Rotary encoders are great devices. Monitoring just a few pins you can easily and quickly read in rotation and direction of a user input (as well as many other applications). But as with anything, ...

Rotary encoders are pretty interesting pieces of technology. They’re a solid way to accurately measure rotation including the direction. [David] recently wrote some software to handle these input ...

Encoders and decoders are common elements in alarm, remote-control, and measurement systems. However, most of these devices require many I/O lines when under microprocessor or PC control. For example, ...

Datacard Group announced Monday the launch of its SuperCAT II card encoder, which allows bank customers to select or change a card's PIN at a branch. The vendor's card-encoding device works with its ...

“I looked at all the available rotary encoder sketches and none of them met my needs, so I have written my own, and here it is”. Well, I looked at all the available rotary encoder sketches and none of ...

In this Design Idea, an old technique of diode-based 16-to-4 encoding is combined with a new design, to scan a record number of buttons – 74 – with only four I/O pins! First start with the ancient ...

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...

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 ...

When an automation system which includes an encoder must be certified to a specific Performance Level (PL) or Safety Integrity Level (SIL), the design of its safety system must consider both ...
