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 ...

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 ...

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 counter project was created to read one or two digital or analog sensors and display the running total on an organic LED display. The speed of an attached DC motor can be controlled by the counter ...

I wrote a bit of VHDL for generating inc/dec pulses from quadrature rotary encoders like the CTS Electrocomponents ones I bought from Digikey for a project I worked on recently. This debounce circuit ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.

Shaft motion can be tracked by incremental encoders for analysis and use by system controls downstream. Rotational direction is monitored with an encoder Shaft motion can be tracked by incremental ...
