Displaying a Word or String in an 16x2 LCD with PIC16F877A and MPLAB X

We have seen how to interface an LCD with PIC16F877A  . In this we are printing only a letter in the  LCD , now we are going to Display a string on the LCD  for this following steps are followed

First Create a MPLAB X project as in the steps for  Blinking a LED using MPLAB X , PIC16F877A

And check the  Interfacing LCD with PIC16F877A in MPLAB X  to know how to interface a LCD

Components
1.PIC16F877A micro controller
2. 2x16 LCD Display


we are using the following functions 

void delay(unsigned int msec) // Time delay function
void lcd_cmd(unsigned char item) // Function to send command to LCD
void lcd_data(unsigned char item) // Function to send data to LCD
void lcd_data_string(unsigned char *str) // Function to send data to string
void lcd(unsigned char str[10])

To display the string in  LCD , just call the below lines in main function

 lcd_cmd(0x01);
  lcd_cmd(0x86);
  lcd("STRING TO DISPLAY");

The functions are defined below 

void delay(unsigned int msec) // Time delay function
{
int i,j ;
for(i=0;i<msec;i++)
  for(j=0;j<1275;j++);
}

void lcd_cmd(unsigned char item) // Function to send command to LCD
{
dataport = item;
rs= 0;
rw=0;
en=1;
delay(1);
en=0;
return;
}

void lcd_data(unsigned char item) // Function to send data to LCD
{
dataport = item;
rs= 1;
rw=0;
en=1;
delay(1);
en=0;
return;
}

void lcd_data_string(unsigned char *str) // Function to send data to string
{
int i=0;
while(str[i]!='\0')
{
  lcd_data(str[i]);
  i++;
  //delay(10);
}
return;
}

void lcd(unsigned char str[10])
{
lcd_cmd(0x38);
lcd_cmd(0x0e);
lcd_data_string(str);
}
