What: /sys/bus/iio/devices/iio:deviceX/in_voltageY_sensing_mode Date: August 2015 KernelVersion: 4.2.0 Contact: source@cogentembedded.com Description: Program sensor type for threshold detector inputs. Could be either "GND-Open" or "Supply-Open" mode. Y is a threshold detector input channel. Channels 0..7, 8..15, 16..23 and 24..31 has common sensor types. What: /sys/bus/iio/devices/iio:deviceX/events/in_voltageY_thresh_falling_value Date: August 2015 KernelVersion: 4.2.0 Contact: source@cogentembedded.com Description: Channel Y low voltage threshold. If sensor input voltage goes lower then this value then the threshold falling event is pushed. Depending on in_voltageY_sensing_mode the low voltage threshold is separately set for "GND-Open" and "Supply-Open" modes. Channels 0..31 have common low threshold values, but could have different sensing_modes. The low voltage threshold range is between 2..21V. Hysteresis between low and high thresholds can not be lower then 2 and can not be odd. If falling threshold results hysteresis to odd value then rising threshold is automatically subtracted by one. What: /sys/bus/iio/devices/iio:deviceX/events/in_voltageY_thresh_rising_value Date: August 2015 KernelVersion: 4.2.0 Contact: source@cogentembedded.com Description: Channel Y high voltage threshold. If sensor input voltage goes higher then this value then the threshold rising event is pushed. Depending on in_voltageY_sensing_mode the high voltage threshold is separately set for "GND-Open" and "Supply-Open" modes. Channels 0..31 have common high threshold values, but could have different sensing_modes. The high voltage threshold range is between 3..22V. Hysteresis between low and high thresholds can not be lower then 2 and can not be odd. If rising threshold results hysteresis to odd value then falling threshold is automatically appended by one.
