My previous blog Encoders Know All the Angles introduced encoders that provide information about rotary positions. A diagram illustrated the phase relationship of signals from an incremental encoder.

Incremental-rotation or linear encoders are very common, but normally they do not provide a direction signal. This design shows an easy way to detect forward or reverse direction. Incremental encoders ...

Special hardware can overcome software latency that may otherwise negate precise motion control. Precision motion control is virtually never an end in itself. Rather, it ties position to other events ...

• The new mantra of position encoding is low-current drain. • Capacitive encoding is a way to realize low-power consumption without giving up resolution or accuracy, even at relatively low speeds.

Quadrature encoders have many uses in position-sensing applications. This implementation uses a Xilinx complex programmable logic device (CPLD) to count the pulses from the encoder and determine the ...

The Altera® 2.5G Reed-Solomon (RS) II MegaCore® function reference design demonstrates a basic application of the Reed-Solomon algorithm in data transmission between the Altera RS II encoder and ...
