I'm trying to get the d1 mini to work with this, since the guide mentioned it could be done with minor modifications. I'm only getting a lot of compilation errors and I haven't got much succes with it.
Well, yes, I think you are right. At the time of writing the guide, the code was not as ESP32 specific as it is now.
I suggest you give the ESP32 a try.
