- 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.

- 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.

- 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.
