Compilation Problems

[Oye-Hamzay56]

When i'm trying to compile the detect example for the above library, arduino IDE gives out the following errors:
`

`
Any solution for such errors?

I know this is an old comment by now, but the issue is that in some cases the _N macro is already defined (e.g., I'm using this on a Teensy 4.0, and _N is a bad choice). By renaming _N to _NSZ, I'm able to get the code to compile.
