Raspberry pi pico RP2040 Not supported

[RichieUnpar]

Description

i want to use this library using the rp2040 board but it seems the library does not directly support the raspberry pi version but it does support the Arduino Nano Rp2040 Connect. After adding the rp2040 board to the interrupt_pins.h with my text being:

//RP2040 Connect https://arduino-pico.readthedocs.io/en/latest/contrib.html#adding-a-new-board

Steps To Reproduce Problem

upload any program that has the #include <Encoder.h> in the code
this problem persist whethever #define ENCODER_DO_NOT_USE_INTERRUPTS is used or not

Hardware & Software

Board
Generic RP2040/ Raspberry pi pico rp2040 board

Arduino Sketch

Any Example library will reproduce the problem, just include the #include <Encoder.h>

Error compiling for board Generic RP2040.

Did you ever find a way to fix this?

[MrPatben8]

There is still no support for the Pico. Maybe it's because the Pico 2 uses the RP2350 which is not explicitly supported instead of the RP2040

[doctea]

I forget the details, so this shouldn't be considered a complete fix; but I use this fork successfully with my RP2040 project (along with initialising at runtime instead of statically, as discussed in #85): https://github.com/doctea/Encoder. Hope it helps someone out
