What is Embedded System ?

An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.[1][2] It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today

 An embedded system is a system that has software embedded into hardware, which makes a system dedicated for an application (s) or specific part of an application or product or part of a larger system. It processes a fixed set of pre-programmed instructions to control electromechanical equipment which may be part of an even larger system (not a computer with keyboard, display, etc.).

What is Embedded Systems Used For?

Embedded systems are considered when the cost of implementing a product designed in software on a microprocessor and some small amount of hardware, is cheaper, more reliable, or better for some other reason than a discrete hardware design. It is possible for one small and relatively cheap microprocessor to replace dozens or even hundreds of hardware logic gates, timing circuits, input buffers, output drivers, etc. It also happens that one generic embedded system with a standard input and output configuration can be made to perform in a completely different manner simply by changing the software.

The uses of embedded systems are virtually limitless, because every day new products are introduced to the markets that utilize embedded computers in novel ways. In recent years, hardware such as microprocessors, microcontrollers, and FPGA chips have become much cheaper. So when implementing a new form of control, it's wiser to just buy the generic chip and write your own custom software for it. Producing a custom-made chip to handle a particular task or set of tasks costs far more time and money. Many embedded computers even come with extensive libraries, so that "writing your own software" becomes a very trivial task indeed.

How to program for embedded system?

Get to know the features and operational characteristics of the microcontroller. The manufacturer's datasheet for each microcontroller contains details about the features and operations
