How it would be possible to use this library with a rotary Encoder

I am using an ESP32 and running out of pins. This library has been very useful and simple to use with push buttons but I am having a lot of trouble trying to make rotary encoder to work.

any suggestion or idea would be h.a.

SPI is pretty fast, it would depend on your polling rate if you are not using interrupts for the pins. Interrupt would be better especially if your loop has slow code if you wanna catch the encoder signals.
