Hello Jan, I have been running some more tests, again on Jessie, just updated it fully today, rpi-update and apt-get update/upgrade and apt-get dist-upgrade
I put the scope on both, in parasitic and non-parasitic modes. Both look good, I have the images. Again, a cat of '/sys/bus/w1/devices/10.XYZ/temperature' produces a valid temperature, 24c. However using owserver --w1 and owread produces 85c John -----Original Message----- From: Jan Kandziora [mailto:j...@gmx.de] Sent: 01 May 2016 14:31 To: OWFS (One-wire file system) discussion and help <owfs-developers@lists.sourceforge.net> Subject: Re: [Owfs-developers] Raspberry Pi Jessie owfs-3.1.p1 w1-driver = 85c Am 01.05.2016 um 14:58 schrieb Colin Law: > On 1 May 2016 at 12:35, John Bass <j...@johnbass.co.uk> wrote: >> Hello Colin, >> >> You got it, with a 1k resistor(which Jan recommended rather than a 4.7k) >> from VDD to DQ as the pull up.. > > Not from VDD, from 3v to DQ. > Ah, Colin, you are a genius.
