What: /sys/.../iio:deviceX/in_capacitableY_calibbias_calibration What: /sys/.../iio:deviceX/in_capacitableY_calibscale_calibration KernelVersion: 6.1 Contact: linux-iio@vger.kernel.org Description: Write 1 to trigger a calibration of the calibbias or calibscale. For calibscale, a full scale capacitance should be connected to the capacitance input and a calibscale_calibration then started. For calibbias see the device datasheet section on "capacitive system offset calibration".
