Greetings!
I'm working on a project(A Car lock/general control system) using a
BS2p24.
Now, I really want a realtime clock(not just so that I can display
time on the LCD) but...
I don't have the pins to spare for a 3 wire or I2C chip, so will need
to use a 1-Wire chip of some sort.
(There will be other 1-wire chips on the same bus, most notably a
stack of DS2406 dual switches)
The DS2417 looks like the thing since it can also be set to give
interrupts, but unfortunately, it just counts seconds...
Does anyone have any good ideas to do FAST conversions to get this
over to YY:MM[noparse]:D[/noparse]D:HH:Min:Sec?
Or any other chip that can do the job?
