hi
ths for your reply. actually I read the data sheet already.I still some confused about the subfunction about the DS1302 .my project is quite urgent . can you provide the whole project . I want to learn the sample program about just using 1602 LCD display DS1302. so can you provide the whole programming ??
thanks for your help .

gongyoo, i wish i could provide the code direcly, but its not according to rules of forum. But I am here to help you out.
DS1302 works on very simple 3-wire interface.
the format of reading and writing from clock is given on page 6.
first you send a byte in following format
Bit 0 : Read/Write
Bit 1- Bit5 : A0 - A5 : Address Bits
Bit 6: RC (ram or clock)
Bit 7: always 1

after you send this byte, your next byte will be either data you want to write or read. Please try it once, try writing something.
