The goal of this project was to study the AVR microcontollers. The following is a CodeVisionAVR project that can be used to build a new firmware for the microcontroller. As a SPICE system to simulate the circute you can use the Proteus project that is already configured.
The circute consists of 8 red LED (2.2V, 10mA), 8 resistors (300 OHM), power source (5V), button, ground and a ATtiny2313 microcontroller.
The program should simulate a loop of running lights, pushing the button makes it change the direction.
The most optimal way is to use the CodeVisionAVR or AVR Studio to build the project, but you can still compile it in Linux. You must install the following libs:
apt-get install avr-libc
apt-get install gcc-avrAfter installation execute the following commands:
# Create ELF executable
avr-gcc -mmcu=attiny2313 -Os -DF_CPU=1000000UL -Wall -std=gnu99 -o main.elf main.c
# Convert it to HEX firmware
avr-objcopy -O ihex -R .eeprom main.elf main.hex
