Maybe this week I will make a prototype board for it and then test with my current network which now runs on DS2480B. My network wiring is very bad so it should be a good test. As I wrote before I experienced very long response time with i2c-tiny-usb which had claimed speed about 50 kHz. The OSIF is much faster although they say it's not that simple and with some operations slower. Did you use some i2c-usb converter? I have also some other i2c 1wire masters maybe they will be more promising if DS2482-800 turns to be slow. Just now on the breadboard I connected my old network to bus.0 and got similar times like on my router with DS2480B directory listing with 10 devices 8 DS18B20 1 DS2428 clone and DS2408 takes 2.5 seconds and reading 8 thermometers and ~16s to read temperature. More testing next week. -- p4trykx ------------------------------------------------------------------------------ For Developers, A Lot Can Happen In A Second.
