| 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 tutorial 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 initialise 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.
