Basics
In this tutorial we will interface LCD to LPC1768.
Here we will not go in details of LCD.
Still if you want to know it, click here.

Code
There is lot of stuff that can be done with the LCDs, to start with we will simple display a couple of strings on the 2 lines of the LCD.
For that initialize the LCD with LCD_Init(), here 8 bit mode, 2 lines and 16 characters per line.
The LCD_DisplayString() will disply the specified string.
If you want to explore more go through LCD API Reference.
/* note: Refer lcd.h file for Pin connections */ #include "lpc17xx.h" //Device Specific header file #include "lcd.h" //Explore Embedded LCD library /* start the main program */ int main() { /* Setup and initialize the microcontroller system */ SystemInit(); /* Initialize the lcd before displaying any thing on the lcd */ LCD_Init(8,2,16); /* Display "hello, world" on first line*/ LCD_DisplayString("Hello World"); /*Go to second line and display "good morning" */ LCD_GoToLine(2); LCD_DisplayString("Good Morning"); while(1); }
