Libraries python for encoder

[herter]

Hello,

I have to acquire some datas from incremental encoders and I would like know if there is some libraries or examples in python with the GPIOs of the A20.
Thank you,
Regards.

I already know and use this one, but I just want to know if someone or examples can manage the signals from incremental encoder.
