A minor release, mainly to get the Datanab humidity support out there. New release 2.8p10
1. Support for the DataNAB humidity sensor. 2. Don't cache empty directories The DATNAB humidity sensor uses the familiar HIH-4000 sensor and the DS2438 like the other humidity sensors, but measures sensor voltage with the current sensing pins rather than the VAD pins. It appears they use a voltage divider to bring the voltages into the correct range. They also use the on-chip memory to store calibration data and an identifier. OWFS will now search for the identifier on initial scaning of the DS2438, and change it's behavior if it's found: 1. Calibration data will be read and stored 2. DATANAB directory will become visible 3. The current readings will start and the offset will be set to 0 4. Humidity will point to the correct scheme. http://www.datanab.com/sensors/1Wire_tempHumProbe.htm Note that the same scheme could be expanded to iButtonLink's MULTISENSOR designs. This is a series of DS2438-based chips that have on-board identification, albeit with only a single byte that might lead to more erroneous assignments. ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
