1 What: /sys/bus/i2c/devices/<busnum>-<devaddr>/pressure0_input 2 Date: June 2010 3 Contact: Christoph Mair <christoph.mair@gmail.com> 4 Description: Start a pressure measurement and read the result. Values 5 represent the ambient air pressure in pascal (0.01 millibar). 6 7 Reading: returns the current air pressure. 8 9 10 What: /sys/bus/i2c/devices/<busnum>-<devaddr>/temp0_input 11 Date: June 2010 12 Contact: Christoph Mair <christoph.mair@gmail.com> 13 Description: Measure the ambient temperature. The returned value represents 14 the ambient temperature in units of 0.1 degree celsius. 15 16 Reading: returns the current temperature. 17 18 19 What: /sys/bus/i2c/devices/<busnum>-<devaddr>/oversampling 20 Date: June 2010 21 Contact: Christoph Mair <christoph.mair@gmail.com> 22 Description: Tell the bmp085 to use more samples to calculate a pressure 23 value. When writing to this file the chip will use 2^x samples 24 to calculate the next pressure value with x being the value 25 written. Using this feature will decrease RMS noise and 26 increase the measurement time. 27 28 Reading: returns the current oversampling setting. 29 30 Writing: sets a new oversampling setting. 31 Accepted values: 0..3.
