Hi,
In case this is of interest to anyone here, I've written a bit of code which shows how a DS1302 real-time clock/calendar device can be accessed in Java ME.
You can have a look here https://github.com/j-mbd/short-and-quick/tree/master/src/jmbd/ds1302
(Tested on RasPi 2 Model B running the 8.3 SDK)
