LM35 temperature sensor interfacing with 80S52

[prajwal]

hi friends,

 

I am interfacing LM35 sensor with 8052. the code goes like this,

 

 

#include<reg52.h>

sbit ale = P2^4;

sbit oe = P2^5;

sbit sc = P2^6;

sbit eoc = P2^7;

sbit add_a = P2^0;

sbit add_b = P2^1;

sbit add_c = P2^2;

sfr result = P1;

void DelayMs(unsigned int count);

void main()

{

unsigned char value;

result=0xff;

eoc=1;

ale=0;

oe=0;

sc=0;

while(1)

{

add_c=0;

add_b=0;

add_a=1;

  DelayMs(1);

ale=1;

DelayMs(1);

sc=1;

DelayMs(1);

ale=0;

sc=0;

while(eoc==1);

while(eoc==0);

oe=1;

DelayMs(1);

value=result;

oe=0;

}

}

 

void DelayMs(unsigned int count)

{  // mSec Delay @ 11.0592 Mhz

    unsigned int i;                            

    while(count) {

        i = 115;

                while(i>0) i–;

        count–;

    }

}

 

 

At the end of the code i need to convert the adc output to temperature. pls help i have no idea of how to convert

Hi,

The best method is touse the printf function where you can make use of the %d option to convert the integer to string.
