quadrature_encoder

Struct QuadStep

Source 
pub struct QuadStep;
Expand description

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.

Quad-step mode effectively quadruples the resolution of the decoder.

Quad-step mode provides:

  • low noise-resistance (factor 1× relative to naïve decoding)
  • high resolution (factor 1× relative to native resolution)

Trait Implementations§

Source§

impl StepMode for QuadStep

Source§

const PULSES_PER_CYCLE: usize = 4usize

The number of pulses per (quadrature) cycle (PPC).

As an example, consider the effective pulses per revolution (PPR) of a rotary encoder with 100 cycles per revolution (CPR): 400 PPR.
