1What: /sys/bus/iio/devices/iio:deviceX/ac_excitation_en 2KernelVersion: 3Contact: linux-iio@vger.kernel.org 4Description: 5 Reading gives the state of AC excitation. 6 Writing '1' enables AC excitation. 7 8What: /sys/bus/iio/devices/iio:deviceX/bridge_switch_en 9KernelVersion: 10Contact: linux-iio@vger.kernel.org 11Description: 12 This bridge switch is used to disconnect it when there is a 13 need to minimize the system current consumption. 14 Reading gives the state of the bridge switch. 15 Writing '1' enables the bridge switch. 16 17What: /sys/bus/iio/devices/iio:deviceX/in_voltagex_sys_calibration 18KernelVersion: 19Contact: linux-iio@vger.kernel.org 20Description: 21 Initiates the system calibration procedure. This is done on a 22 single channel at a time. Write '1' to start the calibration. 23 24What: /sys/bus/iio/devices/iio:deviceX/in_voltagex_sys_calibration_mode_available 25KernelVersion: 26Contact: linux-iio@vger.kernel.org 27Description: 28 Reading returns a list with the possible calibration modes. 29 There are two available options: 30 "zero_scale" - calibrate to zero scale 31 "full_scale" - calibrate to full scale 32 33What: /sys/bus/iio/devices/iio:deviceX/in_voltagex_sys_calibration_mode 34KernelVersion: 35Contact: linux-iio@vger.kernel.org 36Description: 37 Sets up the calibration mode used in the system calibration 38 procedure. Reading returns the current calibration mode. 39 Writing sets the system calibration mode. 40
