PIC16F877A LCD Example

This is just an example to show how to interface 16x2 lcd with pic16f877a. The lcd is going to display "PIC16F877A" in the the first line and "LCD Example" in the second line. The code is written using MikroC compiler.
The  circuit diagram and MikroC code are below:





// LCD module connections
sbit LCD_RS at RB5_bit;
sbit LCD_EN at RB4_bit;
sbit LCD_D4 at RB3_bit;
sbit LCD_D5 at RB2_bit;
sbit LCD_D6 at RB1_bit;
sbit LCD_D7 at RB0_bit;
sbit LCD_RS_Direction at TRISB5_bit;
sbit LCD_EN_Direction at TRISB4_bit;
sbit LCD_D4_Direction at TRISB3_bit;
sbit LCD_D5_Direction at TRISB2_bit;
sbit LCD_D6_Direction at TRISB1_bit;
sbit LCD_D7_Direction at TRISB0_bit;
// End LCD module connections
char *text;
void main() {
TRISB = 0;
PORTB = 0;
Lcd_Init();
Lcd_Cmd(_LCD_CURSOR_OFF);        // cursor off
Lcd_Cmd(_LCD_CLEAR);             // clear LCD
text = "PIC16F877A" ;
Lcd_Out(1,4,text);
text = "LCD Example";
Lcd_Out(2,4,text);
while(1);                     //infinite loop
}
