DS1307 not running?

[richard]

simple explanation for their success is as I said in post 13 .
bit 0 is set as required by the pbp complier .
probably should have said
bit 0 is set and or cleared as required by the pbp complier.
but the book indicates bit0 should always be 0
the 24lcxxx example in the manual makes usage of this (Address) function fairly clear I think

I found #16 a better explanation. Thanks again.
