Jerry & others: I was thinking that a personality could be loaded into the chip via owfs (just as a memory write, basically). While I haven't worked on this enough to know the size, I also envision this being an infrequent task (when you first set up a new device, or when you do a major re-purpos

Jim, You are closer to my view of control systems. I generally want susbsystems to be able to act autonomously with the brains doing the more complex work. So it's more like a hierarchy than a pure mesh. I also think about redundancy. Just because 1wire is low cost doesn't mean it can't be use

A PC is definitely more powerful, and its programming paradigms are easier to address, true. However, we've played those games in our OW setup, and have been going back to the "do-it-on-hardware" side. For us, we have a large network of OW devices (often 50+), a PC software suite written by a cou

Yea, we were doing that...We could even read the new voltage and see that it exceeded the alarm threshold, but it didn't alarm. We were actually trying to do most of this through owperl. We had a loop where we would do the simultaneous->convert about once a second, but devices were pretty much al

Just note that it is not sufficient to poll alarm directory to discover units with threshold voltages . The alarm condition is only set after a conversion. You have to trigger this conversion in you polling loop via a simultaneous command. Pascal 2010/2/26 Alessio Sangalli > On 02/25/2010 04:1
