Bob thanks for your reply, the time display issue seems to be solved now.
What I am still struggling with is the module configuration. To set it to 17:31:00 Monday, 2-7-2007 I am doing the following on setup()
Wire.beginTransmission(104); // transmit to device #104, the ds1307
Wire.send(0);
Wire.send(0x00);
Wire.send(0); //sec
Wire.send(31); //min
Wire.send(17); //hour
Wire.send(2); //day
Wire.send(2); //date
Wire.send(7); //month
Wire.send(7); //year
Wire.endTransmission(); // stop transmitting
delay(100); /* */
when printing back the values, I get:
21:05:32 Sunday, 2/2/2007
something its obviously not working..
