects.net/forum-t9850.html use Timers with prescaler for dividing the clock.Its easy to make a stop watch with approximate accuracy in PIC. Ajay<contact@nospam.com> http://www.8051projects.net/forum-t9850.html Would it be best to use Timer1 over Timer0 or does it not matter which timer I use? Any other advice? thanks matlark<matlark@nospam.com> http://www.8051projects.net/forum-t9850.html I really doesn't matter you which timer you are using. but the important thing is... is that timer capable of generating the time delay you need.. Ajay<contact@nospam.com> http://www.8051projects.net/forum-t9850.html I am having trouble coming up with how I need to break the timer up. If I use maximum prescale so that I have approx 3906.25 instructions per second. matlark<matlark@nospam.com> http://www.8051projects.net/forum-t9850.html I think you are getting me wrong prescaler will only divide the clock input of timer not the CPU, cpu will execute the instructions normally where as Ajay<contact@nospam.com> http://www.8051projects.net/forum-t9850.html
