1. Simple adapters (the DS9097E) work well with OWFS. We had a problem with them 1.5 years ago, but it's been solved. In fact some of my production monitoring uses them, with uptime >9 months.
2. Leonid's adapter seems to use the same RS232 control pins and power source, so I'm not surprised it works, just wanted to confirm. In that case, I'll just add the Vcc control and a filesystem interface, and the DS1821 will be supported. 3. We will still have the same "semi-blind" problem with the DS1821 -- it doesn't support 1-wire addressing. 4. There are a few non-addressable 1-wire chips. The DS1821, DS2705, DS2434 DS2435 ... (see http://www.owfs.org/index.php?page=standard_slaves). I wonder if we shouldn't have a better way to support them. A. Move them to a new "NoAddress" directory (need a better name) B. In "NoAddress" use a (slow) blind dialing approach to see if any respond.

Krzysztof, can you tell me if the adapter works with >> standard 1-wire devices and OWFS? >> that is funny (maybe it is not, I will compare shematics later, http://www.elektroda.net/dla_kompa/ds1820/ds9097e.gif looks similar) but that interface DOES work with 32bit timex API! I did that adaptor like Lenoid wanted and it works with _his_ program and ds1821. Then I have disconnected 1821 and put 1820 in the place, and Timex viewer does show that device! I did not test any other DS**** that I own. I will check owfs later and post my results here. In the past you told me that simple http://www.elektroda.net/dla_kompa/ds1820/ds9097e.gif adaptors simply does not work with owfs, or I have a memory hole in my brain? ------------------------------------------------------------------------- Using Tomcat but need to do more?
