JoKer 0:f76850de7b57 5 Inheritance is one of the great features of object oriented languages like C++. The stream methods are not included in serial to allow you to use them in other classes as well. They are for example also included in the TextLCD class and in my enhanced TextLCD class. All you need to do to make use of the powerful printf features is implement a putc() method in your own new class.
