DS1994 i-Button Real Time Clock

[crhomberg]

I like your style,

Keep it simple and functional. I think I am going to do it exactly as you say except I think to control the device I will include a iButton eeprom with a code on it which will come with the installation and another with another code telling the pic to just keep output on.
Have you any code on reading and writing to iButton EEPROM? else I will just plough through the datasheet and work it out the long way.

Thanks & best regards

Hi to all I thought maybe a good solution is a small PIC, a iButton eeprom with a code with a date and another that just keeps the output on with a small realtime clock inside which I can set before sending the switchboard off. (maybe a DS1302) I will still have the ibutton exchange system but without having to set the DS1994 .
