Frequencies.ino errors

[bncdemo]

It is not possible to compile frequencies.ino

The error message:

Could you provide more information? It compiles just fine for me on Arduino IDE v2.1.1-nightly-20230502

[bncdemo]

I had to remove the aurdinoFTT library, then download and manually install the arduinoFFT-develop source. With that everything is ok. Is there a way to contact you? /related to this project but not to this topic/

[sheaivey]

Oh right! The module is using the ArduinoFFT develop version which is faster and has a lot more features. I believe that is called out in the readme but it could probably be more prominent. Known Issues

I wish they would just publish the develop branch under a new project.
