Y is a 8 threshold detector input channel. Channels 0..7, 8..15, 16..23 9 and 24..31 has common sensor types. 10 11What: /sys/bus/iio/devices/iio:deviceX/events/in_voltageY_thresh_falling_value 12Date: August 2015 13KernelVersion: 4.2.0 14Contact: source@cogentembedded.com 15Description: 16 Channel Y low voltage threshold. If sensor input voltage goes lower then 17 this value then the threshold falling event is pushed. 18 Depending on in_voltageY_sensing_mode the low voltage threshold 19 is separately set for "GND-Open" and "Supply-Open" modes. 20 Channels 0..31 have common low threshold values, but could have different 21 sensing_modes. 22 23 The low voltage threshold range is between 2..21V. 24 Hysteresis between low and high thresholds can not be lower then 2 and 25 can not be odd. 26 27 If falling threshold results hysteresis to odd value then rising 28 threshold is automatically subtracted by one. 29 30What: /sys/bus/iio/devices/iio:deviceX/events/in_voltageY_thresh_rising_value 31Date: August 2015 32KernelVersion: 4.2.0 33Contact: source@cogentembedded.com 34Description: 35 Channel Y high voltage threshold. If sensor input voltage goes higher then 36 this value then the threshold rising event is pushed. 37 Depending on in_voltageY_sensing_mode the high voltage threshold 38 is separately set for "GND-Open" and "Supply-Open" modes. 39 40 Channels 0..31 have common high threshold values, but could have different 41 sensing_modes. 42 43 The high voltage threshold range is between 3..22V. 44 Hysteresis between low and high thresholds can not be lower then 2 and 45 can not be odd. 46 47 If rising threshold results hysteresis to odd value then falling 48 threshold is automatically appended by one. 49
