Revision as of 16:29, 26 October 2018

Time Narration
00:01 Welcome to the Spoken Tutorial on AVR-GCC programming through Arduino.
00:08 In this tutorial, we will learn to: interface a seven segment display to Arduino board,
00:15 write an AVR-GCC program to display a digit on seven segment display and

display digits 0 to 9 on the seven segment display.

00:27 To follow this tutorial, you should have basic knowledge of :
00:31 electronics,
00:34 C Programming and

AVR-GCC.

00:39 To record this tutorial, I am using: Arduino UNO Board and

Ubuntu Linux operating system version 14.04.

00:50 GCC stands for GNU Compiler Collection.
00:54 It is a compiler which supports various programming languages.
00:59 AVR-GCC is a part of GCC and supports compiling C programs for AVR microcontrollers.
01:08 Since Arduino uses ATMEGA328P, this is a suitable compiler.
01:15 We also require some external devices such as: Seven-Segment Display,
01:22 220 ohm Resistor,
01:26 Breadboard,
01:28 Arduino UNO Board

and Jumper Wires.

01:33 In this experiment, we will be using the common anode seven-segment display.
01:39 Please refer to the basic level tutorials of this series to know more about Seven segment display.
01:46 Refer the pin mapping for Arduino and microcontroller.
01:51 Do the circuit connection as shown here.
01:55 The Dot pin of the Seven Segment Display is connected to the pin 13 of the Arduino.
02:02 Any one of the common pins is connected to the +5 Volts through a resistor.
02:09 This is the live setup of the connection.
02:12 Now, we will write an AVR-GCC program to blink the Dot LED on the seven segment display.
02:22 We need to install AVR-GCC assembler and an AVR-LIBC library.
02:29 AVR-GCC will generate a hex file and upload it to Arduino board.
02:35 AVR-LIBC contains the required library files that can be used in the program.
02:42 Open the terminal by pressing Ctrl + Alt + T keys together.
02:48 Type: sudo space apt hyphen get space install space avr hyphen libc space gcc hyphen avr

and press Enter.

03:03 Enter the administrative password if prompted and press Enter.
03:09 We can see the installation process has begun.
03:13 Press 'Y' wherever there is a prompt during installation to confirm the configuration.
03:20 Installation will take some time to complete depending upon the internet speed.
03:26 We can see that the installation has been completed successfully.

Let me clear the terminal.

03:34 Now, let us connect the Arduino board to the computer.
03:38 To check the port number of Arduino, I will type: ls space forward slash dev forward slash ttyACM asterisk and press Enter.
03:51 We can see the output as shown. Here ttyACM0 represents the port number of Arduino.
04:00 You may get a different port number. Make a note of your port number.
04:06 Download the file Makefile from the Code files link of this tutorial.
04:12 Makefile enables us to create a dot hex file and upload it to Arduino.
04:19 Save the Makefile in the folder where you will be saving the C program.
04:24 Let us write the avr-gcc program to blink the Dot LED and upload it to the microcontroller.
04:32 Open any text editor and type the following.
04:36 We have to include the libraries required for our program.
04:41 avr slash io dot h contains all the basic libraries required to perform the input and output operations.
04:50 util slash delay dot h contains the libraries for the delay function.
04:56 Arduino board has an LED at PB5.
05:00 Set PB5, that is pin 13 of Arduino as output.
05:05 Sending 0 to PB5 turns on the LED.
05:09 Sending 1 to PB5 turns off the LED.
05:13 These two steps will run in an infinite while loop making the LED blink.
05:19 Source code that are used in this tutorial are available in the Code Files link of this tutorial.

You can download and use it.

05:28 I’ll save the code as dot hyphen blink dot c in the Downloads folder.
05:37 Switch to the terminal.
05:39 Go to the Downloads folder where dot hyphen blink dot c file is saved.
05:45 Type: make space FNAME in capital equals dot hyphen blink and press Enter.

This command creates a dot hex file and uploads it to the Arduino.

06:00 Now, you can see that the Dot LED in the seven segment is blinking.
06:06 Next, we will display digit 2 on the seven segment display.
06:11 To display '2', a, b, d, e, g segments should be high and the other LEDS should be low.
06:19 Pins a, b, c, d, e, f and g of the seven segment display are connected to the pins 2, 3, 4, 5, 6, 7 and 8 of the Arduino respectively.
06:32 The common pin is connected to +5 Volts through resistor.
06:37 Let us see the live connection setup.
06:42 Let us see the source code for this program.
06:46 Open any text editor and type the following code.
06:50 The first two lines of the code in the 'main' function set pins 2 to 8 as output pins.
06:58 The codes inside the while loop are used to control the state of the respective LEDs.
07:05 Sending 0 will cause the LED to glow and sending 1 will turn it off.
07:11 Save it as two.c file.
07:15 Switch back to the terminal.

Clear the terminal now.

07:21 Type: make space FNAME in capital equals two and press Enter.
07:30 Now you can see that the digit two in the seven segment is glowing.
07:38 Pause the tutorial and do the below assignment. Modify the above code to display any other digit from 0 to 9.
07:48 Next, we will display the numbers 0 to 9 on the Seven Segment Display.
07:54 Setup remains the same.
07:57 Let us see the source code for this program. Open any text editor and type the following code.
08:04 The for loop is used to count from 0 to 9.

Each time, the variable 'i' is incremented by one and the value is passed to 'sevenseg' function.

08:16 The 'sevenseg' function receives an integer ranging from 0 to 9.

Based on the input, the case structure is executed.

08:27 Thus displaying the digits from 0 to 9.
08:32 Save it as counter.c file.
08:36 Switch back to the terminal and clear it.
08:40 Type: make space FNAME in capital equals counter and press Enter.
08:50 Now, we can see the digits 0 to 9 are displayed in the seven segment display.
09:02 This brings us to the end of this tutorial. Let us summarize.
09:06 In this tutorial, we learnt to interface a Seven-segment display to Arduino board,
09:13 write an AVR-GCC program to display a digit on seven-segment display and
09:19 display digits 0 to 9 on the Seven segment display.
09:24 The video at the following link summarizes the Spoken Tutorial project.

Please download and watch it.

09:32 The Spoken Tutorial Project team conducts workshops and gives certificates.

For more details, please write to us.

09:42 Please post your timed queries in this forum.
09:46 Spoken Tutorial project is funded by NMEICT, MHRD, Government of India.
