Adding classes?

Post by Kronsson »

Hi,

Is it possible to add user defined classes?
I've tried with very basic examples that works with "Arduino classic" but cannot get the Z-UNO compiler to accept it.

One of the classes I want use is the attached elapsedMillis.h
Reference:
http://playground.arduino.cc/Code/ElapsedMillis

Could someone show how to successfully use this it would be very appreciated.

Code: Select all

You have to place it in the same folder as the Z-Uno libs are.

The lib loos pretty ok, but not sure Z-Uno compiler do support operators redefinition. Need to ask developers.
