switching gears to a diff project.... I am using a 4.9152MHz crystal, and part of what I need to do is do some timing delays like 30 seconds, 1 hour, a day and 30 days. So I figured the easiest way is to have registers that decremented for minute, for hour, for day, etc. HOWEVER....looking at the prescaler values for say TMR0, if I use this crystal (that someone else said...use this and it will work fine) each state cycle is .813uS (approx) and if I use the 1:256 prescale I get 208.33mS for each tic for TMR0 and since its just an 8bit value, I can't get one second, best I can get is 1/32 of a second. And of course thats fine, I get the TMR0 interupt and dec a register,etc. Now also someone mentioned to me about using the CCP but I don't quite follow how that might help _________________________________________________________________ Join the world s largest e-mail service with MSN Hotmail. http://www.hotmail.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
