To develop skills to write embedded C program for arithmetic operations.

Exp 05 Aim: To develop skills to write embedded C program for arithmetic operations.

For Addition

Algorithm: 

1. Declare 3 unsigned char variables and 1 unsigned int variable
2. Make P1 and P2 as Output
3. Assign data to two variables
4. Do the addition
5. Display the result on port 1
6. Multiply two numbers
7. Display result on port 2
8. Stop
   

Flow chart: 

Program:

#include<reg51.h>  void main (void) {       unsigned char p,q,r; unsigned int s;      P1=0x00;      P2=0x00;       p=0x04;       q=0x02;       r= p+q;       P1=r;      s=p*q;      P2=s;       while(1);   }

/* Special function register declarations */ /* for the intended 8051 derivative */   //Declare three 8 bit characters //Declare one 16 bit integer // P1 as outpour port // P2 as outpour port //Assign values to character   //Perform the addition //Display addition result on P1 //Perform the multiplication // Display multiplication result on P2

For Subtraction

Algorithm: 

1. Declare 3 unsigned char variables and 1 unsigned int variable
2. Make P1 and P2 as Output
3. Assign data to two variables
4. Do the subtraction
5. Display the result on port 1
6. division two numbers
7. Display result on port 2
8. Stop

Flow chart: 

Program:

#include<reg51.h>  void main (void) { unsigned char p,q,r; unsigned int s; P1=0x00; P2=0x00; p=0x04; q=0x02; r= p+q; P1=r; s=p/q; P2=s; while(1); }

/* Special function register declarations */ /* for the intended 8051 derivative */   //Declare three 8 bit characters //Declare one 16 bit integer // P1 as outpour port // P2 as outpour port //Assign values to character   //Perform the addition //Display subtraction result on P1 //Perform the division // Display division result on P2

Conclusion: In this experiment we performed different programs on Keil and observed the output.
