Hi Bill, I did try your suggestion of overflowing TCNT2 & dividing the interrupts by 128, and it worked! But like you said without the caps, there is an error of 1 sec/hour.
So- what are the recommended values of capacitors to be used? Many Thanks, --Royce. On Sun, 23 Apr 2006 05:49:21 +0530, Bill Rochat <[EMAIL PROTECTED]> wrote:
claims that you don't need external capacitors when ASSR is selected, however, without them, there is a time error of about 1 second each hour. I notice that you interrupt 512 per sec. Any particular reason?? I just let the counter overflow TCCR2=0x08. That occurs 128 per sec.
