Discrete set of available values for the respective counter configuration are listed in this file. What: /sys/bus/iio/devices/iio:deviceX/in_countY_count_mode KernelVersion: 4.10 Contact: linux-iio@vger.kernel.org Description: This interface is deprecated; please use the Counter subsystem. Count mode for channel Y. Four count modes are available: normal, range limit, non-recycle, and modulo-n. The preset value for channel Y is used by the count mode where required. Normal: Counting is continuous in either direction. Range Limit: An upper or lower limit is set, mimicking limit switches in the mechanical counterpart. The upper limit is set to the preset value, while the lower limit is set to 0. The counter freezes at count = preset when counting up, and at count = 0 when counting down. At either of these limits, the counting is resumed only when the count direction is reversed. Non-recycle: Counter is disabled whenever a 24-bit count overflow or underflow takes place. The counter is re-enabled when a new count value is loaded to the counter via a preset operation or write to raw. Modulo-N: A count boundary is set between 0 and the preset value. The counter is reset to 0 at count = preset when counting up, while the counter is set to the preset value at count = 0 when counting down; the counter does not freeze at the bundary points, but counts continuously throughout. What: /sys/bus/iio/devices/iio:deviceX/in_countY_noise_error KernelVersion: 4.10 Contact: linux-iio@vger.kernel.org Description: This interface is deprecated; please use the Counter subsystem. Read-only attribute that indicates whether excessive noise is present at the channel Y count inputs in quadrature clock mode; irrelevant in non-quadrature clock mode. What: /sys/bus/iio/devices/iio:deviceX/in_countY_preset KernelVersion: 4.10 Contact: linux-iio@vger.kernel.org Description: This interface is deprecated; please use the Counter subsystem. If the counter device supports preset registers, the preset count for channel Y is provided by this attribute. What: /sys/bus/iio/devices/iio:deviceX/in_countY_quadrature_mode KernelVersion: 4.10 Contact: linux-iio@vger.kernel.org Description: This interface is deprecated; please use the Counter subsystem. Configure channel Y counter for non-quadrature or quadrature clock mode. Selecting non-quadrature clock mode will disable synchronous load mode. In quadrature clock mode, the channel Y scale attribute selects the encoder phase division (scale of 1 selects full-cycle, scale of 0.5 selects half-cycle, scale of 0.25 selects quarter-cycle) processed by the channel Y counter. Non-quadrature: The filter and decoder circuit are bypassed. Encoder A input serves as the count input and B as the UP/DOWN direction control input, with B = 1 selecting UP Count mode and B = 0 selecting Down Count mode. Quadrature: Encoder A and B inputs are digitally filtered and decoded for UP/DN clock.

Whether to set channel Y counter with channel Y preset value when channel Y index input is active, or continuously count. Valid attribute values are boolean. What: /sys/bus/iio/devices/iio:deviceX/in_indexY_index_polarity KernelVersion: 4.10 Contact: linux-iio@vger.kernel.org Description: This interface is deprecated; please use the Counter subsystem. Active level of channel Y index input; irrelevant in non-synchronous load mode. What: /sys/bus/iio/devices/iio:deviceX/in_indexY_synchronous_mode KernelVersion: 4.10 Contact: linux-iio@vger.kernel.org Description: This interface is deprecated; please use the Counter subsystem. Configure channel Y counter for non-synchronous or synchronous load mode. Synchronous load mode cannot be selected in non-quadrature clock mode. Non-synchronous: A logic low level is the active level at this index input. The index function (as enabled via set_to_preset_on_index) 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 set_to_preset_on_index) is performed synchronously with the quadrature clock on the active level of the index input.
