- What: /sys/bus/counter/devices/counterX/signalY/cable_fault
- KernelVersion: 5.7
- Contact: linux-iio@vger.kernel.org
- Description:
- Read-only attribute that indicates whether a differential
- encoder cable fault (not connected or loose wires) is detected
- for the respective channel of Signal Y. Valid attribute values
- are boolean. Detection must first be enabled via the
- corresponding cable_fault_enable attribute.
- What: /sys/bus/counter/devices/counterX/signalY/cable_fault_enable
- KernelVersion: 5.7
- Contact: linux-iio@vger.kernel.org
- Description:
- Whether detection of differential encoder cable faults for the
- respective channel of Signal Y is enabled. Valid attribute
- values are boolean.
- What: /sys/bus/counter/devices/counterX/signalY/filter_clock_prescaler
- KernelVersion: 5.7
- Contact: linux-iio@vger.kernel.org
- Description:
- Filter clock factor for input Signal Y. This prescaler value
- affects the inputs of both quadrature pair signals.
- What: /sys/bus/counter/devices/counterX/signalY/index_polarity
- KernelVersion: 5.2
- Contact: linux-iio@vger.kernel.org
- Description:
- Active level of index input Signal Y; irrelevant in
- non-synchronous load mode.
- What: /sys/bus/counter/devices/counterX/signalY/index_polarity_available
- What: /sys/bus/counter/devices/counterX/signalY/synchronous_mode_available
- KernelVersion: 5.2
- Contact: linux-iio@vger.kernel.org
- Description:
- Discrete set of available values for the respective Signal Y
- configuration are listed in this file.
- What: /sys/bus/counter/devices/counterX/signalY/synchronous_mode
- KernelVersion: 5.2
- Contact: linux-iio@vger.kernel.org
- Description:
- Configure the counter associated with Signal Y for
- non-synchronous or synchronous load mode. Synchronous load mode
- cannot be selected in non-quadrature (Pulse-Direction) clock
- mode.
- non-synchronous:
- A logic low level is the active level at this index
- input. The index function (as enabled via preset_enable)
- is performed directly on the active level of the index
- input.
- synchronous:
- Intended for interfacing with encoder Index output in
- quadrature clock mode. The active level is configured
- via index_polarity. The index function (as enabled via
- preset_enable) is performed synchronously with the
- quadrature clock on the active level of the index input.
