Hi, I'm pleased to announce the BAE0910, a new multifunction 1-wire slave device! Functions such pulse width modulation and embedded logic are now possible on your 1-wire network. The BAE0910 was the missing link of most 1-wire projects. Main features: - 1-wire compatible - up to four PWM

Re: [Owfs-developers] simultaneous temperature reading with hubs

itiating a voltage conversion on present ds2436/38 devices. But this should not harm any project. The only issue will be false presence of unpowered temps sensors and thus forcing the waiting. which is allways working. Sorry for this long post :-/ Pascal 2010/1/28 Paul Alfille > > >

Re: [Owfs-developers] simultaneous temperature reading with hubs

Hi, I'm also concerned by responsiveness of temp readings. Here my experience: First, the ds18b20 chips are not continuously converting temperature themselves , they only start a measurement when they receive a convertT command from the master. The conversion require up to 750ms for at 12 bits res

Re: [Owfs-developers] PIO problem using NSLU2 (Unslung) , HB 8 channel I/O (DS2408) and owfs - 2.7p21-1

I confirm that at least ds2406 is working OK with both pio.byte & bits on my nslu2 platform. However this is a debian-based slug (thus little-endian) with latest svn. This indeed seem to indicate an endianness issue. I will also check if I have a ds2408 avail to confirm with this chip too. Pascal

>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. http://pdfserv.maxim-ic.

Re: [Owfs-developers] Two DS2482-100 on 1 i2c bus

Hi again, humm, just discovered another reason that can explain your problem: If you have revision A2 of the DS2482-100, bad luck for you... see this errata from maxim: http://pdfserv.maxim-ic.com/en/errata/2482-100A2.pdf Pascal 2009/8/15 Pascal Baerten > Hi, > > I 'm using two

Re: [Owfs-developers] Two DS2482-100 on 1 i2c bus

Hi, I 'm using two ds2482-800 on the same bus without problem so I don't think that it is software related. (however I didn't upgraded recently still 2.7p21) You may issue this command to discover chips present on the i2c bus: i2cdetect -a 0 result for me: I will probe file /dev/i2c-0. I will pro

Re: [Owfs-developers] Notification or polling switch/presence

Hi, I'm polling an one-wire network that will contain more than 30 DS18B20 powered temp sensors along with other lcd and switches. As suggested, I use the simultaneous to initiate conversion on all sensors allowing me to do some other bus activities during conversion (750ms for 12bits). Later, onc

[Owfs-developers] DS2482: APU and PPM configuration not reflected in HTTP interface/settings + overdrive not implemented

Hi, The new settings ActivePullUp and PulsePresenceMask are always shown as checked in interface/settings. However, after placing some tracing, in SetConfiguration(), I confirm that settings are modified as requested. For overdrive, the problem is exactly the reverse: the shown setting change as

[Owfs-developers] owhttpd via owserver does not allow selecting a (sub)channel on ds2482

Humm, sorry for reporting so actively... everything is fine when starting owhttpd directly on the physical interface. However, when I work via owserver like this: owserver --i2c=/dev/i2c-0:ALL -p 40666 --error_level 9 --foreground owhttpd -s piccolo:40666 -p 81 I can see and control all connecte

Hi, I've also searched for such equipment however, I didn't find an acceptable solution. I still have such need today and foresee in the near future for a small development based on DS2740 and a coulomb captor. I already ordered samples from Dallas and found also a small current transducer ( LTS
