Indeed. Unfortunately onewireviewer won't even give me raw scratchpad data. It seems to me that since the temperature (ds1825) and CJC compensated temperature (31850) are in the same place (bytes 0-1) they should both be delivered to 'temperature' and CJC (1-2) should be in an auxiliary

Hello all, I have a Datanab TC to 1Wire that uses a MAX31850: http://www.datanab.com/sensors/1wire-%20thermocouple-sensor-thrmcpl_k.php The device reads fine using a DS9490R on Windows using a package I have written to read the device as in the datasheet (OneWire Viewer does not read
