Embedded Systems Updates

Note: if GCC is not available in your Ubuntu Linux machine install by using below command

$sudo apt-get install gcc-4.9

Here 4.9 is GCC version

Similarly for installing vim

$ sudo apt-get install vim

Below are the steps we have to follow for compiling a c programming file on Linux(Ubuntu):

1) create a .c file using the below command

$vim demo_prog.c

2) write some logic based on your requirement and save using by pressing escape key and type " :wq "

3) compile the demo_prog.c using GCC

$gcc demo_prog.c

4) if no syntax errors in your demo_prog.c file then GCC compiler creates a.out file.

5) run a.out file

$./a.out

Embedded Software is a key element in every embedded project that is used to run the micro-controller to perform the desired operations. In our daily life, we frequently use many electronic devices such as washing machines, refrigerators, mobile phones, security system, digital camera so on which will be controlled using embedded C program. If you press a button to take a photo with your digital camera, then micro-controller will perform the functions essential to capture the image and store it. This article presents basics of embedded systemsmicro-controller consists of many ports to construct the embedded C programming tutorial An embedded systemis the one that has computer-hardware with software integrated in it as the most significant component. It is a dedicated computer-based system, may be independent or part of a large system with the following components:
1. Hardware: It includes processor, timers, I/O devices, ports, memories, ports, etc.
2. Application software: To perform multiple tasks at the same time.
3. Real Time Operating System (RTOS): It supervises the application software and provides a mechanism to let the processor run a process as per scheduling and perform the context-switch between different processes.

7-Steps to Building Embedded C

1. Comments
2. Preprocessor directives
3. Port configuration
4. Global variables
5. main() function or core function
6. Variable declaration
7. Program Logic

 You have to do at least six months course in Embedded System according to the demand.

You have many options like you can do training in following microcntroller of Embedded System .

1) 8051

2) ARM

3) PIC

4) AVR

5) Arduino

6) Raspberry Pi

Or you can also choose Embedded System with Robotics

Of course, the future of our technology is clearly moving towards embedded system only. To be clear, in real world application like automobile electronic systems, wireless Electronic door locks, automatic doors,.. etc are good examples of real time applications. Even in Industrial and Research also moving towards the same. We say Robotics but the basic of Robotic is nothing but the Embedded system. The definition of Embedded system " controlled by a real-time operating system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Wikipedia", to be short as per my definition, when you control any electrical equipment which do some physical work done by using a certain pre programmed codings and some logic with help of various Electronic components.

Now the answer to your question is, it is very good for an electrical engineer could study Embedded system will make his opportunity and scope very wide. And definitely will be a needed engineering in future.
