Again, a Linux noob here, so bear with me if I'm doing something dumb. I got OWW 0.86.1 to build and run (0.86.2 gives me "buffer overflow" errors at runtime so I backed up a version) under Ubuntu 12.10, both on a desktop PC and on a Beaglebone (with the nogui option). Having selected /dev/ttyUSB0 as my port, OWW then sees all the 1-wire device ID's on the net. However all data is displayed (output to client for nogui version) as zero values. Any ideas what I could be doing wrong? Devices file (as written by OWW) is as follows:
My first suggestion would be to turn on debugging output. The output to the terminal and to file are controlled by messagelevel and debuglevel respectively in your setup file.

Any help is appreciated - my ultimate goal is to run this on the Beaglebone and free up the PC.

Hello Brian.
My first suggestion would be to turn on debugging output. The output to the terminal and to file are controlled by messagelevel and debuglevel respectively in your setup file.
Please see http://oww.sourceforge.net/oww_setup.html#setup for the various levels of verbosity.
Is even the temperature coming out as zero?

Simon
