Crate quadrature_encoder

An efficient no_std-compatible implementation of a quadrature encoder driver, based on a finite-state-transducer with support for different step-modes.

Structs

Async

Driver initialized in async mode.

Blocking

Driver initialized in blocking mode.

FullStep

A step mode that is able to detect a “change” (e.g. movement) for every stable full cycle (i.e. 1 change per quadrature cycle).

HalfStep

A step mode that is able to detect a “change” (e.g. movement) (e.g. movement) for every stable half cycle (i.e. 2 changes per quadrature cycle), resulting in an effective 2× resolution multiplication.

IncrementalEncoder

A robust incremental encoder with support for multiple step-modes.

IndexedIncrementalEncoder

A robust incremental encoder with support for multiple step-modes.

Linear

The mode of a linear quadrature encoder.

QuadStep

A step mode that is able to detect a “change” (e.g. movement) for every stable quarter cycle (i.e. 4 change per quadrature cycle), resulting in an effective 4× resolution multiplication.

Rotary

The mode of a rotary quadrature encoder.

Enums

Error

An error indicating quadrature or input pin issues.

InputPinError

An error indicating an input pin issue.

LinearMovement

The movement detected by a linear quadrature encoder.

QuadratureError

An error indicating an invalid quadrature signal sequence.

RotaryMovement

The movement detected by a rotary quadrature encoder.

Traits

OperationMode

The mode of physical operation of a quadrature encoder.

PollMode

A marker trait for initializing drivers in a specific mode. Inspired by https://github.com/esp-rs/esp-hal
