HI ,

THIS IS THE CODE FOR MY pic16F877A .I want it to display HELLO WORLD on my LCD ,

But getting no output , Absolutely

 

 

 

 

#include<htc.h>

 

#define LCD_PORT PORTD

#define LCD_PORT_DIRECTION TRISD

#define LCD_CON_DIRECTION TRISB

#define RS RB1

#define RW RB2

#define E  RB4

 

 

 

 

char hello[11]=”HELLO WORLD”;

 

 

 

 

void delay(int itime)

{

int i,j;

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

for(j=0;j<135;j++);

}

 

void IO_inti()

{

LCD_PORT_DIRECTION=0;

LCD_CON_DIRECTION =0;

 

}

 

 

/************** LCD COMMAND SEND *****************/

void lcd_cmd(char cmd1)

{

LCD_PORT=cmd1;

RS=0;

RW=0;

E=1;

delay(2);

E=0;

 

}

/*************************************************/

 

 

/************** LCD DATA SEND ********************/

void lcd_data(char data1)

{

LCD_PORT=data1;

RS=1;

RW=0;

E=1;

delay(2);

E=0;

}  

/*************************************************/

 

 

/************** LCD INITIALIZATION ***************/

void lcd_inti()

{

lcd_cmd(0x01); // clear screen

delay(10);

 

lcd_cmd(0x06); // 

delay(10);

lcd_cmd(0x80); // force cursor to 1st line

    delay(10);

 

}

/************************************************/

 

 

 

/**************** MAIN ROUTIINE ****************/

void main()

{

 

int i,j,k;

IO_inti();

lcd_inti();

 

while(1)

{

for(i=0;i<11;i++)

{

lcd_data(hello);

delay(1000);

}

 

 

 

}

 

}
