Hello all,

Has anyone looked into using the iButton cans (www.ibutton.com) from Dallas
Semi? They use a 1-wire interface which probably would work with a PIC,
though there may be some issues dealing with the 115kbit/sec transfer rate.
These things seem like a great application of the PIC, which could provide
a gateway to real-world elements using the DS1990 as an authentication
tool. Am I totally wrong here? Sorry, I've been lurking in this group for a
while, and haven't made the leap from Stamps to PICs, so I'm not really
familiar with the throughput possible with an entry-level PIC.

Thanks,
 Nathan
