The LS7366R IC performs decoding and counting of quadrature clocks directly ... line rate (at 5 V) from the encoder and a count limit of 232. A serial interface (SPI) greatly reduces the required ...

Quadrature parts count only on the rising edge of the A input – so pick your encoder with this in mind. Counting in LS7193 and LS7194 is enabled all the time, while the other devices have an ...

As a very nice touchy-feely user interface, Anders has sourced a range of chunky rotary knob quadrature encoders that have a circular colour display in the middle – hundreds of pixels across. The ...
