Error compiling - missing "min"

[gioreva]

1. Not Compile. See abore errors.
2. Can I have one example of costructor, hardware serial and no reset connectet ?

Arduino:1.7.11 (Windows 7), Scheda:"Arduino M0"

[Per Cederberg]

What kind of environment are you compiling in? The min function is part of the Arduino "language reference", so it should be available in all compatible environments. See https://www.arduino.cc/en/Reference/Min
