Compatibility with Arduino boards

[vzahradnik]

Library is not compatible with most common boards. We get compile or dependency errors.

Same with Teensy. Fails to build when included as a dependency in my PlatformIO project.

I use this exclusively on ESP32. Adding more boards is easy but I don't want to spend too much time with it. If you have a board which doesn't work properly, raise an issue and ideally provide your board config from platformio.ini. Then we will add it as another build target and fix the failures.
