Hi,
Any help with this would be much appreciated.
I have built a 1-Wire weather station as directed by Tim Bitson's book. All was working fine except for my solar sensor was giving me this error:
Error Reading Solar Sensor: com.dalsemi.onewire.adapter.OneWireIOException: OneWireContainer26-Bad CRC during read.99
Solar Level = -999.9 %
Thinking it could be software related (because the solar code is an addendum to the book) I posted it on the Bitson's weather forum and he suggested installing a 100 ohm resistor. I did that, but still no luck.
I decided that it must have been some damage that I caused to the board... (though I'm pretty careful) So I ordered a new complete temp/humidity/solar sensor. It just arrived moments ago and this time none of the sensor seem to work:
Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7
Error Setting Resolution: com.dalsemi.onewire.adapter.OneWireIOException: OneWireContainer10-Error reading CRC8 from device.
Error Reading Temperature: com.dalsemi.onewire.adapter.OneWireIOException: OneWireContainer10-Error reading CRC8 from device.
Temperature = -999.9degs F
Error Reading Humidity: com.dalsemi.onewire.adapter.OneWireIOException: OneWireContainer26-Bad CRC during read.99
Humidity = -999.9%
Dewpoint = NaN degs F
Error Reading Solar Sensor: com.dalsemi.onewire.adapter.OneWireIOException: OneWireContainer26-Bad CRC during read.99
Solar Level = -999.9 %
I know I should just email Hobby-boards and ask for help, but I also thought it might be good to have this on the forum in case others experience it.
All three sensors show up in the OneWireLister and OneWireViewer. I'm on a Mac - using the ds9097u with a keyspan.
All of my other sensors work fine. I've tested the board with and without the other sensors attached. I have only used parasitic power. I am not using a barometer. My current cable length is about 6 feet (but have also been using 30+). I've only tried it w/o the jumper.
Any help?
Bart
