Help Required on Getting Homebrew EmonPi Running

[Gwil]

Could be a problem encountered in another recent thread: the
new Arduino IDE requires a declaration of showString( ) in the main sketch.

Arduino IDE problem - showString( )

All it needs is a declaration of showString, in the main file: static void showString (PGM_P s); I usually insert those just above the first executable statement, viz: OneWire oneWire(W1PIN); static void showString (PGM_P s); void setup() { ... etc Now why does this version need it, and V1.8.1 didn’t, and why does it not need definitions of all the other functions in the supporting files? Methinks it’s a bug. In previous versions, the definition sufficed.
