Guide to designing a device incorporating MEMSbased pico projection
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.
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.

Getting Started with C Programming for the ATMEL AVR Microcontrollers
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.
PIC Microcontrollers - Programming in C
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
Microcontroller Programming and Interfacing
Chapter 7 of the book: Introduction to Mechatronics and Measurement Systems
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.
Real-Time Operating Systems and Programming Languages for Embedded Systems
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.
Software Development for Parallel and Multi-Core Processing
The embedded software industry wants microprocessors with increased computing functionality that maintains or reduces space, weight, and power (SWaP). Single core processors were the key embedded industry solution between 1980 and 2000 when large performance increases were being achieved on a yearly basis and were fulfilling the prophecy of Moore's Law. Moore's Law states that "the number of transistors that can be placed inexpensively on an integrated circuit doubles approximately every two years." With the increased transistors, came microprocessors with greater computing throughput while space, weight and power were decreasing. However, this 'free lunch' did not last forever. The additional power required for greater performance improvements became too great starting in 2000. Hence, single core microprocessors are no longer an optimal solution.
First Steps with Embedded Systems
This book is intended to fill the need for an intermediate level overview of programming microcontrollers using the C programming language. It is aimed specifically at two groups of readers who have different, yet overlapping needs. The first group are familiar with C but require an examination of the general nature of microcontrollers: what they are, how they behave and how best to use the C language to program them. The second group are familiar with microcontrollers but are new to the C programming language and wish to use C for microcontroller development projects. First Steps with Embedded Systems will be useful both as an introduction to microcontroller programming for intermediate level post-secondary programs and as a guide for developers coping with the growth and change of the microcontroller industry.
Interface Protection for HDMI
The High-Definition Multimedia Interface (HDMI) combines a high-speed unidirectional TMDS data link with low speed, bidirectional control and status links (DDC and CEC) and configuration protocols in a single user-friendly highperformance connector.
What’s a Multicore Microcontroller?

Introduction to Arduino
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.

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.

Essential Linux Device Drivers
This book is about writing Linux device drivers. It covers the design and development of major device classes supported by the kernel, including those I missed during my Linux-on-Watch days. The discussion of each driver family starts by looking at the corresponding technology, moves on to develop a practical example, and ends by looking at relevant kernel source files. Before foraying into the world of device drivers, however, this book introduces you to the kernel and discusses the important features of 2.6 Linux, emphasizing those portions that are of special interest to device driver writers.
Design and Implementation of the lwIP Stack
LwIP is an implementation of the TCP/IP protocol stack. The focus of the lwIP stack is to reduce memory usage and code size, making lwIP suitable for use in small clients with very limited resources such as embedded systems. In order to reduce processing and memory demands, lwIP uses a tailor made API that does not require any data copying. This report describes the design and implementation of lwIP. The algorithms and data struc- tures used both in the protocol implementations and in the sub systems such as the memory and bu®er management systems are described. Also included in this report is a reference manual for the lwIP API and some code examples of using lwIP.
