Does it correct your hardware problem?
definitely it improves the situation !
i am now running with 1,8,3 for slewrate, w1l, dso set in my pathon app
as i mentioned some postings ago.
i am able to communicate with
Hi paul,
i was off-duty for the past few days, checked your change today, but no
luck at all ...
according to debug message from USB_Control_Msg the values now get
transferred after changing them - i see this as a huge part of the patch
- but the values set are always the start up (==default)
Dear Paul, dear list,
i finally came up with a patch (against current HEAD) which doesn't
overwrite the changed settings with the default ones ...
please review and merge into HEAD - as i am not 100% sure if the call to
DS9490_SetFlexParameters () is in the correct place ... ;)
thanks,
marcus.

From my experience, I'm successfully operating three ds18b20, two ds2413,
one ds2406 at the far end of my garden on a 120 meters branch using CAT5
cable.
However, parastatic devices where quite unreliable until I added a line
termination as shown in AN132, pg 5, Figure 5.
Dear pascal, dear paul,
thanks for your answers, after another day of measuring and fiddling
around i proceeded some steps further:
adding the add-on circuit for long lines i managed to get
communication with 4 sensors, thats a total of 75 meters with my current
configuration - i managed to
Thanks for the answer !
paul, is it possible to modify these settings from within python ?!?!
if not, then i'll have to rewrite my 1wire stuff ...
regards,
marcus.

I'll look a little closer, but it appears we're overwriting those
Yup,
i found it already ...
import ow
ow.init (u)
ow.owfs_get (/bus.0/interface/settings/usb/datasampleoffset)
' 7'
ow.owfs_put (/bus.0/interface/settings/usb/datasampleoffset,8)
0
ow.owfs_get (/bus.0/interface/settings/usb/datasampleoffset)
' 8'
that should do it ;)
The CVS repository has the corrections. They will b in the next release --
this weekend.

Dear owfs-developers ...
thanks for the great work, i am using owfs for quite some years for my
heating controller and it works perfectly !!!
although currently i have some difficulties ... which i was not able to
get rid of and thats the reason why i am posting here ...
in my current project
Thank you, Marcus, for your kind words.
In truth, I've never had a reason to alter the slew rate, and so can't claim
that code path is well tested. This may be a good opportunity.
I presume you are choosing a slewrate of 0 to 7.
