RTC stop working with button cell
#1
I am having problems with the DS1307 RTC. It works fine when it is not used with the CR1220 button cell backup. When the CR1220 button cell is inserted the time cannot be set up and it always read 2165/165/165 (Saturday) 165:165:85. I have tried two CR1220 button cells, one of them new,  and I have checked that they provides 3 V.  Any suggestion?
