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

2010-01-27 Thread Jerry Scharf
Sophana, First, I drive my sensors from python through owserver, so a simple example probably won't help you. I don't think that "on their own segment" is enough because the sensor can't know that, but this is beyond my level of knowledge about 1-wire. What I do is set the simultaneous convert

Hi I made the tests on powered sensors. Some other sensors are not powered but they are "alone" on their own hub segments. You don't need to write to the simultaneous/temperature file? Just do parallel access to owserver? Or do you do both? Can you give an example of access sequence you are doing?

Sophana, I am sure this works. I have a hub (not a switch) and do simultaneous reads for my 30+ temp sensors. Do you have separate power or are you running in parasitic mode. I am fairly certain you can not do simultaneous reads with parasitic power. jerry Sophana K wrote: > On Mon, Jan 11, 2
