- What: /sys/bus/iio/devices/iio:deviceX/ac_excitation_en
- KernelVersion:
- Contact: [email protected]
- Description:
- This attribute, if available, is used to enable the AC
- excitation mode found on some converters. In ac excitation mode,
- the polarity of the excitation voltage is reversed on
- alternate cycles, to eliminate DC errors.
- What: /sys/bus/iio/devices/iio:deviceX/bridge_switch_en
- KernelVersion:
- Contact: [email protected]
- Description:
- This attribute, if available, is used to close or open the
- bridge power down switch found on some converters.
- In bridge applications, such as strain gauges and load cells,
- the bridge itself consumes the majority of the current in the
- system. To minimize the current consumption of the system,
- the bridge can be disconnected (when it is not being used
- using the bridge_switch_en attribute.
- What: /sys/bus/iio/devices/iio:deviceX/in_voltagex_sys_calibration
- KernelVersion:
- Contact: [email protected]
- Description:
- Initiates the system calibration procedure. This is done on a
- single channel at a time. Write '1' to start the calibration.
- What: /sys/bus/iio/devices/iio:deviceX/in_voltage2-voltage2_shorted_raw
- KernelVersion:
- Contact: [email protected]
- Description:
- Measure voltage from AIN2 pin connected to AIN(+)
- and AIN(-) shorted.
- What: /sys/bus/iio/devices/iio:deviceX/in_voltagex_sys_calibration_mode_available
- KernelVersion:
- Contact: [email protected]
- Description:
- Reading returns a list with the possible calibration modes.
- There are two available options:
- "zero_scale" - calibrate to zero scale
- "full_scale" - calibrate to full scale
- What: /sys/bus/iio/devices/iio:deviceX/in_voltagex_sys_calibration_mode
- KernelVersion:
- Contact: [email protected]
- Description:
- Sets up the calibration mode used in the system calibration
- procedure. Reading returns the current calibration mode.
- Writing sets the system calibration mode.
