STRUCTURES

An array is collection of the elements of same type , but many time we have to store the elements of the different data types. A structure is a user defined data type in C.  A structure creates a data type that can be used to group items of possibly different types into a single type.Each element of a structure is called a member.It is widely used to store student information, employee information, product information, book information etc.

Defining a structure

Structure is defined by using struct statement.
struct [structure tag] {

   member definition;
   member definition;
   ...
   member definition;
}
The structure tag is optional and each member definition is a normal variable definition, such as int i; or float f; or any other valid variable definition.

INTERFACING SEVEN SEGMENT DISPLAY WITH 89c51

Image
Seven segment displays are important display units in Electronics and widely used to display numbers from 0 to 9. It can also display some character alphabets like A,B,C,H,F,E etc. It just consists 8 LEDs, each LED used to illuminate one segment of unit and the 8 th  LED used to illuminate DOT in 7 segment display. There are two types of 7 segment displays: Common Anode and Common Cathode: Common Anode:  In this all the Negative terminals (cathode) of all the 8 LEDs are connected together (see diagram below), named as COM. And all the positive terminals are left alone. Common Cathode:  In this all the positive terminals (Anodes) of all the 8 LEDs are connected together, named as COM. And all the negative thermals are left alone. For constructing the truth table , listing the 7 display input signals, decimal number and corresponding 4 digit binary numbers. The truth table for the decoder design depends on the type of 7-segment display.  Her...

Liquid crystal display is very commonly used electronic display module and having a wide range of applications such as calculators, laptops, mobile phones etc. 16×2 character lcd display  is  very basic module which is commonly used in electronics devices and projects. It can display 2 li nes of 16 characters . Pinout and Pin Description of 16x2 LCD Module Pin No   Function   Name 1 Ground (0V) Ground 2 Supply voltage; 5V (4.7V – 5.3V)  Vcc 3 Contrast adjustment; through a variable resistor  V EE 4 Selects command register when low; and data register when high Register Select 5 Low to write to the register; High to read from the register Read/write 6 Sends data to data pins when a high to low pulse is given Enable 7 8-bit data pins DB0 8 DB1 9 DB2 10 DB3 11 DB4 12 DB5 13 DB6 14 DB7 15 Backlight V CC  (5V) Led+ 16 Backlight Ground (0V) Led-...

POINTERS

Image
A  pointer  is a variable whose value is the address of another variable, i.e., direct address of the memory location. Concept of pointer Consider the declaration, int i=3; This declaration tells the C compiler to: (a) Reserve space in memory to hold the integer value. (b) Associate the name i with this memory location. (c) Store the value 3 at this location . Here the memory mapping is depicted: We can access the value 3 by either using the variable name i or the address 65524. Since the memory addresses are simply numbers they can be assigned to some other variable. The variable that holds memory address are called pointer variables. A pointer variable is therefore nothing but a variable that contains an address, which is a location of another variable. Value of pointer variable   will be stored in another memory location. Here j is not an ordinary variable like any other integer variable....
