Oh.... Sorry... I looked at the actual values written to the adapter.. I added an offset to Writeonelowtime and datasampleoffset to show "micro seconds" instead of the raw value. Therefore the correct initialization should look like:
Starting owserver without --altUSB option is the same as setting: bash-3.2# echo 1 > /tmp/1wire/bus.0/system/adapter/overdrive.0 (flexible speed) bash-3.2# echo 5 > /tmp/1wire/bus.0/system/adapter/pulldownslewrate.0 (0.83V/us) bash-3.2# echo 12 > /tmp/1wire/bus.0/system/adapter/writeonelowtime.0 (12 us) bash-3.2# echo 7 > /tmp/1wire/bus.0/system/adapter/datasampleoffset.0 (7 us) Starting owserver WITH --altUSB option is the same as setting: bash-3.2# echo 1 > /tmp/1wire/bus.0/system/adapter/overdrive.0 (flexible speed) bash-3.2# echo 3 > /tmp/1wire/bus.0/system/adapter/pulldownslewrate.0 (1.37V/us) bash-3.2# echo 10 > /tmp/1wire/bus.0/system/adapter/writeonelowtime.0 (10 us) bash-3.2# echo 8 > /tmp/1wire/bus.0/system/adapter/datasampleoffset.0 (8 us) (This setting have been reported to work for some AAG user before) /Christian > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:owfs- > [EMAIL PROTECTED] On Behalf Of Giuliano > Sent: den 5 juli 2007 02:15 > To: [email protected] > Subject: Re: [Owfs-developers] NSLU2 and DS2408 (flexible speed is now > default) > > Christian Magnusson <mag <at> mag.cx> writes: > > > > > > > Starting owserver without --altUSB option is the same as setting: > > bash-3.2# echo 1 > /tmp/1wire/bus.0/system/adapter/overdrive.0 > > bash-3.2# echo 5 > /tmp/1wire/bus.0/system/adapter/pulldownslewrate.0 > > bash-3.2# echo 4 > /tmp/1wire/bus.0/system/adapter/writeonelowtime.0 > > bash-3.2# echo 4 > /tmp/1wire/bus.0/system/adapter/datasampleoffset.0 > > > > Starting owserver WITH --altUSB option is the same as setting: > > bash-3.2# echo 1 > /tmp/1wire/bus.0/system/adapter/overdrive.0 > > bash-3.2# echo 3 > /tmp/1wire/bus.0/system/adapter/pulldownslewrate.0 > > bash-3.2# echo 2 > /tmp/1wire/bus.0/system/adapter/writeonelowtime.0 > > bash-3.2# echo 5 > /tmp/1wire/bus.0/system/adapter/datasampleoffset.0 > > (This setting have been reported to work for some AAG user before) > > > Removed with ipkg both owlib and owfs.
