8051 Microcontroller interfacing with seven segment using Embedded C and simulation over proteous.

   

//this program run and compile with kiel uvision 3

// Here is your program :-

#include<reg51.h>

#define SegmentPort P1   //this line assigne variable segmentport to port P1

void MsDelay(int x) ;   //delay function prototype

void main()

{     

    unsigned char z,x ;

  char MyArray[]={0xc0,0xf9,0xA4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0xff} ;

    //this array content hex value equal to 0 to 9 decimal values this value can be change according to seven segment.

  SegmentPort = 0x00 ;  //here P1 define as a output port

   while(1)

    {

          for(z=0;z<=11;z++)

           {

                   P2 = MyArray[z] ;

                   MsDelay(4000); //this will generate 4 second delay

                   }

void MsDelay(int x) //this function takes value to generate dealy

{

        int i;

        for(i=0;i<x;i++)

        {

           TH0=0xFC;  //this values generate 1 ms delay but we write this code

           TL0=0x18; //in for loop this mean if we entere 4000 it will gives 4 sec   

            TR0=1;  // of delay

                while(TF0==0);

                TR0=0;

                TF0=0;

        }
