Re: [Owfs-developers] Odd 85 deg temperature readings again

2006-12-05 Thread Mark Richards
Dallas had an issue with 18B20, 18S20, 18B20-PAR, and 18S20-PAR devices, known famously as the "C3" Die problem, some time ago. It is characterized, as I am told, by repeated 85C readings returned from the device caused by a failure of the chip to properly POR. The fix involves issuing an "ex

One more item... Regarding measuring sunlight, there's a nice "calibrated" reference cell that's cheap which might work for general purposes. We decided to go with a photodiode that has a wide lens and narrow bandwidth and with some circuitry that lends stability and an output calibrated in W/m2.

The DS2436 is a rather nifty chip in that it can measure its own VDD, which gives it the ability to act as a general purpose A/D device. However, the input is limited to between 2.4-10VDC when operated in non-parasitic mode (performance degrades below 2.4vdc). It is capable of running on parasiti

Paul, Thanks. I was actually looking for the source that sets up the T_Conv call to all the devices on a given segment. I bet there will be some wisdom in there that I can learn from. Or, is this just done as a matter of course in 1WFS? /m >>There is a directory called "simultaneous" if th
