    +Date: February 2012
    +Contact: Eric Andersson <eric.andersson@unixphere.com>
    +Description: Start a pressure measurement and read the result. Values
    + represent the ambient air pressure in pascal (0.01 millibar).
    +
    + Reading: returns the current air pressure.

    +Description: Measure the ambient temperature. The returned value represents
    + the ambient temperature in units of 0.1 degree celsius.

    +Description: Tell the bmp18x to use more samples to calculate a pressure
    + value. When writing to this file the chip will use 2^x samples
    + to calculate the next pressure value with x being the value
    + written. Using this feature will decrease RMS noise and
    + increase the measurement time.
    +
    + Reading: returns the current oversampling setting.
    +
    + Writing: sets a new oversampling setting.
    + Accepted values: 0..3.
