Hello,
I have been working on a project with DS1307 Real Time Clock and DS18B20 One Wire temperature sensor.
As I was running out of pins, I tried out the DS 2415, which also communicates via one-wire. It saved me two pins, and some PCB footprint. However, the 2415 only counts seconds (not days, day of week etc.) and is pretty bare bones.
Therefore, I put together a small library for hte 2415, which allows it to be used very similarly to the 1307. I added a 3V battery to the chip and basically it has the same functionality as the Libelium RTC based on the 1307. It does not have the 1sec squarewave output though.
So switching should be easy. In case anyone is interested, I could distribute the code, but would have to edit.
Prior to this - is anyone interested in i) having a look and ii) testing ?
