Elektor Digital Design your own Embedded Linux Control Centre
This e-book (pdf) is all about building your own DIY home control system. It presents two innovative ways to assemble such a system: By recycling old PC hardware - possibly extending the life of an old PC, or by using Raspberry Pi. In both cases, the main system outlined in this e-book will consist of a computer platform, a wireless mains outlet, a controller and a USB webcam - All linked together by Linux. By using the Raspberry Pi in conjunction with Arduino (used as an advanced I/O system board), it is possible to construct a small, compact, embedded control system offering enhanced capacity for USB integration, webcams, thermal monitoring and communication with the outside world. The experience required to undertake the projects within this e-book are minimal exposure to PC hardware and software, the ability to surf the internet, burn a CD-ROM and assemble a small PCB. All custom software is available for free download (see 'attachments/downloads' section on this page).

DFRobot DFRobot Gravity - Lightning Distance Sensor
The embedded man-made disturber rejection algorithm can effectively avoid the electrical interference generated by various household appliances. In addition to allowing general weather enthusiasts to measure local thunderstorm data simply and efficiently, thanks to its compact size and wide detection range, it can also be embedded in various smart wearable devices for an outdoor climber or people who work at heights.This provides early warning of thunderstorms that people can perceive so that people can take precautions a step ahead. The sensor can also be embedded in the indoor protection device inside lightning-sensitive equipment, and automatically trigger these devices to switch to the backup power to isolate the power grid when lightning strikes. At the moment of lightning, the interrupt pin IRQ generates a pulse. This can be used to trigger the shutter to open, helping photographers to accurately capture the exciting moment of lightning.The maximum estimated distance of lightning strike is 40km. Limited by the inherent measurement method and algorithm, the distance estimation resolution is 1~4km, 40 km in 15 steps.Features Lightning detection within 40km in 15 steps Lighting intensity detection Used both indoors or outdoors Embedded man-made disturber rejection algorithm Applications Consumer Weather Station (thunderstorm measurement) Wearable Devices (outdoor thunderstorm early warning) Lightning Photography Specification Input Voltage : 3.3 V - 5.5 V Maximum Detection Range: 40 km Distance Detection Resolution: 1 km - 4 km Intensity Detection Resolution: 21 bits, i.e. 0 ~16777201 I2C Address: Three options 0x03, 0x02, 0x01 Interface: Gravity I2C (logic level: 0-VCC) Dimension: 30 mm x 22 mm For more information, check out the DFRobot Gravity – Lightning Distance Sensor wiki page here.

Elektor Digital Assembly Language Essentials (E-book)
A Guide to Powerful Programming for Embedded Systems You must be a well-rounded professional to excel in the ever-evolving, rapidly developing embedded design and programming industry. Simply put, when it comes to electronics design and programming, the more topics you can master, the more you’ll flourish at your workplace and at your personal workbench. This shouldn’t be a surprise, as the line between the skills of a hardware engineer and software engineer is blurring. The former should have a good grasp of programming in order to build efficient systems. The latter should understand the details of the design (whether it’s a physical or virtual application) for which he or she is writing code. Thus, to be successful, a modern professional electronics engineer must have a solid grasp of both hardware design and programming. Assembly Language Essentials is a matter-of-fact guide to Assembly that will introduce you to the most fundamental programming language of a processor. Unlike other resources about Assembly that focus exclusively on specific processors and platforms, this book uses the architecture of a fictional processor with its own hardware and instruction set. This enables you to consider the importance of Assembly language without having to deal with predetermined hardware or architectural restrictions. You’ll immediately find this thorough introduction to Assembly to be a valuable resource, whether you know nothing about the language or you have used it before. The only prerequisite is that you have a working knowledge of at least one higher-level programming language, such as C or Java. Assembly Language Essentials is an indispensible resource for electronics engineering professionals, academics, and advanced students looking to enhance their programming skills. The book provides the following, and more: An introduction to Assembly language and its functionality Significant definitions associated with Assembly language, as well as essential terminology pertaining to higher-level programming languages and computer architecture Important algorithms that may be built into high-level languages, but must be done the “hard way” in Assembly language — multiplication, division, and polynomial evaluation A presentation of Interrupt Service Routines with examples A free, downloadable Assembler program for experimenting with Assembly
