NI myRIO: Rotary (quadrature) encoder

The rotary encoder, or quadrature encoder, combines a rotary knob and two switches that open and close in a staggered fashion as the knob turns. With suitable decoding of the switching waveforms the knob angle and rotation direction can be sensed. Learn the rotary encoder principles of operation, interfacing techniques for the MXP and MSP connectors, and necessary circuitry to debounce the switches.
