I recently purchased the basic components to experiment with one-wire. T/H/S sensor, cable and Serial adapter along with Tim's book.
I was happy to get the Temp sensor working with the simple weather code from the book.
I'm not having any luck with the humidity or solar sensor. The Humidity/Solar DS2438 shows up ok with OneWireLister. When I add the Humidity code to simple weather - it runs but gives no results. I've added in the solar code from the bonus downloads and same thing - it runs without error - just no results. I have tried with and without external power, with and without the internal jumper. In every case , Simpleweather with debug on gives me the following:
Found Adapter: DS9097U on Port COM1
Resetting 1-wire bus
Temp Device Supports High Resolution
Time = Sun Oct 21 13:29:42 EDT 2007
Temperature: Device = DS1920 ID = 6D000801550A7110
Temperature = 75.0875 deg F 23.937502 Deg C
Humidity: Device = DS2438 ID = E6000000B6592A26
Supply Voltage = 0.0 Volts
Sensor Output = 0.0 Volts
Temperature = 0.0 C / 32.0 F
Uncomp RH = NaN%
Hum Gain = 1.0
Hum Offset = 0.0
Calibrated RH = NaN%
Humidity = NaN %
Solar: Device = DS2438 ID = E6000000B6592A26
Supply Voltage = 0.0 Volts
Sensor Output = 0.0 Volts
Gain = 1.0
Offset = 0.0
Comp Solar = 0.0%
Solar Level = 0.0%
Any hints on where to look next? It seems like the DS2438 is responding but if the response is correct, it has zero supply voltage.
