MOD-RTC not working with PIC32-PINGUINO-MICRO

[Stanislav]

Hello,

UEXT module MOD-RTC (there is a battery) is not working with PIC32-PINGUINO-MICRO, I download the program "MOD-RTC example" loaded to board but, every time the same massage:

Time & Date:
0:0:0
D/M/Y: 0.0.0
Day of the week: Sunday

Change the declaration from:flag = set_time_date(0,0,0,0,1,1,0);
to: flag = set_time_date(0,34,10,3,1,12,12);

But not, same.. 000
It is look like the Clock it Ticking  , Any ideas Why?

I modify the program from "regis blanchot" he give it to me, and I find it very useful:

Well, on the pinguino.cc forum it is said that the PIC32-PINGUINO-MICRO indeed HAS a built-in RTC,
but you need to solder on a 32 kHz crystal and 2 capacitors.
