A microcontroller is a computer-on-a-chip or a single-chip computer. Micro suggests that the device is small and controller tells you that the device might be used to control objects, processes or events. Another term to describe a microcontroller is embedded controller because the microcontroller and its support circuits are often built into or embedded in the devices they control. You can find microcontrollers in all kinds of things these days. Any device that measures, stores, controls, calculates, or displays information is a candidate for putting a microcontroller inside. The largest single use for microcontrollers is in automobiles. Every car manufactured today includes at least one microcontroller for controlling the engine and additional systems in the car. In desktop computers, you can find microcontrollers inside keyboards, modems, printers and other peripherals. In test equipment, microcontrollers make it easy to add features such as the ability to store measurements, to create and store user routines and to display messages. Consumer products that use microcontrollers include cameras, video recorders, compact-disk players and ovens.
The Intel 8051 microcontroller is one of the most popular general purpose microcontrollers in use today. It is about 30 years old and still very popular. One of the reasons for popularity of 8051-based microcontrollers is the availability of many excellent compilers, from freeware applications to high-priced professional development tools. The memory structure of the 8051 microcontroller is a complicated and you will definitely need an 8051 microcontroller tutorial to go deep into the concept.
The main reason for their great success and popularity is a skilfully chosen configuration which satisfies different needs of a large number of users allowing at the same time constant expansions. Besides, the software has been developed in great extend in the meantime, and it simply was not profitable to change anything in the microcontroller’s basic core. This is the reason for having a great number of various microcontrollers which basically are solely upgraded versions of the 8051 family.
A very popular programming language is C. It is widely used in development of operating systems, desktop applications and embedded systems. Beside assembly language, C is the most popular programming language used for embedded programming. C for 8051 microcontrollers has been the number one choice among programmers. 8051 microcontrollers are no exception. SDCC is the most popular open-source C compiler for 8051 microcontrollers. The importance of such microcontrollers is attracting many a professionals to take up 8051 microcontroller tutorials. These tutorials demonstrate how to code simple input & output. The tutorials assume basic knowledge of programming and electronics. Massive use of embedded microcontrollers encourages engineers and students to join microcontrollers’ tutorial and training for c programming for embedded microcontrollers so that they can grab new opportunities in the process of development.
