I've updated to the latest NSLU2 build of owlib/owfs/owshell (2.6p2-3) and
continue to be unable to read DS18S20 sensors through a DS2409 microlan
coupler. The thing is, I *can* read the DS1820 in my V1 weather station. I
tried reading both devices using owread and made sure the conditions were the
same (unexpired entry in cache while reading uncached value). The results are
the same whether reading cached values, uncached/expired, etc. The debug output
from owserver is below. I don't see any real differences between the two, yet
the DS18S20 consistently fails while the other consistently works. This worked
OK in earlier versions (2.5p10 I believe) and digitemp reads the sensor just
fine, so I don't think the bus has changed any. The same sensors work if *not*
connected through the hub. That makes is sound like owfs is doing something to
the hub during the read that disrupts the DS18S20, but not the older DS1820. No
evidence to support this, just guessing.
At this point I'm at a loss. I don't know what other debug info to collect,
what I have isn't telling me anything, and my sensors still don't work :\ Any
ideas for further debugging?
Thanks!
Paul
