| Date: June 2010 | |
| Contact: Christoph Mair <christoph.mair@gmail.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. | |
| What: /sys/bus/i2c/devices/<busnum>-<devaddr>/temp0_input | |
| Date: June 2010 | |
| Contact: Christoph Mair <christoph.mair@gmail.com> | |
| Description: Measure the ambient temperature. The returned value represents | |
| the ambient temperature in units of 0.1 degree celsius. | |
| Reading: returns the current temperature. | |
| What: /sys/bus/i2c/devices/<busnum>-<devaddr>/oversampling | |
| Date: June 2010 | |
| Contact: Christoph Mair <christoph.mair@gmail.com> | |
| Description: Tell the bmp085 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. |
