  1. What: /sys/bus/iio/devices/iio:deviceX/in_voltageY_sensing_mode

  5. Description:
  6. Program sensor type for threshold detector inputs.
  7. Could be either "GND-Open" or "Supply-Open" mode. Y is a
  8. threshold detector input channel. Channels 0..7, 8..15, 16..23
  9. and 24..31 has common sensor types.

  14. Description:
  15. Channel Y low voltage threshold. If sensor input voltage goes lower then
  16. this value then the threshold falling event is pushed.
  17. Depending on in_voltageY_sensing_mode the low voltage threshold
  18. is separately set for "GND-Open" and "Supply-Open" modes.
  19. Channels 0..31 have common low threshold values, but could have different
  20. sensing_modes.
  21. The low voltage threshold range is between 2..21V.
  22. Hysteresis between low and high thresholds can not be lower then 2 and
  23. can not be odd.
  24. If falling threshold results hysteresis to odd value then rising
  25. threshold is automatically subtracted by one.

  30. Description:
  31. Channel Y high voltage threshold. If sensor input voltage goes higher then
  32. this value then the threshold rising event is pushed.
  33. Depending on in_voltageY_sensing_mode the high voltage threshold
  34. is separately set for "GND-Open" and "Supply-Open" modes.
  35. Channels 0..31 have common high threshold values, but could have different
  36. sensing_modes.
  37. The high voltage threshold range is between 3..22V.
  38. Hysteresis between low and high thresholds can not be lower then 2 and
  39. can not be odd.
  40. If rising threshold results hysteresis to odd value then falling
  41. threshold is automatically appended by one.
