Hi guys in this article let’s learn about class.You might be thinking that you use class in every single program but don’t know what is class so let’s start.Hope you’ll enjoy it 🙂 Class is the core of Java.Each every single thing in java is referred as object and class. To understand the concept of […]
8051 itimer interrupt program to display value of 'Y' at P0 and 'n' at P2. Also generate square wave of 10 KHz at P2^0 with timer0 in interrupt mode.Using XTAL@22MHz
I have explained the calculations for the timer in my previous post.please have a look . CODE:

#include<REGx51.h> sbit sqwave=P2^0; void timer0() interrupt 1 {   sqwave=~sqwave;  //generating sq wave } void main() {  TMOD=0x02;  //Timer0 in 8 bit autoreload mode IE=0x82; //enabling intrupt TH0=0x47; //loading the calculated value    TR0=1;   //starting timer while(1) {  P0='y';  P2='n'; } } |
8051 timer Interrupt program to copy data from P0 to P1 ,while simultaneously generating square wave of time period 200 uS at P2^0 .
When it comes to interrupt programming , we have to consider some important registers. For this program the registers used are IE(interrupt enable),TCON(timer control),TMOD(timer mode). Â Â In timer interrupt programming calculating the value to be loaded to the timer is very important. Here XTAL frequency i have considered is 11.0592 MHz.If you are using […]
Difference between static and non-static methods in java
In this article let’s learn how static and non-static methods are used in a program.Usually when we want to access class members we create the object of the class and then access through the object as reference.There is another way to do this without creating the object(accessing directly by class name) i.e by using the […]

8051 Interrupts An Interrupt is an external or internal event that halts or interrupts Microcontroller to inform it that a device needs its service. Contents: 1. Basics.2. Steps taken when interrupt occurs. 1. Basics : A microcontroller is able to give service to many Input and Output devices connected to it. […]
Java program to find the sum of principal and secondary diagonal elements.
In this article let’s learn how to find the sum of principle diagonal elements and secondary diagonal elements. Principal diagonal elements are those which start at the top leftmost element of matrix and end at the bottom rightmost element of a matrix. Secondary diagonal elements are vice-versa. Eg: If A is the matrix of order […]
8051 Program to Rotate DPTR value
Output 8051 Program to Rotate DPTR Value. ALGORITHM: Start. Load the value to be rotated in DPTR. Move the Lower nibble of DPTR in Accumulator. Rotate Left 8 bits along with carry. Move the Upper nibble of DPTR in Accumulator. Rotate Left 8 bits along with carry. Now we got the Upper nibble of DPTR […]
8051 16 bit multiplication Program- Codes Explorer
8051 16 Bit Multiplication ALPÂ ALGORITHM: Start. Load the MSB’s of Data in two different registers. Load the LSB’s of Data in other two different registers. Successive multiplication is carried out. The product obtained in the registers. The output is stored in the registers. End. For example if we are trying to multiply two 16 […]
C++ : Read array of 10 Integers and Display
Read array of 10 integers and displaying them. “Array is the limited storage(as size mentioned) with ordered series or arrangement of same kind of data(int or float or char)” Example :Input is asked as : Enter the Array elements, Enter Values like 00,10,20,30,40,50,60,70,80,90 are stored in particular space of array. Example: – This represents that […]
C++ Program to Swap two numbers.
 “Swapping of integers is defined as the variables that are interchanged after swapping the variables,called as Swapping of integers” Example: If the input is given as a=5 and b=4 (before Swapping) The output will be as a=4 and b=5 (after Swapping).                Input: a=20 and b=40, before swapping. Output: a=40 and b=20, after swapping. […]
