## RTOS Task switching based on priority using LCD – CodesExplorer

Prerequisites:- The prerequisite for this program you should have knowledge of Simple LCD interfacing on ARM LPC2148. You can visit this post to get the program, algorithm about LCD interfacing.   Introduction:- In this post, We will be dealing with RTOS(Real-time Operating System) Program to switch the tasks based on the priorities.At first the OS is initialised […]

## RTOS program to generate Round Bin Multitasking algorithm

In this article let’s learn to assign tasks in round robin fashion. In the following program first, it assigns the highest priority to task1 and then it creates task2,task3. It continued the execution and waits for an event in task1, then suspends task1 and then enters into task2. Next, it waits for an event in […]

## ARM thumb program to find first 10 fibonacci numbers

In this article let’s learn how to find the first 10 Fibonacci numbers.Usually Fibonacci numbers start from 0,1,1,2……In this, we can observe that the present number in Fibonacci is the summation of the previous two numbers. So in this, we should initialize the first two numbers as -1 and +1 so that our algorithm works […]

## ARM assembly code to find number of ones and zeros in a 32 bit number

Hello guys! Today we will see how to find number of ones and zeros in a 32 bit number. Let’s first understand the algorithm later we see a example code. Algorithm: Start Store a 32 bit number in register(Rd). Initialize a counter register to 1Fh(32) Initialize one regiter(Ra) to zero to store number of ones, […]

## Embedded C to find the number of one's in a given 32bit number and optimize the code

Embedded C to find the number of one’s in a given 32bit number and optimize the code In this article let’s learn how to optimize a program.The program which is used for optimization is to find number of ones in a given 32bit number. First let’s write a simple code and then let’s see how […]

## ARM Assembly code to find number of positive numbers in an array

Let’s see how to write a ARM assembly code to find number of positive numbers in an array. ALGORITHM Start Load the base address of array. Initialize a counter register to number of elements in array. Initialize a register(Rd) to zero to store number of positive numbers. Load the value from array to a temporary […]

## ARM code: Assembly code to add numbers from array

ARM processor is used in all the Embedded systems that are being built now. Here I explain ARM assembly program to add numbers declared in an array. ALGORITHM: Start Create an array of numbers Initialize a counter register to the number of elements in an array Load base address of an array to a register. […]
