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.

well there is no limit, but its better to stick to single thread till your problem is different. Like now you have posted in a new thread whereas it could be done in the previous thread only.
