Oh good, so I do not have to ask for GPL clearance and all, I guess, because this looks quite trivial and could have been derived by anyone who's got the actual hardware at hand. Especially as the hardware is being sold as a kit with a half-finished PCB meant for self-construction, so no forbidden reverse engineering here. Would you be able to add support for that device to owfs with that information? I would gladly order one to test it! There is one other company, their web site is http://www.1-wire.de , which will release a 1-Wire LCD Module hardware soon, too. The developer told me he would release the code for that. It's probably not going to be much different from the two other boards we have mentioned in this thread, anyways. Oh, by the way, my home one-wire network with its 6 sensors, 25 meters to the unswitched splitter, and branches from the splitter between 1 and 6 metres length, turns out to be a pure nightmare in terms of reliability. Sometimes, for no apparent reason, all the readings on the longer branches fail, then one hour later, it suddenly pops back to normal. I know , I've been warned! ;) That is why I want to correct the network topology, although I have to stick with a "central hub" every sensor cable ends at, in order to make the place look less cluttered and keep it service-friendly should there be any changes. I am planning to use a regular 8-port ethernet CAT5 LSA "punch down" patch panel to plug in all the sensor cables, add the proper wires to it, and modify the CAT5 cables leading to the sensors to create a real "daisy chaining" topology. Is it sufficient to daisy-chain the DATA line, and can GND and +5V still remain in "stubbed" topology, or should I run all of these wires through (i.e. back and forth via separate wires) all of the sensor cables, too? Either way is possible, as I've got 4 wire pairs per sensor cable. Should GND and DATA go twisted with each other? Or data[going to sensor] on the same twisted pair with data[coming back from sensor] ? Philipp ------------------------------------------------------------------------- Take Surveys. Earn Cash.
