The DS2423 is part of a 1-Wire weather station. Running oww on the same machine shows the counters as working. I have no problems reading other 1-wire devices, like DS18S20 or a DS2450 with owread/owserver
Any ideas?

I have just plugged into my net a DS2423, and get the same results. I can however read back the family, type, id... but not the memory, counters.A, counters.B, counters.ALL or mincount all come up with 'Data error'

I'm having the same problem. Digitemp reads my DS2423 ok, but owhttpd shows "Invalid argument". Owpython returns random data from memory, often containing piece of the device path.

OK, it looks like I am not the only one with this problem. I am new in this forum (and to owfs), so what is the next step? Are developers reading these messages or should I file a bug report via the tracker?

When trying to owread a counter from a DS2423 I get a data error. In owhttp it shows up as "Error: Invalid argument" insdtead of the counter value.

Checked the CVS repository, but do not know how to obtain the correct devlopment software.
Halp appreciated.

Seems like it was the counter that was broken. A new one works.

Hello,

Looks like the same problem. For me it occurs with the owfs-2.6p4 release as well as the current cvs tree.
I'm having the same problem. Digitemp reads my DS2423 ok, but owhttpd shows "Invalid argument". Owpython returns random data from memory, often containing piece of the device path.

The problems seems to be these three lines in module/owlib/src/c/ow_2423.c:
if (extra[4] != 0x55 || extra[5] != 0x55 || extra[6] != 0x55
|| extra[7] != 0x55)
return 1;
I really don't understand their purpose, but simply commenting them out got it working..
I have this error now.
Running owfs 2.7p4 on slack 12.1.
I can read type, address etc... but not counter data.
"cat counters.ALL" replies "cat: counters.ALL: Invalid argument"
Checked the jpa- reply and the settings in the file ow_2423.c was 0x00.
Really annoying.
Any suggestions?
This was fixed in the CVS some time ago... 2.7p5 should work correctly, so I guess Paul should make a new version as soon as possible.

Hello,
I have just read the datasheet fo rthe said device, and it looks like all these locations should be 0x00 !!

Hello,
Just changed the code on my install to
Works, just fine.
John
I'll try the latest CVS.
