First, thanks to everyone!
but here I have a question: I have made a digital clock without a MPU, only with some CD4060, CD4017, CD4510...and one 32.768kHz crystal. It work, just the same speed as my watch, so I think the problem is from my program. and also, how can a watch keep it accuracy to about a few second per month? I mean the electronic one. Stanley |
