- What: /sys/bus/iio/devices/iio:deviceX/calibration_auto_enable
- Date: June 2020
- KernelVersion: 5.8
- Contact: linux-iio@vger.kernel.org
- Description:
- Contaminants build-up in the measurement chamber or optical
- elements deterioration leads to sensor drift.
- One can compensate for sensor drift by using automatic self
- calibration procedure (asc).
- Writing 1 or 0 to this attribute will respectively activate or
- deactivate asc.
- Upon reading current asc status is returned.
- What: /sys/bus/iio/devices/iio:deviceX/calibration_forced_value
- Date: June 2020
- KernelVersion: 5.8
- Contact: linux-iio@vger.kernel.org
- Description:
- Contaminants build-up in the measurement chamber or optical
- elements deterioration leads to sensor drift.
- One can compensate for sensor drift by using forced
- recalibration (frc). This is useful in case there's known
- co2 reference available nearby the sensor.
- Picking value from the range [400 1 2000] and writing it to the
- sensor will set frc.
- Upon reading current frc value is returned. Note that after
- power cycling default value (i.e 400) is returned even though
- internally sensor had recalibrated itself.
