This
blog post is the first in series (hopefully, there will be more) of
tutorials on the EvoPrimer dev kit from Raisonance. These tutorials
will mainly concentrate on usage of the circle OS. This tutorial
assumes that you already know how to create a simple Circle OS
project. If you are not aware of the procedure to do so, you can
follow this tutorial to learn about it.
For
this tutorial, we will see how we can create and use a tool bar under
Circle OS. Toolbars are the widgets that appear on the top of the
LCD.
For
this tutorial, we will build a simple game of gears, papers and
scissors (I could not find a rock icon in Tango image library :p).
The game logic itself is simple, the CPU makes a random selection of
an object, either a rock(gears), paper or scissor and compares
against the user selection, selected via the tool bar.
