The QR lib I used defines a macro with the same name.
The author of that should probably have an if defined check but this only produces a warning.

I learned something from you about compiling code with same names in VSCode and PlatformIO.

Maybe others don't care about "program warnings", but I worked within a large group (5-10) of programmers,. Some were of the type - the compiler will find my errors - I was one who spent the time to "fix before found" and was known to create "tight" code - using register to register instructions (much faster than memory to register instructions. SSome of my code is still running after 50 years!!!!
