hello,

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

marc debruyne
