- An embedded system is an electronic system that has a software and is embedded(uploaded) in Embedded hardware.
- The first real time modern Operating system was Apollo Guidance Computer developed in 1960s, by Dr. Charles Stark Draper at the Massachusetts Institute of Technology for Apollo Program
- The first Embedded system for a vehicle was released in 1968, by VOLKSWAGEN. Its uses microprocessor to control its electronic fuel Injection system. And by early 1970s, the price of the Integrated Circuits dropped and the first Microcontroller was developed by Texas Instrument in 1971
- Furthermore, In the year 1971, Intel released the first commercially available microprocessor unit named as the Intel 4004 – an early microprocessor that is still required support chips and external memory
- And now, the micro-controller based embedded system would go on to be incorporated into every aspects of consumers daily lives, from credit card readers and cell phones, to traffic lights and thermostats.
Embedded System Definition:
Before coming to learn Embedded System, Let’s discuss about the word SYSTEM mean, A system is an arrangement where all of its component work according to the specific defined rules by the method of organizing, working, or performing one or more tasks according to the plan process.
Embedded System:
Embedded System is a dedicated system which is used to perform the specific task by the combination of computer hardware and software designed for a specific function. Embedded systems may also function within a larger system.
Industrial machines, consumer electronics, agricultural and processing industry devices, automobiles, medical equipment, cameras, digital watches, household appliances, airplanes, vending machines and toys, as well as mobile devices, are possible locations for an embedded system.
Examples of embedded systems
Embedded systems always function as part of a complete device — that’s what’s meant by the term embedded. They are low-cost, low-power-consuming, small computers that are embedded in other mechanical or electrical systems. Generally, they comprise a processor, power supply, and memory and communication ports. Embedded systems use the communication ports to transmit data between the processor and peripheral devices — often, other embedded systems — using a communication protocol. The processor interprets this data with the help of minimal software stored on the memory. The software is usually highly specific to the function that the embedded system serves
The processor may be a microprocessor or microcontroller. Microcontrollers are simply microprocessors with peripheral interfaces and integrated memory included. Microprocessors use separate integrated circuits for memory and peripherals instead of including them on the chip. Both can be used, but microprocessors typically require more support circuitry than microcontrollers because there is less integrated into the microprocessor. The term system on a chip (SoC) is often used. SoCs include multiple processors and interfaces on a single chip. They are often used for high-volume embedded systems. Some example SoC types are the application-specific integrated circuit (ASIC) and the field-programmable gate array (FPGA).
Often, embedded systems are used in real-time operating environments and use a real-time operating system (RTOS) to communicate with the hardware. Near-real-time approaches are suitable at higher levels of chip capability, defined by designers who have increasingly decided the systems are generally fast enough and the tasks tolerant of slight variations in reaction

- Placements: Ensure that they are providing with 100 % Placement service for each and every candidate after the completion of training. To make sure on that, they show the raise of counts for every month Placement with decent CTC package relevant to their experiences and type of an organization.
- Social Media links: Check whether the organization is active in all social media with their day-to-day updates on Facebook, Instagram, LinkedIn, etc.,
- Trainer Profile: Look at Trainer’s Background of that corresponding Institute and Experienced which they have. Also look for the company’s CEO profile and Background on LinkedIn, Facebook, Instagram, etc.,
- Course Details: Compare the course syllabus given in their schedule with the current Embedded Market Scenarios which helps you to develop the real time projects on your own. Make sure the syllabus covers all the topics which is in the current trends.
- Company Background: Ensure the company was registered legally with ISO standard certification. Also make sure that, they will provide the course completion certificate after training.
- Google Reviews: Check all the reviews given by the candidates from their website which is very genuine consist of candidate’s background history, their flexibility of learning and current employment status, not just like comments with best embedded training or good something like single words.
- Fee Structure: Before making a payment, check whether they provide a demo session or clear explanations of their syllabus taken forward to the training
Raspberry Pi
Raspberry Pi is normally called as small personal computer or mini-computer and this single board itself acts as a computer. USB Keyboard, USB Mouse and Monitor are connected as external devices to the Raspberry pi which will act as a Mini Pocket-sized personal computer. Below images shows Raspberry pi board.
Raspberry Pi has a lower config and specification than the Personal computer or Laptop but it is still a computer which can provide all the expected features or abilities at a low power consumption.
- Important point to note is that it needs to have an SD card (minimum 8 GB recommended) to store the OS (operating System). Raspberry Pi is more than a computer as it provides access to the on-chip hardware i.e., GPIOs for developing an application. By accessing GPIO, we can connect devices like LED, motors, sensors, etc and can control them too. It is also popularly known for building a Real Time Operating system(RTOS) from Linux Platform and it also can be used for real time Image/Video Processing, IoT based applications and Robotic Application.
- Raspbian OS is an official Operating System available for free to use. This OS is efficiently optimized to use with Raspberry Pi. Raspbian has a GUI which includes tools for Browsing, Python programming, office, games, etc. Raspberry Pi also provides on-chip SPI, I2C, I2S and UART modules. Raspberry Pi Foundation officially provides Debian based Raspbian OS. Also, they provide NOOBS OS for Raspberry Pi. We can also install several Third-Party versions of OS like Ubuntu, Arch Linux, RISC OS, Windows 10 IOT Core, etc.
- It has ARM based Broadcom Processor SoC along with on-chip GPU (Graphics Processing Unit)
- The CPU speed of Raspberry Pi varies from 700 MHz to 1.2 GHz. Also, it has on-board SDRAM that ranges from 256 MB to 1 GB.
Controller Area Network (CAN)
WHAT IS CAN?
- Controller Area Network (CAN) protocol was initially created by BOSCH in the mid-1980s for automotive applications as a method for enabling robust serial communication.
- CAN is an asynchronous Serial communication protocol.
- Controller Area Network (CAN) Bus was started in the year 1983 at Robert Bosch. In February 1986, Robert Bosch officially introduced the Controller Area Network (CAN) serial bus system at the Society of Automotive Engineers (SAE) congress. It was the turning point for one of the most successful network protocols ever.
- The first CAN Controller chips were introduced by Intel in the year 1987, and shortly after that Philips also introduced CAN Protocol
- The first production vehicle was released in the year 1991 by the Mercedes-Benz W140 to feature the CAN based multiplex wiring systems.
- Bosch published several versions of the CAN specification and the latest is CAN 2.0 published in 1991. This specification has two parts; part A is for the standard format with an 11-bit identifier, and part B is for the extended format with a 29-bit identifier. A CAN device that uses 11-bit identifiers is commonly called CAN 2.0A and a CAN device that uses 29-bit identifiers is commonly called CAN 2.0B. These standards are freely available from Bosch along with other specifications.
- CAN bus is one of five protocols used in the on-board diagnostics (OBD)-II vehicle diagnostics standard. The OBD-II standard has been mandatory for all cars and light trucks
CAN BENEFITS:
There are many reliable and obvious reasons why a CAN bus network is popular with Automotive Industries and IoT Solution Providers.
- Low cost:ECUs communicate via a single CAN interface – there are no analog signal lines, and this reduces errors during communication and weight of vehicle units thus making the cost lower.
- Centralized communication: CAN communication protocol allows for central error diagnostics and configuration of all vehicle ECUs.
- Robust communication: CAN bus communications are electromagnetic interference proof and are not sensitive to subsystem failures, which is very important for vehicles used in harsh conditions, for example, harvesting in very hot weather.
- Efficient code management: CAN messages are prioritized based on IDs – the highest priority IDs are non-interrupted. This is extremely important for timely vehicle maintenance or repair.
- Flexibility: In every ECU there is a chip that enables the unit to receive transmitted messages, decide its relevance, and act in accordance with the message. This makes the system customizable and allows adding extra nodes, such as CAN bus data logge
CAN APPLICATIONS:
Initially CAN was created for only Automotive Purpose, the most common part of application in CAN was In-Vehicle Electronic Networking. Moreover, many other industries came to realized such benefits and advantages of CAN Protocols over the past 20 years, they have come with the idea of using this bus for the wide variety of applications. Mostly used applications was listed below;
- Passenger vehicles, trucks, buses (combustion vehicles and electric vehicles)
- Agricultural equipment
- Electronic equipment for aviation and navigation
- Industrial automation and mechanical control
- Elevators, escalators
