feasibility of using Teen 3.x with 3 quadrature encoders?

[hrh1818]

A person wants to use 3 quadrature encoders for volume controls and display the number of counts. As far as I Know you can only use one quadrature encoder at a time when the encoder is directly connected to a ARduino Uno board. Hence would it possible to use 3 directly coupled quadrature encoders with Teensy 3.0 or 3.1?

If not would it be possible to use 3 quadrature encoders with Teensy 3.0 or 3.1 if a converter like a LS7184 is used? A LS7184 converts the output of a quadrature encoder to a clock pulse and a direction signal. See:

Yes, 3 encoders works well. Just use the Encoder library.

On Arduino Uno, only 2 pins have interrupt capability.

On Teensy 3.1, all 34 digital pins can be used as interrupts!

Thanks Paul,

Perfect Answer.
