I can confirm that using a DS2480B together with an FTDI serial/usb converter runs fine on my RPi since I upgraded the RPi Firmware. Before I had serious problems with the FTDI usb driver.
Inexpensive adapter I'm using can be found e.g. here: http://www.meraprojekt.com.pl/mp00202.html BR Ralf -----Original Message----- From: Sven Geggus [mailto:[email protected]] Sent: Monday, 04 February, 2013 13:49 To: [email protected] Subject: Re: [Owfs-developers] Everything on Raspberry PI Guy COLIN <[email protected]> wrote: > Just to give information about owfs running on Raspberry pi, with > latest Raspbian and owfs from the repository of the distribution. > Everything is just perfect Hm, my impression is not that perfect. There are 3 ways of connecting 1-wire to Raspberry PI which I tried but only two of them work. I did not try to use the serial port though. The most simple way (using GPIO and bit-banging) does not work with owfs (see below). 1. Using a DS9490B works fine 2. Using I2C an a DS2483 works fine (need option "--no_PPM" on owfs version from raspian wheezy, no additional option with current version of owfs) I use the following schematic http://home.geggus.net/pub/raspio.pdf which also includes galvanic insulation between raspio and 1-wire/I2C 3. Using In-kernel w1-driver and bit-banging on gpio (most simple hardware-wise) will not work with owfs. This will produce a kernel oops and has been broken since kernel version 2.6.39 (March 2011). I tracked this down to the faulty commit, but unfortunately, there is no fix yet. Regards Sven -- Das Internet ist kein rechtsfreier Raum, das Internet ist aber auch kein bürgerrechtsfreier Raum.
