code problem – using 8051 microcontroller (AT89S52)

[Muhamad Reduan Bin Azlee Lee]

I have problem when compiler this code, can anyone help me?

I use keil software.. This is the problem that i got

 

Build target 'Target 1'

compiling My.c…

My.c(2): warning C318: can't open file 'lcddisplay.h'

My.c(16): warning C206: 'lcd_init': missing function-prototype

My.c(17): warning C206: 'lcdcmd': missing function-prototype

My.c(17): error C267: 'lcdcmd': requires ANSI-style prototype

Target not created.

This is my code..

 

#include<reg51.h>

#include"lcddisplay.h"

#include<intrins.h>

sbit rd = P2^0;

sbit wr = P2^1;

sbit intr = P2^2;

sbit finger = P2^5;

sbit buz = P2^3;

#define adcdata P3

void convert(unsigned char );

unsigned char a,pp=0,count=0,i;

void main()

{

buz=0;

finger=1;

lcd_init();

lcdcmd(0x85);

msgdisplay("WELCOME");

lcdcmd(0x01);

msgdisplay("temp hbeat");

rd=1;

intr=1;

adcdata=0xff;

while(1)

{

lcdcmd(0xc2);

//delay(500);

wr=0;

_nop_();

_nop_();

_nop_();

_nop_();

wr=1;

delay(50);

rd=0;

delay(10);

a=adcdata;

convert(a);

delay(500);

for(i=0;i<100;i++)

{

count+=1;

if(finger==0)

{

delay(1000);

if(!finger)

{

buz=1;

delay(500);

pp=1;

buz=0;

break;

}

else

pp=0;

}

}

delay(500);

lcdcmd(0xca);

if(pp)

{

convert(count);

}

else

convert(0);

pp=0;

}

}

void convert(unsigned char temp_value)

{

unsigned char value,d1,d2,d3;

temp_value = temp_value;

value=temp_value/10;

d3=temp_value%10;

d1=value/10;

d2=value%10;

d1=d1+0x30;

lcddata(d1);

delay(10);

d2=d2+0x30;

lcddata(d2);

delay(4);

// msgdisplay(".");

d3=d3+0x30;

lcddata(d3);

delay(10);

}
