With wiring like this:(CLK - GPIO 0; DT - GPIO 1; GND - GND; + - 3.3 V; SW not connected)
and my Raspberry Pi Pico attached on /dev/ttyACM1 (yours will likely be on /dev/ttyACM0), I installed the encoder library like this (don't type the $):Then I ran the following code, which I think is practically identical to the OPs:It ran without problems, printing a new value every time I turned the encoder.
If you don't have mpremote installed, you can get it with (again, don't type the $s):
