Re: Data error reading DS2423 counters

Hi

I run 2.6p3-4 which is the latest port to the slug.

Previous versions don't support the AAG thermocouple device (DS2760) which I need as part of my setup.

DS2423 counters did work in 2.6p1-3 but the DS2760 didn't.

thanks

I run  a DS2423 on an NSLU2 and it works fine....

Hi all, FWIW all my DS2423 devices on the slug are now reading errors. Does anyone remember which version these still worked for?

I've been looking at the code.

Can you post what kind of errors you are getting? Perhaps debug output?

owserver doesn't seem to actually log anything special.
A Hacker's Guide (or, if it already exists, a pointer to it) which
gives one a few pointers WRT where to start finding that kind of problem
would be appreciated.

Ok, sounds easy to fix.

why are there 3 x owservers running on my SLUG (NSLU2)

I have noticed using "top" that owserver takes 16% of my little slugs memory when idle and 29% when my owread script kicks in..  This has led me to wonder why I have three owservers running on my slug. 
 
The only owfs services script remaining is the S70owserver script.  The other startup scripts (S80owfs, S80owftpd, S80owhttpd) I have moved out of /opt/etc/init.d so they do not startup.  I only have one data gathering script which continuously runs and polls 1wire data every 90 seconds.  This script uses owwrite owread commands.
 
I have used the standard ipkg install process..   Anybody know why I have three owservers running ?

Re: why are there 3 x owservers running on my SLUG (NSLU2)

Hi Rob

Your message prompted me to check the processes on my slug.

PS looks a bit scarier than yours.

Why aren't old processes dying I wonder

Maybe more importantly why are new ones starting?

I 'm polling it every min to get data but I don't see why that would start processes. Not using owread, just "cat filesystem > myfile"

Re: why are there 3 x owservers running on my SLUG (NSLU2)

owserver is multithreaded -- might separate threads appear as separate processes in uclinux?

Subject: [Owfs-developers] why are there 3 x owservers running on my SLUG (NSLU2)

 

I have noticed using "top" that owserver takes 16% of my little slugs memory when idle and 29% when my owread script kicks in..  This has led me to wonder why I have three owservers running on my slug. 

 

The only owfs services script remaining is the S70owserver script.  The other startup scripts (S80owfs, S80owftpd, S80owhttpd) I have moved out of /opt/etc/init.d so they do not startup.  I only have one data gathering script which continuously runs and polls 1wire data every 90 seconds.  This script uses owwrite owread commands.

 

I have used the standard ipkg install process..   Anybody know why I have three owservers running ?

Re: Data error reading DS2423 counters

I had problems with 2.6p1-3 with DS2423 devices on an NSLU2 and problems 
(less) on Debian.
In both instances I was using USB.

I eventually reverted to an old serial adaptor which worked.

Re: Data error reading DS2423 counters


I have changed the if-statement for the ds2423 which probably caused the
problem.
I also built new nslu2 and openwrt ipk-packages with this update.

DS2760 - two bugs

Hi all,

running 2.6p4 on a FC5 I get some wrong readings from a DS2760 (like -31 C
as room temperature...)

Bug 1
After some debugging I found that OW_r_int(...) (line 886 in ow_2760.c) is
returning the temperature bytes from DS2760 in reversed order. OW_r_int
has another way of reading the bytes (line 1043 in ow_2760.c) but this is
commented out.

Swapping comment of line 1043 and 1044 in ow_2760.c gives the right
temperature reading, but I can't figure out if this is the right way to do
it or if there is a general bug in UT_int16() (or maybe OW_r_sram()).

Bug 2
But still I get the wrong thermocouple temperature. After some more
debugging  I realized that an old bug has been reintroduced (see e-mail
from 5/23/06): FS_r_vis() has a special if-statement for DS2740BU (line
617,618 in ow_2760.c) which is only relevant for DS2740BU (or am I
wrong?).

After moving it to the case-statement of DS2740 (as it was in version
2.3p7) I got the right readings from the thermocouple.

Does anybody know why this if-statement has been moved??

A diff of my changes is included below.
