real time clock

[longpole001]

I know this is old thread but have a need fro RTC and its using the ds1302

i did have a quick question in relation to how the I/O port is set on the PIC for I/O the interface to the DS1302 , in that the sample code does not change TRIS bits on the PIC from an output to an input for when it doing a read ( shiftin command ) of the DS1302 -

does issuing the shiftin command automatically change the tris bits for that port to allow input ???
cheers

Hello longpole, i've been reading the thread today and some others about 1302 and i think shiftin and shiftout does all the work with tris and with clk. Just send the right registers for reading/writing and u should be fine.
