How do you save data in more than one slot in the DS1302 time chip Example given ..>
How would put the next event in the next memery slot and know when the memery slots were full ?
I know how to put Data each memery slot with the VAR WORD
I want to put more than one Event_seconds in memery
Is there a way to this with out doing that way
I can get this to work how ever I do not want to use a computer to use this I want the Basic Stamp to save the even which i can not get this to work
