C PROGRAMMING TUTORIAL

Software or Program

There are two components in computer system. First is Hardware and Another is software. Hardware is the parts of computer that can be touched and software is the part of computer system that can not be touched. The program that is contained in the computer memory is called software. In simple Software is the knowledge of computer system. Software is also called program. Creating or writing a program or software is called programming and the language in which we write a program is called programming language. There are many types of programming language but all of them are categorized under there groups. 

1. machine level language

2. assembly level language

3. high level language

machine level language is the code in binary number system and also arranged as hexadecimal code. They are very hard to write and understand since one character or alphabet contains long binary code.

Assembly level language is little bit easy than machine level language. It is used to achieve pin and port of hardware like processor and micro-controller .

ADDING FACEBOOK LIKE BOX ON BLOG

Hi guys . I am giving this technique to you to promote your facebook page and blog. Since i am also a blogger and I love blogging and sharing what I knows so I want you to do so.. So I am here presenting a technique to add facebook like box on your blog.. Please follow the steps..

=> go to the design of your blog as shown in figure below  .

SUBSTRACTION OF TWO 8 BIT NUMBERS USING 8085

AIM 

TO PERFORM THE SUBSTRACTION OF TWO 8 BIT NUMBERS USING 8085

ALGORITHM 

1. START THE PROGRAM BY LOADING THE FIRST DATA INTO ACCUMULATOR
2. MOVE THE DATA TO A REGISTER (B REGISTER)
3. GET THE SECOND DATA AND LOAD INTO ACCUMULATOR
4. SUBTRACT THE TWO REGISTER CONTENTS
5. CHECK FOR CARRY
6. IF CARRY IS PRESENT TAKE 2'S COMPLEMENT OF ACCUMULATOR
7. STORE THE VALUE OF BORROW IN MEMORY LOCATION

ADDITION OF TWO 8 BIT NUMBERS USING 8085 MICROPROCESSOR

AIM

TO PERFORM ADDITION OF TWO 8 BIT NUMBERS USING 8085

ALGORITHM

1. START THE PROGRAM BY LOADING THE FIRST DATA INTO THE ACCUMULATOR
2. MOVE THE DATA TO A  A REGISTER( B REGISTER)
3. GET THE SECOND DATA THE LOAD INTO ACCUMULATOR
4. ADD THE TWO REGISTER CONTENTS
5. CHECK FOR CARRY
6. STORE THE VALUE OF SUM AND CARRY IN MEMORY LOCATION

Harvard and Von-neumann Architecture of computer architecture and difference between them

Computer architecture is the internal structure system and system of functioning of of computer system. There are mainly two architecture of computer system.

1. VON NEUMANN COMPUTER ARCHITECTURE 

2. HARVARD ARCHITECTURE

In these days, digital system is used everywhere. Audio and video all are digitized to their digital signal by digital signal processor. So harvard architecture gives the use of such digital signal processing system.

1. von neumann architecture 

=> It is named after the mathematician and early computer scientist John Von Neumann.

=> It is used in conventional processors found in PCs and Servers, and embedded systems with only control functions.

=> The data and program are stored in the same memory

=> The code is executed serially and takes more clock cycles

=> There is no exclusive Multiplier

=> There is an Absence of Barrel Shifter

=> The programs can be optimized in lesser size

INTERFACING LCD WITH ARDUINO, ARDUINO BASIC

This is the basic idea of interfacing lcd with arduino. Idea is taken from the arduino official site.

Introduction 

The LiquidCrystal library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface.

This example sketch prints "Hello World!" to the LCD and shows the time in seconds since the Arduino was reset.

Arduino Based Voting System

Normal type of voting system is ancient and time consuming. The probability of getting error is also greater in that system. So use of embedded system makes the work technical, easy and yet reliable.  The complexity and robustness of a voting system depends on the number of voters involved. Here you could see a simple Arduino based voting system that would be a great fit for small-scale elections such as in schools or colleges. This system was designed to ensure security and the coolest thing is the whole voting process can be done with assembled hardware and Arduino IDE.

This voting system takes vote inputs from pins A2 to A5 of Arduino. A LCD used to show candidates name which was connected in 4 bit mode to the Arduino.
