This paper introduces the huge range of free and open source software available to the embedded software developer. Hardware modeling, software tool chains, operating systems (RTOS and Linux), middleware and applications are all covered. Today open source is spreading to the hardware world. The paper addresses the advantages and risks associated with using free and open source software, including the issues of quality, support and licensing.


Arduino Microcontroller Guide

The Arduino microcontroller is an easy to use yet powerful single board computer that has gained considerable traction in the hobby and professional market. The Arduino is open-source, which means hardware is reasonably priced and development software is free. This guide is for students in ME 2011, or students anywhere who are confronting the Arduino for the first time. For advanced Arduino users, prowl the web; there are lots of resources.

The purpose of this book is to get you started on the road to creating things using micro-controllers. We will discuss only enough electronics for you to make the circuits, and only enough programming for you to get started. The focus will be on your making things. It is my hope that as you go through this book you will be flooded with ideas of things that you can make.


Real-time Image Processing on Low Cost Embedded Computers

In 2012 a federal mandate was imposed that required the FAA to integrate unmanned aerial systems (UAS) into the national airspace (NAS) by 2015 for civilian and commercial use. A significant driver for the increasing popularity of these systems is the rise in open hardware and open software solutions which allow hobbyists to build small UAS at low cost and without specialist equipment. This paper describes our work building, evaluating and improving performance of a vision-based system running on an embedded computer onboard such a small UAS. This system utilises open source software and open hardware to automatically land a multi-rotor UAS with high accuracy. Using parallel computing techniques, our final implementation runs at the maximum possible rate of 30 frames per second. This demonstrates a valid approach for implementing other real-time vision based systems onboard UAS using low power, small and economical embedded computers.


Guide to designing a device incorporating MEMS-based pico projection

Carlos Lopez

Over the last few years, millions of products incorporating pico projection have shipped, and developers are innovating new applications for this rapidly growing display category. Ideal applications for pico projection include near eye display, interactive digital signage, head mounted display, ultra short throw (UST) TV, standalone portable projectors and embedded projection in smartphones, tablets and laptops. New uses continue to emerge; for example, you might be able imagine a design for a thermostat using a display powered by gesture recognition or interactive touch.

This tutorial provides information on the tool and the basic steps for programming the Atmel AVR microcontrollers using C. It is aimed at people who are new to this family of microcontrollers. The Atmel STK500 development board and the ATmega16 chip are used in this tutorial; however, it is easy to adopt the information given here for other AVR chips.

If you haven’t done it so far then it’s high time to learn what the microcontrollers are and how they operate. Numerous illustrations and practical examples along with detailed description of the PIC16F887 will make you enjoy your work with the PIC microcontrollers


Introduction to Microcontrollers

This text has been developed for the introductory courses on microcontrollers taught by the Institute of Computer Engineering at the Vienna University of Technology. It introduces undergraduate students to the field of microcontrollers – what they are, how they work, how they interface with their I/O components, and what considerations the programmer has to observe in hardware-based and embedded programming. This text is not intended to teach one particular controller architecture in depth, but should rather give an impression of the many possible architectures and solutions one can come across in today’s microcontrollers. We concentrate, however, on small 8-bit controllers and their most basic features, since they already offer enough variety to achieve our goals.

Section 1 describes the main characteristics that a real-time operating system should have.
Section 2 discusses the scope of some of the more well known RTOSs.
Section 3 introduces the languages used for real-time programming and compares the main characteristics.
Section 4 presents and compares different alternatives for the implementation of real-time Java.
