Coding - Getting started | "Hello World"
Update #10122  |  04 Nov 2014
 

This part describe the steps followed to be able to start coding our application. It's important to highlight that the development platform is Windows.

Toradex Developer Center offer several guides, tutorials and how-to in order to help you out to develop you application. All the information provide here, is totally based on their information.

Colibri T20 - Hardware description and interaction

Globodaq is based on the computer module Colibri T20 from Toradex AG, in order to provide the peripherals capability is used the carrier board Iris. For their description please follow this links.

Unpacking:  Toradex AG provide an unpacking tutorial, please follow it here.

Next, is necessary to define the setup environment. As is described in the Colibri T20 tutorial, there is either the possibility to use a monitor with VGA cable, keyboard and mouse, or use a Remote Desktop (Windows) application to interact with the Colibri T20.

It is relevant to mention that more ways to perform the interaction. But, for our case we have chosen the option of Remote Desktop application. Because, as was mention in the second update, it has been selected Windows Compact Embedded 7 as the O.S. for our project. For more details please watch the video below.

 

Flashing O.S image on the Colibri T20

The computer module Colibri T20 comes out of the box with Windows Embedded preloaded. However, to perform this primary task, a very well explain video tutorial by Toradex AG was followed, to visit it here

We flash Linux at the beginning, and start developing the application on it. But, as is explain in the second update, finally we have chosen Windows Compact Embedded 7.

It is important to highlight the boot speed of the our Colibri T20, as Toradex AG claims, is half a second!!!!

 

Setting up Development Environment

In order to start to develop our application, is necessary to set up the development environment. The main steps that were follow for this project are listed below, in case of any need of more information please refer to Toradex Developer Center WEBSITE.

Download the required software (Please follow the links):

  1. Windows Mobile Center  ---> Toradex Link Support
  2. Visual Studio 2008:  Microsoft DreamSpark (Students) ---> Toradex Link Support
  3. Windows Embedded Compact 7 updates for Visual Studio 2008: Link1  Link2  ---> Toradex Link Support
  4. Windows Embedded Compact 7 SDK ---> Toradex Link Support
  5. Remote Display tool --> Toradex Link Support

 

“Hello World”

Once all the installations are done, we can proceed with the creation of a project in Visual Studio. First, is necessary to choose the programing language that it will be used, for now we will be using C++.

The video below described all the steps followed.
