Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

Computer mice existed long before the Mac, and most of the old 8-bit computers had some software that could use a mouse. These mice had balls and quadrature encoders. While converters to turn these ...

The sensing mechanism in an incremental optical rotary encoder consists primarily of a light source, code wheel, and optical detector. As the code wheel turns, a ring of alternating opaque and ...

The LS7566 24-bit four-axis quadrature counter provides an efficient interface for up to four incremental encoders. The encoder inputs are digitally filtered for elimination of noise and errors ...

LSI Computer Systems (LSI/CSI) has created a family of 63 tap (6bit) digital potentiometers for direct connection to quadrature decoders, push buttons, GPIOs or SPI serial controls. Debounce circuits ...

Everyone has at least one extra mouse laying around; why not get some use out of it? Disassembling the mouse you can get two optical encoders plus four infrared emitter/detector pairs. Then you can ...

Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...

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 ...

If you are a novice to rotary encoders for human-machine interface, there is a potential pit-fall. Otherwise called quadrature encoders, they deliver two-bit gray-scale binary on rotation, with the ...
