AVR ATmega8 cookbook

Software requirements

Install libraries required for AVR programming, compiling and deploying

sudo apt install gcc gcc-avr avr-libc binutils-avr avrdude

You will also need any text editor or your favourite IDE

Example codes

00_test

Basic configuration with one blinking LED to test your environment

01_led-binary-timer

Simple binary counter with 8 LEDs display

02_led-wave

Make wave with 8 LEDs (same scheme as 01_led-binary-timer)

03_lcd-hd44780

Initialization and usage of liquid-crystal display HD44780 with FizzBuzz as example

Compiling and programming the ATmega8

There is deploy.sh script in every example directory that does all the work:

# Compile code to Executable and Linkable Format  
sudo avr-gcc -mmcu=atmega8 main.c -o main.elf
# Copy ELF file into a new Intel HEX format file
sudo avr-objcopy -O ihex main.elf main.hex
# Program main.hex into the microcontroller
sudo avrdude -c usbasp -p m8 -U flash:w:main.hex
