All About Embedded Systems


Embedded Systems are the crucial components of the modern compacted devices with multifunction capabilities. Embedded systems are specific computer programs that combine the functions of specially designed software and hardware and are completely encapsulated by the devices that they control. An embedded system has specific requirements and performs pre-defined tasks, unlike a general-purpose personal computer. An embedded system is a programmed hardware device. A programmable hardware chip is the platform and it is programmed with particular applications. Embedded systems are a combination of hardware and software which facilitates mass production and a host of applications.

Embedded systems constitute the widest possible use of computer systems.They include all computers specifically intended as special-purpose computers. Examples of embedded systems range from a portable music player, to real-time control of systems like the space shuttle. They are identified by their functions.The majority of commercial embedded software systems are designed to perform selected functions. These systems have to overcome resource constraints and system specifications. These systems meet their real-time constraints with a combination of special purpose hardware and software custom-developed to cope with the system requirements.

The embedded processor chip has the freedom to determine the data route , handle graphics and animation requirements and almost the entire functionalities of the device in which it is embedded. This allows the architecture of an embedded system to be simple and straight forward.For embedded systems, a real-time operating system is very essential to enable it to work efficiently within the resources parameters. The softwares specially developed for embedded hardware systems, especially those without a disk drive are named firmwares. Programs on an embedded system often run with real-time constraints with limited hardware resources. In many cases there are no disk drive, operating system, keyboard or screen. The software may not have anything remotely like a file system, or if one is present, a flash drive may replace rotating media. If a user interface is present, it may be a small keypad and liquid crystal display.

Embedded systems are normally resident in machines that are expected to run continuously for years without errors. Therefore the software and Firmware is usually developed and tested very rigorously and meticulously. Embedded systems generally avoid mechanical moving parts such as Disk drives, switches or buttons because these are unreliable compared to solid-state parts such as Flash memory. Solid State electronic components form the major part of a device with an embedded system.

The embedded system must have the unique quality and functionality of being able to restart itself even if catastrophic data corruption has taken place. This is usually accomplished with a standard electronic part called a watchdog timer that resets the computer unless the software periodically resets the timer. Embedded systems today rely on trusted Chip and processor makers like Intel, AMD and the like. Embedded softwares are being developed by developers who deploy time-tested methods like compilers,assemblers and debuggers to develop embedded system software.

A wide range of embedded systems exists on the market. Many products that feature embedded systems are small, relatively inexpensive and have a short lifetime of a few years before the next-generation product replaces them. Examples are mobile phones and other home electronics. In contrast, large, expensive and complex capital equipment, such as telephone switches, automobiles, airplanes, and industrial machines, are often safety-critical and in operation for several decades. All embedded systems, however, form part of a larger product. The buyer is primarily interested in the benefits the product brings and not in the embedded system. The emergence of embedded systems in devices has resulted in a dramatic increase in products incorporating Embedded Software. The most recent generation of embedded systems relies heavily on embedded software. As a matter of fact, many of their features, which used to be controlled by electronics or mechanical components until a few years ago, are now software controlled. Current trends reveal that functionality that traditionally was implemented in hardware is now implemented in software. The reliance of specially developed software for embedded systems has led to the mushrooming of companies specialising in embedded software development .

Embedded systems are going to be the focus of intensive and aggressive development in the years to come. With the world going in for devices that are compact and palm-sized, the need for advanced microporcessors and embedded softwares is huge. Embedded software developers and embedded hardware manufacturers are going to revel in the boom time that would witness a new peak in global demands for these specialized hardware-software combinations.

>>> Your Search for In-depth Embedded System Programming Course ends here!! <<<
If you want to know how to kick start embedded programming skill and level up your career, read on. Hello, my name is Arabinda Verma and I have spent more than 15 years in research & software development, trained hundreds of graduates in programming and software engineering. When I ask students to tell me what their biggest challenge while learning Embedded Programming is, they all say the same thing: “Fundamentals are not clear.” To really become comfortable with embedded systems, students need guidance, mentorship, and practice. This isn’t always the case in programming schools and universities despite the high investments in time and money that they require.
This made me design this course, which will take you from the basics of embedded training to the advanced microcontroller architectures.

Why this course?

Embedded systems might appear complex to newcomers or even experienced programmers. With a different pedagogic approach, this course will help you become familiar with different aspects of this area, which will prove particularly helpful regardless of your experience in programming.
The course helps you build a sound understanding of C & Assembly programming. It discusses the architecture of the ATMega328 microcontroller and how software and hardware interact. You will gain here foundational knowledge, applied skills, hands-on programming exercises, proper guidance and mentorship.

I strongly believe that even the most complex contexts can be broken down to be assimilated by all students, regardless of their level.

Plus a 30 DAY MONEY BACK GUARANTEE if you're not satisfied for any reason.


What you will gain from this course?

You will rig-up the development board using the basic electronic components like capacitors, resistors, LEDs, microcontroller etc. And interface the development board with PC through USB-serial adapter and in-circuit programming. You shall setup the development environment on PC, configure the microcontroller and flash the bootloader.

You will learn memory management through the C compiler, microcontroller architecture, instruction execution, interrupt handling and cross-language programming. You shall implement programs using the C and Assembly programming languages and implement pre-main functionalities to bring up the development board. These topics not only introduce you to the programming but also prepare you to deal with the ecosystem of programming an embedded system.


What other students are saying about this course?

Lots of students have already taken the right decision by enrolling in the course. Following is what they are saying.

"........ Arabinda Verma has done an excellent job of making the basic of microcontroller for anyone who is struggling in developing embedded concepts. Furthermore, after completing internal's and peripherals very clear through his tutorials. It serves as a good foundation course the course I am more confident in writing my own drivers for the microcontroller. For the best result, I would suggest to purchase any hardware board of AVR architecture and implement the code discussed in the tutorials. I am also looking forward to Arabinda's other tutorial. Happy Learning :)" -Yousuf
"Awesome course for beginners to build foundation of embedded system and C programming. The best part of the course is to build the development board on the breadboard and run/test programs........." - Akash

"Very useful course to learn and understand embedded systems." - Ajaganna
