Hi There,
I bought a DS1302 (see here : Recommendations For You - DealeXtreme ).
I use this piece of code : Arduino Playground - DS1302 (or also a library from here : arduino-ds1302/DS1302.h at master · msparks/arduino-ds1302 · GitHub).
However, I am getting wierd result.
The time I see is not one the one I read afterwards.
When setting time for exemple, it affects the date...
Here below my sketch.
Anyone has ideas?
I get this as output : "08:17:09 21.09.2001 Sun" whereas my code sets : rtc.setDOW(SATURDAY); rtc.setTime(16, 1, 3); rtc.setDate(7, 9, 13);
Thanks,
Erwan
