hello!
i have been trying to get my rtc running but i can't get it run. i have used the spi before to run my modem and caller id. no problem. but i really got stuck with this rtc. the way i configure my spi for the is:
cpol = 0
dord= 0
cpha = 1
mode = 1
fclk/64
i come to the extend...of wondering does the reading and writing require different setting?! the modem look so much easier to deal than this ds 1306! is there any general rule that i overlooked?
thank you for any reply.
