I’m getting nowhere.
How do I stop the compile using a “previously compiled library” ?
I have changed the DCC_Decoder.cpp file but I don’t know whether it is using the modified version.
N.B I have accumulated several (7) copies of DCC_Decoder.cpp & DCC_Decoder.h files over the years, in various Arduino folders, as well as three each of the .o &.d appended versions.
