For the longest time the major misconception about Controller Area Network CAN was that it is merely used in automobiles. The truth is, CAN, since its introduction in , proved to be a robust, simple and versatile technology and, consequently, CAN found its way into all areas of applications where microprocessors need to communicate among each other.

The troops had come under heavy enemy fire just before dawn and the garrison was caught totally by surprise. The fort commander had been awakened by the gunfire and issued a message to be dispatched immediately. The message was taken to the telegraph office where an elderly telegraph operator furiously typed out the message in the format of on-and-off electrical pulses called Morse code. This coded message went out on the telegraph wire where other telegraph operators listened and then went to work decoding the pulses. As outdated as this example is, the truth is that something very close to this scenario occurs in the modern automobile.
Introduction to CAN (Controller Area Network)
While the Arduino is not widely considered an industrial-strength solution, it provides, due to its low price and ease of programming, the perfect prototyping platform for all kinds of Controller Area Network CAN Bus applications. This online book guides the reader through the process of acquiring all necessary hardware and software components, the implementation of the CAN Bus driver, and the implementation of programs Arduino Sketches to read, send, process, and display data from and to a CAN network. However, references to Arduino basics may appear but only in passing. I will refer briefly to some aspects of the CAN Bus, but these are the mere basics of the actual protocol, just enough to understand the concept. All we need to do in this book is to receive, transmit, and process data. The rest is up to your fantasy. I have chosen to give this book away as a free download and to post it on this website in its entirety.
This article introduces the Controller Area Network CAN serial communication bus, detailing message frames, bus arbitration, and signaling. The Controller Area Network CAN is a serial communication bus designed for robust and flexible performance in harsh environments, and particularly for industrial and automotive applications. Originally invented by Bosch and later codified into the ISO standard, CAN defines the data link and physical layer of the Open Systems Interconnection OSI model, providing a low-level networking solution for high-speed in-vehicle communications. In particular, CAN was developed to reduce cable wiring, so the separate electronic control units ECUs inside a vehicle could communicate with only a single pair of wires. Onboard diagnostics OBD is your vehicle's diagnostic and reporting system that allows you or a technician to troubleshoot problems via diagnostic trouble codes DTCs.
A Comprehensible Guide To Controller Area Network
It seems that you're in Germany. We have a dedicated site for Germany. Authors: Di Natale , M. This book to offers a hands-on guide to designing, analyzing and debugging a communication infrastructure based on the Controller Area Network CAN bus. Although the CAN bus standard is well established and currently used in most automotive systems, as well as avionics, medical systems and other devices, its features are not fully understood by most developers, who tend to misuse the network. This results in lost opportunities for better efficiency and performance.
Information sensed by one part can be shared with another. A modern car may have up to 70 ECUs - and each of them may have information that needs to be shared with other parts of the network. Specifically, an ECU can prepare and broadcast information e. In more technical terms, the controller area network is described by a data link layer and physical layer. The CAN bus physical layer defines things like cable types, electrical signal levels, node requirements, cable impedance etc. For example, ISO dictates a number of things, including below:. In the context of automotive vehicle networks, you'll often encounter a number of different types of network types.
This is the first book to offer a hands-on guide to designing, analyzing and debugging a communication infrastructure based on the Controller Area Network CAN bus. Although the CAN bus standard is well established and currently used in most automotive systems, as well as avionics, medical systems and other devices, its features are not fully understood by most developers, who tend to misuse the network. This results in lost opportunities for better efficiency and performance. This book offers a comprehensive range of architectural solutions and domains of analysis. It also provides formal models and analytical results, with thorough discussion of their applicability, so that it serves as an invaluable reference for researchers and students, as well as practicing engineers.

- Она бросила пачку компьютерных распечаток ему на стол. - Я что, бухгалтер. - Нет, милый, ты директорский автопилот. Надеюсь, не забыл. - Ну и что мне, прожевать все эти цифры.
Успокойся, Дэвид. Спокойно. Он оглядел пустой зал.
Под густым слоем краски он увидел не гладкие девичьи щеки, а густую щетину. Это был молодой человек. В верхней губе у него торчала серебряная запонка, на нем была черная кожаная куртка, надетая на голое тело. - Какого черта тебе надо? - прорычал он хриплым голосом - с явным нью-йоркским акцентом.
Ну что еще? - застонал. - Хочет предъявить мне обвинение во вторжении в личную жизнь. Девушка волокла за собой туристскую сумку.

Хорошо, - сказала. - Я немного погорячилась. - Немного? - Глаза Бринкерхоффа сузились. - У Стратмора стол ломится от заказов. Вряд ли он позволил бы ТРАНСТЕКСТУ простаивать целый уик-энд. - Хорошо, хорошо.
Беккер вежливо улыбнулся и вышел на улицу - в душную севильскую ночь. ГЛАВА 42 Вернувшись в комнату, Сьюзан, не находя себе места, нервно ходила из угла в угол, терзаясь мыслью о том, что так и не выбрала момент, чтобы разоблачить Хейла. А тот спокойно сидел за своим терминалом. - Стресс - это убийца, Сью. Что тебя тревожит.
Он подбежал к кассе. - El vuelo a los Estados Unidos. Стоявшая за стойкой симпатичная андалузка посмотрела на него и ответила с извиняющейся улыбкой: - Acaba de salir.
