#define INPUT_PULLUP /Arduino Due

[Der-Modellmann]

If I #define INPUT_PULLUP an error occure.

Arduino: 1.8.2 (Windows 10), Board: "Arduino Due (Programming Port)"

exit status 1 Fehler beim Kompilieren für das Board Arduino Due (Programming Port).

Dieser Bericht wäre detaillierter, wenn die Option "Ausführliche Ausgabe während der Kompilierung" in Datei -> Voreinstellungen aktiviert wäre.

Is this my fault or an error in that library ?

Thanks Gabriel

INPUT_PULLUP is a #define normally "invisibly" included in arduino to allow you to code the pinMode with something recognizable like : pinMode(EncoderPinA, INPUT_PULLUP); Re defining it causes issues with the compiler.

Yes, you're correct. This is an old, invalid issue. Closing it now.
