|

* @brief Driver for the Texas Instruments HDC1000
|
||||
* Humidity and Temperature Sensor.
|
||||
* The driver will initialize the sensor for best
|
||||
* resolution (14 bit). Currently the driver doesn't use the heater.
|
||||
* Temperature and humidity are acquired in sequence.
|
||||
* The sensor is always in sleep mode. The measurement must
|
||||
* be started by a write access to the address 0x00
|
||||
* (HDC1000_TEMPERATURE). After completing the measurement
|
||||
* the sensor will return to sleep mode. Typical
|
||||
* Conversion Time by 14 bit resolution is 6.50ms
|
||||
* for humidity and 6.35ms for temperature.
|
||||
* HDC1000_CONVERSION_TIME is twice as large to prevent
|
||||
* the problems with timer resolution.
