Hi there,
in my application I have some Ibutton locks I need to scan. The locks are
connected through a DS2482-800 onewire host.
I expected scanning a single key on an otherwise empty bus (reading
bus.0/uncached) would require a single reset pulse, presence pulse and then
about 200 onewire bits. I suspected that operation is done in about 10..20ms.
In fact, scanning takes about a second, which makes me wonder where I'm wrong.
Any idea how to make scanning faster -- or, even better, to get rid of
scanning? Maybe there's a µC driven gadget out there which contineously scans
a single lock and reports the lock's state as its onewire data instead of an
address.
Kind regards
Jan
