Circle OS tutorial: Menu

In this tutorial, we are going to learn how one can use menu GUI element available in the circle OS. For this tutorial,we are going to implement a simple game, wherein you are presented a random math question and the list of options(you guessed it right, the list of options are actually implemented using the menus) one among them is the right answer. Once an option is selected, you are notified whether the choice was right or wrong. As was the case with the previous tutorial, I am going to explain about the game logic and then move on to circle OS menu usage details.

EvoPrimer Tutorial: ToolBars

 

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.
