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.

|
Description:
|
|
Whether detection of differential encoder cable faults for the
|
|
respective channel of Signal Y is enabled. Valid attribute
|

|
|
Description:
|
|
Filter clock factor for input Signal Y. This prescaler value
|
|
affects the inputs of both quadrature pair signals.

Description:
|
|
Active level of index input Signal Y; irrelevant in

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.
