An Engineer's Guide to the LPC2100 Series
●7 commentsThis book is intended as a hands-on guide for anyone planning to use the Philips LPC2000 family of microcontrollers in a new design. It is laid out both as a reference book and as a tutorial. It is assumed that you have some experience in programming microcontrollers for embedded systems and are familiar with the C language. The bulk of technical information is spread over the first four chapters, which should be read in order if you are completely new to the LPC2000 and the ARM7 CPU.
Choosing An Ultralow-Power MCU
This application report describes how to compare ultralow-power MCUs. It discusses the key differences between popular low-power MCUs and how to interpret features and specifications and apply them to application requirements
Interrupts, Low Power Modes and Timer A
This document contains a lot of what you need to know to get the most out of the MSP430. The MSP430 line is renowned for it's low power usage, and to really utilize it well you have to architect your software to be an interrupt driven device that utilizes the low power modes.
PID Without a PhD
●7 commentsPID (proportional, integral, derivative) control is not as complicated as it sounds. Follow these simple implementation steps for quick results.
Reed-Solomon Error Correction
[Best paper on Reed-Solomon error correction I have ever read -- and it's from the BBC!] Reed-Solomon error correction has several applications in broadcasting,in particular forming part of the specification for the ETSI digital terrestrial television standard, known as DVB-T. Hardware implementations of coders and decoders for Reed-Solomon error correction are complicated and require some knowledge of the theory of Galois fields on which they are based. This note describes the underlying mathematics and the algorithms used for coding and decoding,with particular emphasis on their realisation in logic circuits. Worked examples are provided to illustrate the processes involved.
Memory allocation in C
●5 commentsThis article is about dynamic memory allocation in C in the context of embedded programming. It describes the process of dynamically allocating memory with visual aids. The article concludes with a practical data communications switch example which includes a sample code in C.
Advanced Linux Programming
●6 commentsThis book is intended for learning advanced linux programming.
Red Hat Linux - The Complete Reference
This book identifies seven major Linux topics: basic setup, environments and applications, the Internet, servers, administration, and network administration. These topics are integrated into the different ways Red Hat presents its distribution: as a desktop workstation, network workstation, server, and development platform
Essential Linux Device Drivers
●5 commentsThis 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.
CPU Memory - What Every Programmer Should Know About Memory
●6 commentsAs CPU cores become both faster and more numerous, the limiting factor for most programs is now, and will be for some time, memory access. Hardware designers have come up with ever more sophisticated memory handling and acceleration techniques–such as CPU caches–but these cannot work optimally without some help from the programmer. Unfortunately, neither the structure nor the cost of using the memory subsystem of a computer or the caches on CPUs is well understood by most programmers. This paper explains the structure of memory subsystems in use on modern commodity hardware, illustrating why CPU caches were developed, how they work, and what programs should do to achieve optimal performance by utilizing them.
Arduino Microcontroller Guide
●3 commentsThe 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.
Transforming 64-Bit Windows to Deliver Software-Only Real-Time Performance
Next-generation industrial, vision, medical and other systems seek to combine highend graphics and rich user interfaces with hard real-time performance, prioritization and precision.Today’s industrial PCs running 64-bit Windows, complemented by a separate scheduler on multicore multiprocessors, can deliver that precise real-time performance on software-defined peripherals.

Five Steps to Improving Security in Embedded Systems
In today’s increasingly interconnected world, security breaches are becoming ever more prevalent, with escalating complexity challenges. How can embedded device developers balance the need for tighter security with competing business and market demands? This paper outlines five steps for building additional security assurance into embedded devices by considering the whole product lifecycle.
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.
Software Development for Parallel and Multi-Core Processing
●1 commentThe 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.

Arduino Programming Notebook
This notebook serves as a convenient, easy to use programming reference for the command structure and basic syntax of the Arduino microcontroller. To keep it simple, certain exclusions were made that make this a beginner’s reference best used as a secondary source alongside other websites, books, workshops, or classes. This decision has lead to a slight emphasis on using the Arduino for standalone purposes and, for example, excludes the more complex uses of arrays or advanced forms of serial communication.
