I want to use this RF22 module (in a breakout board) with a Raspberry Pi Pico. However, I have tried both the RadioHead (which is for teensy boards, as i found out later) and RF22 library without any success. The code cannot be compiled for Raspberry Pi Pico. Do you have any other libraries to suggest that I could use?
This is a working library: https://www.airspayce.com/mikem/arduino/RadioHead/
I had the modified library installed that is compatible with Teensy boards.
