In the Electronic world, communication protocols are the backbone links for an embedded system, thus they are very important for us Seeekers to understand what they are, why they are used, and the difference between communication protocols. Also please leave us feedback. We at Seeed Studio are hoping to turn this series of blogs into wiki articles, and appreciate any feedback. First thing first, wired communication protocols are simply a set of rules that allow two or more entities of a communication system to transmit information via physical medium.

Protocols can be implemented by both hardware and software or a combination of both. Further, each protocol has its own application area. In this blog, I will walk you though some of the most common communication protocols used in embedded designs, and of course there are plenty more for you to explore!

Inter system protocols are communications between two communicating devices i. A PC is generally the master or host and each of the peripherals linked to it act as slaves or devices.

USB 1. X and 2. Data is transmitted in the form of packets, which is composed of 8 bits 1 byte with the LSB Least Significant Bit transmitted first. The transmitter UART converts data from a controlling device like a CPU into serial form, transits it in serial to the receiving UART, which then converts the serial data back into parallel data for the receiving device. UART transmits data asynchronously, which means that no clock signal is needed in transmitting and receiving data.

Thus, UART uses start and stop bits with actual data bits. When the receiving UART detects a start bit, it starts to read the incoming bits at a specific frequency known as the baud rate. Both UARTs must operate at about the same baud rate. The Intra system protocol establishes communication between components within the circuit board. In embedded systems, intra system protocol increases the number of components connected to the controllers.

On device communication protocols are known as intra system communication protocols. Most of our Grove Modules communicate via these protocols. The master is the controlling device usually a micro-controller while the slave usually a sensor, display, or memory chip takes instruction from the master. Further, the SS line is used to select the appropriate slave by pulling the SS low where it is normally held high. If the SS line is low the chip will begin to take instruction from the master.

However a master must have multiple GPIO pins available if it is to speak with multiple slaves. To get around this, some devices will use a multiplexor to select the slaves.

SPI is full-duplex, meaning it is able to send and receive data simultaneously. This allows for faster overall throughput. With I2C, you are able to connect multiple slaves to a single master just like SPI or having multiple masters controlling single or even multiple slaves.

This is extremely useful when you are logging data into a single LCD from more than one micro-controller. Like SPI, I2C is synchronous, so the output of the bits is synchronized to the sampling of bits by a clock signal shared between the master and the slave.

The clock signal is always controlled by the master. CAN protocol can be defined as the set of rules for transmitting and receiving messages in a network of electronic devices. It was designed for robust and flexible performance in harsh environments, and particularly for industrial and automotive application.

In particular, CAN was developed to reduce cable wiring, so the separate electronic control units ECUs inside a vehicle could communicate with only pair of wires, as stated below. This blog briefly explained some of the most commonly used communication protocols used in embedded design, of which are used in different applications.

I hope this provides you a little background knowledge of our products and excite you to explore more. For more, please feel free to leave us a comment for the communication protocols you would like to like! Your email address will not be published.

In the environment of the automation of industrial processes, the communication between the devices that intervene in the control of these systems, is a key issue to allow not only a correct operation, but also the supervision and control of these processes. The communications between devices are carried out through the use of different industrial communications protocols.

The history of the Internet has its origin in the efforts of wide area networking that originated in several computer science laboratories in the United States , United Kingdom , and France. In the early s the NSF funded the establishment for national supercomputing centers at several universities, and provided interconnectivity in with the NSFNET project, which also created network access to the supercomputer sites in the United States from research and education organizations. Commercial Internet service providers ISPs began to emerge in the very late s. Limited private connections to parts of the Internet by officially commercial entities emerged in several American cities by late and , [5] and the NSFNET was decommissioned in , removing the last restrictions on the use of the Internet to carry commercial traffic. In the s, research at CERN in Switzerland by British computer scientist Tim Berners-Lee resulted in the World Wide Web , linking hypertext documents into an information system, accessible from any node on the network.

How to design a scalable communications infrastructure for IIoT sensor networks

Catharines, Ontario, Canada E-mail: mpilkington brocku. The replacement of inorganic semiconductors with molecule-based compounds for applications in current-to-light conversion has led to a significant increase in interdisciplinary collaborations worldwide, affording new improved organic-light emitting diodes OLEDs ripe for commercial applications, as well as light-emitting electrochemical cells LECs that have recently started to head to the market. This review highlights the role that transition metal coordination complexes TMCs have played in advancing the field of molecular electronics, from early conception to the advanced development of several polypyridyl complexes currently pursued for both OLED and LEC concepts. We discuss how molecular design is pivotal for fine-tuning color and optimizing power efficiencies, highlighting the key roles of the metal, cyclometalate, and ancillary polypyridyl ligands.

Software is the key enabling technology KET as digitalization is cross-cutting future energy systems spanning the production sites, distribution networks, and consumers particularly in electricity smart grids. In this paper, we identify systematically what particular software competencies are required in the future energy systems focusing on electricity system smart grids. Our instrumental method is software competence development scenario path construction with environmental scanning of the related systems elements. The vision of future software-enabled smart energy systems with software houses is mapped with the already progressing scenarios of energy systems transitions on the one hand coupled with the technology foresight of software on the other hand.

Industrial Internet of Things IIoT applications, featured with data-centric innovations, are leveraging the observability, control, and analytics, as well as the safety of industrial operations. The wireless system design for IIoT applications is inherently a joint effort between operational technology OT engineers, information technology IT system architects, and wireless network planners. In this paper, we propose a new reference framework for the wireless system design in IIoT use cases.

IIoT applications like remote monitoring and predictive maintenance require massive sensor networks that can continously capture granular data from assets and their functioning environments. With the explosion of data acquisition points and traffic at the edge, industrial companies are in critical need of a scalable machine-to-machine M2M communications architecture. Engineering a scalable solution from the beginning minimizes the need for expensive modifications in the future, thereby securing long-term return-on-investment ROI. However, building such an architecture does not come without challenges. Network capacity Network capacity refers to the amount of traffic a network can handle at a given time. High network capacity allows for seamless and reliable system operations as the number of end nodes continuously grows. Self-interference caused by confined radio resources, is the number one issue that dampens network capacity in wireless IIoT networks. Devices deployed within the operating range of each other and sending data using the same frequency band vie for the use of that shared radio resource. The higher the device density and the more frequent the data transmission in a network, the more likely multiple messages are sent simultaneously. This leads to packet collisions and eventually, data loss. Often, self-interference is further complicated by a light-weight, asynchronous medium access control MAC protocol such as ALOHA, adopted by many low-power wireless technologies.

Future smart energy software houses

Embedded computer systems literally surround us: they're in our cell phones, PDAs, cars, TVs, refrigerators, heating systems, and more. In fact, embedded systems are one of the most rapidly growing segments of the computer industry today. Along with the growing list of devices for which embedded computer systems are appropriate, interest is growing among programmers, hobbyists, and engineers of all types in how to design and build devices of their own. Furthermore, the knowledge offered by this book into the fundamentals of these computer systems can benefit anyone who has to evaluate and apply the systems. The second edition of Designing Embedded Hardware has been updated to include information on the latest generation of processors and microcontrollers, including the new MAXQ processor. If you're new to this and don't know what a MAXQ is, don't worry--the book spells out the basics of embedded design for beginners while providing material useful for advanced systems designers. Designing Embedded Hardware steers a course between those books dedicated to writing code for particular microprocessors, and those that stress the philosophy of embedded system design without providing any practical information. Having designed 40 embedded computer systems of his own, author John Catsoulis brings a wealth of real-world experience to show readers how to design and create entirely new embedded devices and computerized gadgets, as well as how to customize and extend off-the-shelf systems. Loaded with real examples, this book also provides a roadmap to the pitfalls and traps to avoid.

CAN Bus: The Central Networking System of Vehicles

The IoT revolution, requiring a dramatic increase in strong, secure communication links, offers providers an opportunity to not only play a larger role but to create new value. The Internet of Things IoT has become increasingly visible thanks to the rise of intelligent thermostats, interactive fitness trackers, and the promise of autonomous vehicles. Such technologies are compelling because they make the things around us smarter and more interactive. Connecting all these devices is what turns isolated pockets of technology into a network that generates and pools data in ways that lead to valuable insights. Thanks to the central role of communications in many IoT deployments, how companies create value is often a function of the interaction between sensor technology and the network layer. Linking new and legacy sensors within an IoT ecosystem often means that companies seeking to realize value from the IoT need to work closely with their communication services providers CSPs. Such collaboration is unlikely to come easily to either party. Consumers of communications services can easily overlook the challenges associated with creating the sort of connectivity required to realize the full benefit of IoT technology.
