Hi Mark,
Thanks for the reply,
Did exactly what you said,
Completely new chip from RS (out of the packet), New Xtal, Gnd & VCC on a breadboard. not recognized.
Connected a 3.3V to the Pin 3 batt input, still nothing, still not recognized
Plugged in the PCF8583 into the same (new) circuit, and the PCF chip circuit works and is recognized straight away.
Tried 5 different crystals, even took the crystal out of the working PCF circuit and put it in the DS circuit, and it didn't work.
And all of the 5 xtals work in the PCF circuit and they did work.
Think I might just give up and put get PCF8583 chips on the PCBs (which are cheaper by $1.00) and put the address as A2 using pin3, as the base address for the PCF (A0) would clash with the EEprom (also A0)
Regards
Deanus
