Posted on February 20, 2013 at 20:58hello,
after long trying, i managed to write to the pcf8574
in assembly language.
no i have only a problem with WRITING to the DS1307, i can read the DS1307
my question is, when you use a crystal of 14.7456Mhz, what are the correct settings in the freq ,and ccrl registers, because i have connect the DS1307 to the AARDVARK and i can write and read.
are there special precautions for write to a DS1307
many thanks
