Time Narration
00:01 Welcome to the Spoken Tutorial on Interfacing LCD through AVR-GCC programming.
00:09 In this tutorial, we will learn to:

interface a LCD to Arduino board,

write an AVR-GCC program to display a digit on LCD.

00:22 To follow this tutorial, you should have basic knowledge of :

electronics,

C Programming and

AVR-GCC.

00:34 To record this tutorial, I am using:

Arduino UNO Board,

Ubuntu Linux operating system version 14.04.

00:47 We also require some external devices such as:

Breadboard,

LCD 16 by 2,

Arduino UNO Board,

01:00 Potentiometer,

Jumper Wires and

Pin headers.

01:07 In this experiment, we will be using a 16 by 2 LCD.

Please refer to the basic level tutorials of this series to know more about LCD.

01:20 Make use of the given table to connect the Arduino pins to the LCD.
01:26 This table is available in the Additional reading material link of this tutorial.
01:32 This is the circuit connection.
01:35 Connect one extreme lead of the potentiometer to pin 1 of the LCD.
01:42 The other extreme end is connected to pin 2 of the LCD.

The middle pin is connected to pin 3 of the LCD.

01:53 This is the live setup of the connection.
01:58 Now, we will write an AVR-GCC program to display the digit 5 on the LCD.
02:05 Open any text editor and type the following.
02:09 avr/io.h contains all the basic libraries required to perform the input and output operations.
02:19 Util slash delay.h contains the libraries for the delay function.
02:26 stdlib.h contains the libraries for defining variable types and other commonly used functions.
02:36 ClearBit(x comma y) is equivalent to cbi(x comma y). This is used to clear the yth bit of PORTx.
02:47 SetBit(x comma y) is equivalent to sbi(x comma y). This is used to set the yth bit of PORTx.
02:58 All the numerical pins of the LCD are replaced with the names using hash define.
03:05 This is done to make the program easier to understand.
03:10 The PulseEnableLine function is used to toggle the enable pin of the LCD.
03:17 SetBit will set to high and Clearbit will set to low, with a delay in between.
03:25 The SendNibble function is used to send data of one nibble to the PORTB.
03:33 The SendByte function is used to send data of one byte to the PORTB.
03:40 The LCD underscore Cmd function is used to send a command to the LCD.
03:47 The LCD underscore Char function is used to send a character data to the LCD.
03:55 The LCD underscore Init function is used to initialize the LCD.
04:02 The LCD underscore Clear function is used to clear the display.
04:09 The LCD underscore Message function is used to send a string of data to be displayed on the LCD.
04:18 The LCD underscore Integer function is used to send an integer data to the LCD.
04:27 This is the main function where we pass the value 5 to the display.
04:33 This code is available in the Code files link of this tutorial. You can download and use it.
04:41 I’ll save the code as lcd.c file in the Downloads folder.

Ensure that the Makefile is also present in the same folder.

04:53 Switch to the terminal.
04:56 Go to the folder where lcd.c file is saved.

Type: make space FNAME in capital = lcd and press Enter.

05:12 This command creates a .hex file and uploads it to Arduino.
05:18 Now, you can see that the digit 5 is displayed on the LCD.
05:25 This brings us to the end of this tutorial. Let us summarize.
05:31 In this tutorial, we learnt to:

interface a LCD to Arduino board and

write an AVR-GCC program to display a digit on LCD.

05:43 As an assignment-

Modify the above code to display any other digit from 0-9.

Modify the above code to build a counter which counts from 0 to 9.

05:57 The video at the following link summarizes the Spoken Tutorial project. Please download and watch it.
06:05 The Spoken Tutorial Project team:

conducts workshops and gives certificates. For more details, please write to us.

06:15 Please post your timed queries in this forum.
06:19 Spoken Tutorial project is funded by NMEICT, MHRD, Government of India. More information on this mission is available at this link.
06:29 This tutorial has been contributed by FOSSEE and Spoken Tutorial Project, IIT Bombay.

This is Priya from IIT Bombay, signing off. Thanks for watching.
